Air Conditioning Frequently Asked Questions

Our air conditioning units are sleek and stylish, with a clean design that fits seamlessly into the decor of any apartment. With both wall mounted and ducted options, there’s sure to be an option that matches your requirements.

Yes, our internal water-cooled solution is the best alternative when you are not allowed (or don’t have room) to install a condenser on the outside of the property.

As our systems are fully internal there is no requirement to apply for Planning Permission or carry out a noise survey. If you are a leaseholder, we would always recommend checking your lease to see if internal works are permitted without notifying the freeholder, but you will definitely not need local authority approval.

This depends on your insurance. You may need to add your air conditioning unit to your home insurance so it’s covered by named instances. If in doubt, contact your insurer to find out if your AC is covered or if you need to increase your premium to cover it.

Modern air conditioning costs far less to run than people think because they are much more energy-efficient. Our internal water-cooled air conditioning system, for example, is rated AAA for energy efficiency.

Typical air conditioning systems provide 3kw of cooling with just 1kw of electricity used.

‍

The size of the unit is determined by the cooling capacity required by the room. A small 2kw model is very compact and is just under 800mm wide.

Yes, if you were to sell or move out of your property and you wish to take your system with you we would need to attend and decommission the system. This would involve pumping down the system so the refrigerant is safely stored inside the condenser unit, isolating the electrical power and communication cables and then taking down the units from the walls - please note that there will be some small holes in the wall that would need to be repaired after the wall units have been taken down.

Our wide range of internal water air conditioning systems provide a cooling capacity of up to 15kw and a cooling power input of up to 5kw. This makes our internal systems as powerful and efficient as any conventional air conditioning unit.

Our internal water cooled air conditioner can supply up to 8 rooms with cool air at the specified desired temperature, easily controlled with our smartphone app or remote.

The Urban Designer wall-mounted unit has the following dimensions:

• Height: 300 mm
• Width: 980 mm
• Depth: 210 mm

This unit is designed to combine modern aesthetics with high functionality, making it a great choice for various room sizes.

It is a huge myth that air conditioning can make you ill or cause you to catch a cold. Not only can air conditioning not chill you enough to get ill, but it is also likely to help improve your health.

Urban Cooling are specialists in water-cooled air conditioning solutions for apartments, listed buildings, and residential properties across London and the South East. With over 40 years of combined experience, they lead the market in fully internal air conditioning systems that require no external condenser units.

Urban Cooling provides expert installations that overcome planning restrictions and aesthetic concerns, helping homeowners and property developers achieve efficient, discreet climate control without external modifications. Their innovative water-cooled air conditioning systems are the perfect choice for properties where traditional external units aren’t an option.

When conducting a video consultation, with the surveyor you'll simply

• Walk them through the rooms you'd like cooled,
• Show them where you'd like your units installed.

During the pre-installation survey  the surveyor will confirm your properties details to ensure there are no surprises on installation day. to do this they will need to see:

• The rooms where you would like air conditioning installed
• Your preferred location for the internal condenser unit
• The ceiling space between the indoor units and the condenser location (to check for a false ceiling that can accommodate pipework)
• Mains water and drainage connection points for the condenser
• A picture of the fuse board (to check if there is a spare circuit available for the condenser)
• The type of wall construction in your property (e.g. stud or solid walls)

A water cooled air conditioning system can cool your room to the same temperature as a conventional air conditioning system, typically around 18°C. However, we recommend setting the room temperature to 21–22°C, as 18°C can feel quite cold.

All air conditioning systems generally lower the room temperature by 10–12°C. For example, if the room starts at 26°C when the system is turned on, the air coming out of the unit will be between 14–16°C. As the room temperature drops to 21°C, the air exiting the unit will be around 9–11°C.

It's important to note that the setpoint temperature on the remote control refers to the desired room temperature, not the temperature of the air coming out of the unit. Lowering the setpoint will not make the air coming from the unit colder; this is determined by the temperature of the air entering the system.

The ideal temperature for a home varies depending on personal preference, but setting your air conditioning unit between 20 °c and 22°C offers a great balance of comfort and energy efficiency. It’s worth adjusting your system slightly to discover what feels best for you.

Yes, air conditioning can contribute to better air quality in your home. Our indoor units have washable air filters that purify the air by capturing dust, moisture, bacteria, and airborne pathogens. This significantly improves indoor air quality, making it healthier for anyone with asthma, allergies, hay fever, or other respiratory conditions.

With our air conditioning systems, there’s no need to open windows and let in outdoor pollutants—perfect if you live in a busy or polluted urban area.

‍

Yes, our air conditioning systems can help to reduce humidity in your property. Not only does water cooled air conditioning blow cool air into your property, it also removes heat and humidity by passing the air through cooling coils. This helps to remove extra moisture from the air so it doesn’t feel so humid.

‍

Yes, we offer a full parts and labour warranty for 12 months on our Incognito® system. This warranty can be extended for an additional two years with full parts and labour coverage, followed by a further two years covering parts only. An extension of the warranty is subject to an annual service being completed by our aftercare and maintenance team, where it is cleaned, tested, and checked.

Our annual maintenance charges are as follows:

• £200 + VAT for one to three indoor units
• £250 + VAT for four to seven indoor units
• £300 + VAT for eight + units

(Prices subject to change depending on how many condensers are installed)

We connect each indoor unit to the condenser unit using two insulated refrigerant pipes and communication cables, which run through access holes we cut into the plasterboard. We then do the same to connect up the outdoor Condenser Coil, also using two insulated refrigerant pipes and communication cables. Once fitted, the system is then pressure tested, and the plasterboard access holes are re-installed.

We complete your installation by fully testing and commissioning the system, before providing you with a demonstration. You may require a decorator to fill and paint the access holes that have been created during the installation. We can either put you in touch with one of our recommended decorators or you can source your own. If you choose to use one of our decorators, this will cost £350 for up to 10 access holes and would be payable directly to them.

Yes, it is possible to have an Incognito air conditioning system with just one indoor unit. However, since the compressor box and condenser coil are essentially the same as those used in a two-port condenser, the price for a single unit option is slightly higher than that of a single-system water-cooled equivalent.

Our Incognito® air conditioning systems start from £8,960 for two wall-mounted units. 

• Urban Compact: £8,960 (2 units) - £10,560 (3 units)
• Urban Designer:  £10,480 (2 units) - £12,915 (3 units)‍
• Ducted - £11,580 (2 units) - £14,415 (3 units)

We offer a range of indoor room units to choose from as part of our Incognito® system, these include:

• (Wall-mounted) Urban Compact - Designed for properties that are limited on space or want a more discreet system. This solution not only offers functionality but also provides the flexibility to customise the wall units in four different colours (Urban Grey, Silver Grey, Stone and Ivory).
• (Wall-mounted) Urban Designer - Combining modern design with high functionality. These wall-mounted units feature swappable textile covers, allowing you to customise the unit to match your room's decor.
• Ducted - Maintain a seamless look within your property by choosing a ducted unit hidden behind a modern and minimalist grill.

The Incognito® is very energy efficient in both heating and cooling modes with an Energy Efficient Class and Label rating of A++.

The Incognito® system offers extensive customisation options. From tailoring the colour and design of the external Condenser Coil to choose the indoor unit style and colour to match the style of your home.

Our Incognito® air conditioning solution can be installed in a variety of residential and small commercial properties.

The Incognito® system is perfect for one or two bedroom apartments and residential properties that have either a balcony or outdoor space.

In certain instances planning permission would be required to install the Incognito® system. We do advise that you check this prior to making an enquiry.

The key features and benefits of the Incognito® system include the following:

Modern and Customisable Design

Unlike traditional systems our Incognito system has been created with visual aesthetic at the forefront of its design.

With a selection of high quality indoor wall units available in various colours, as well as the option to customise our Urban Designer wall units with your own fabric, your system can be fully tailored to complement your property's style.

In addition to our customisable wall units we also have a range of pre- made Condenser screen designs for you to choose from, as well as the option to design your own.

Space-Saving Compact System

We’ve split the traditional external condenser in two parts, an external condenser coil and internal compressor box, to allow the system to seamlessly integrate into your property and occupy minimal space.

Built for properties with various amounts of outdoor space, even apartments with balconies, the slimline condenser coil effortlessly fits onto an external wall. While the internal compressor box maximises the dead space within your property by being fitted in a cupboard or utility room.

Energy Efficient Heating and Cooling

Rated A++ for energy efficiency, our system hasn’t just been engineered for aesthetic appeal, but also to excel in performance, ensuring unparalleled air conditioning comfort even in the heights of summer and winter. It's also means that your electricity bill won't sky- rocket and is cheaper to run than most portable AC options.

The system will allow you to cool or heat up to three rooms simultaneously. Moreover, you will also have the added benefit of being able to independently control the temperature in each room when in either cooling or heating modes. However, please note that the system can either cool or heat all rooms at the same time, not a mix of both.

Quiet Indoor and Outdoor Units

Our Incognito® system connects up with a variety of indoor units to provide you with a whisper quiet cooling solution.

The Internal Compressor Box operates at around between 44-49 decibels, which is similar to a quiet washing machine. However, they can also be installed in a cupboard or an acoustic jacket can be fitted over the unit to hide the noise further. Meanwhile the External Condenser Coil is even quieter operating at around 35 decibels.

Each system could be classed as being 'better' in certain situations. For example in instances where external modifications are restricted, such as with listed buildings, the Water Cooled system would be a much better solution as it is fully internal.

The Incognito® system delivers the same performance as conventional air conditioning units, as essentially the system uses all the same elements. However, in our Incognito® system, these elements are split up and seamlessly integrated into your property.

Our Incognito® system works in the same way as a conventional air conditioning system, except the condenser has been split into two components; a compressor box that can be installed internally or externally, and a condenser coil located externally, such as a balcony or garden space. 

By splitting the major components, the compressor box can be packaged up into a smaller and quieter housing, which in turn allows for more locations for it to be installed. Heat absorbed from the property is rejected from the designer slim profile condenser.

The compressor box is then connected via refrigerant pipework to the internal units that discharge the conditioned air. As with conventional air conditioning internal units can be wall, floor, or ceiling mounted.

Yes, air conditioning units do need to be serviced to ensure they operate efficiently and last as long as possible. We recommend having your system professionally serviced once a year. Regular maintenance helps prevent breakdowns, improves performance, and keeps your unit running at peak efficiency.

As long as the system is serviced annually by our engineers to ensure it is functioning correctly and efficiently, post-installation repairs should not be necessary.

Our water cooled systems only use water in the condenser unit, with no water running through the pipework connecting the indoor unit to the condenser. The water cooled condenser units are manufactured to the highest standards, with all internal components fully brazed to minimise the risk of leaks. This makes the likelihood of a water leak similar to that of a washing machine or dishwasher within your home.

If any issues arise with your system after installation, simply contact our aftersales customer service team. They will dispatch a senior aftersales engineer to inspect and resolve the issue. Your system is covered by a 5-year warranty, provided that annual maintenance is carried out.

Water cooled air conditioning systems are exceptionally reliable and robust. At Urban Cooling, we have installed thousands of systems, with numerous satisfied customers and hundreds of positive reviews, read some of them here.

Yes, we provide a comprehensive parts and labour warranty for 12 months. This warranty can be extended by an additional two years, covering both parts and labour, followed by a further two years with parts-only coverage. The warranty extension is contingent upon an annual service carried out by our aftercare and maintenance team, during which the system is cleaned, tested, and inspected.

Our annual maintenance charges are as follows:

• £200 + VAT for one to three indoor units
• £250 + VAT for four to seven indoor units
• £300 + VAT for eight + units

(Prices subject to change depending on how many condensers are installed)

If would like to book a video consultation either:Complete our ‘Video Consultation Request’ form with the day and time  you would like and one of our team will then contact you to confirm our surveyors availability and book your consultation appointment. See a link here 

Call us directly on 020 8080 9708 to speak to one of our customer service team and arrange a video consultation date and time that suits you.

Following the video consultation, our surveyor will enter the information into our database and select the appropriate capacity indoor units needed to air condition the specified rooms. They will then prepare a quotation based on your requirements, which will be emailed to you, typically within 72 hours of the site survey.

Using WhatsApp or FaceTime, you’ll be required to guide the engineer around your property using your mobile device and show them the rooms where you would like air conditioning (please note you’ll need a tape measure handy). This will also be the time to ask any questions you may have.

From this consultation, your surveyor will prepare and send you an accurate quote tailored specifically to your property.

Once you've accepted your quote, we'll schedule an in-person survey at your property. During this pre-installation survey, the surveyor will confirm your properties details to ensure there are no surprises on installation day and explain exactly what to expect during the installation process.

If everything’s good to go, we’ll confirm your final price and set your installation date. In the rare event that additional work is identified during the survey, we’ll update your quote accordingly before proceeding.

Unfortunately, as every property’s needs are different, we are unable to provide you with an accurate quote online.

The price of the installation will change based on several factors, such as the number of rooms that need cooling, the size of the condenser required, and the structure of the property.  We can say that our Urban Compact range of fully internal water cooled systems start from £3,990 plus VAT.

‍

We can say that our Urban Compact range of fully internal water cooled systems start from £3,990 plus VAT. 

‍

To receive an accurate quote for your property, we need to conduct a survey. We offer several survey options to suit your needs:

• On-site Survey: One of our expert engineers will visit your property.
• Video Survey: Conducted via WhatsApp or FaceTime.
• Online Self Survey: Available if you live in an apartment built after 2000.

To learn more about these options, click here.

For wall-mounted units, we need to cut small holes to run the pipework. These holes are hidden behind the wall-mounted units and will not be seen. In properties with solid walls, we have two options: 

‍

The first is chasing the wall to hide the pipework inside, please note this option does create a bit more dust. The second option is boxing in the pipework or using plastic trunking. Our surveyors will determine the best approach based on your wall construction.

In most cases, our water cooled air conditioning installation will require our engineers to cut small holes in the ceiling, to pull pipework from the indoor units to the condenser unit. While our engineers will replace the plasterboard, you will need to fill and paint over these holes. 

‍

This requirement is noted in our quotation, and we can recommend a painter and decorator who charges £350 + VAT for up to 10 holes. If your system has three or fewer indoor units, you will typically have under 10 holes to repair. For more than 3 units, the number of holes may exceed this limit. You are free to use our recommended decorator, do it yourself, or hire another professional.

We kindly ask that any wall decorations and furniture are removed from the area that our engineers will be working in prior to the installation, our insurance prohibits our engineers from moving them in case of accidental damage.

Further details of what you will need to do before can be found in our pre-installation guide that will be sent to you once you have booked your installation with us.

No, we don’t offer self-installation because our air conditioning units require expert fitting to ensure safety, efficiency, and long-term performance. So, if you're wondering "can I install air conditioning myself?"—the answer is no. All of our systems must be installed by our qualified engineers, and every purchase includes full professional installation.

‍

We recommend allowing one day per indoor unit. In many new builds, the installation can be quicker, often completing two or three units in one day. However, we prefer to allocate extra time to account for any unexpected difficulties.

Our friendly installation team are all experienced, F-Gas registered engineers that work for Urban Cooling. 

We are experienced in working with many manufacturers and are approved installers for Panasonic, Daikin, Mitsubishi, Toshiba and Fujitsu equipment.

You can book your installation at any time once the deposit invoice is paid. Depending on the time of year, installations can be scheduled as soon as 7 days after payment or up to a year in advance. During busy periods, our waiting times may extend up to 4 weeks.

If you’re renovating, we recommend scheduling the first fix installation as early as possible, usually right after stud walls are in place. This timing helps in planning the air conditioning pipework alongside other trades like plumbing and electrical work.

Despite using professional cutting and dust extraction systems, our installation teams put down dust sheets and cover furniture. However, we just want to give you a heads-up that some airborne dust may still settle on your furniture, which can be easily cleaned with a duster.

Unfortunately, water cooled condenser units can't be installed on balconies as there's usually no nearby water supply or waste connection. 

However, if you are allowed an external condenser our Incognito® systems might be the perfect option for you as it is designed for properties with balconies and blending into your property exterior. To read more about our Incognito® system click here.

Yes, our water cooled condensers use an oil lubricant that needs to stay at the bottom of the unit to work correctly. So keeping the condenser vertically upright is a must!

Our water cooled condenser units require a minimum clearance of 15 cm on the right-hand side for pipework and 10 cm above the unit to allow the lid to be removed during maintenance and servicing.

The condenser unit should be installed in a location with access to a mains water supply, a waste drain connection, and sufficient clearance around the unit for pipework and maintenance. 

From our experience of installing over a thousand of these systems the following areas within an apartment or flat are ideal for installing the condenser unit:

• In a utility room
• Under a sink
• In an airing, boiler or storage cupboard
• In a kitchen unit

Yes, our systems are able to be installed over multiple floors as long as the height does not exceed 8 metres from the condenser to the indoor room units. We can also cool up to five rooms with one of our internal condensers.

Our fully internal water cooled system doesn’t require an external unit or any modifications to the property’s exterior at all.

The installation process for this system is straightforward and takes on average one day per indoor unit.

Firstly, we install the condenser and connect it to your water mains, drainage and electrical supply. Its compact design makes it easy to conceal in a utility room or cupboard.

Next the indoor units (which can be wall mounted, floor mounted or ducted) are installed in each room which requires cooling. The optimal locations are established at survey stage, ensuring the property is cooled in the most efficient way.

We connect each indoor unit to the condenser unit using two insulated refrigerant pipes and communication cables, which run through access holes we cut into the plasterboard. Once fitted, the system is then pressure tested, and the plasterboard access holes are re-installed.

‍

We complete your installation by fully testing and commissioning the system, before providing you with a demonstration.

‍

You may require a decorator to sand, fill and paint the access holes that have been created during the installation. We can either put you in touch with one of our recommended decorators or you can source your own. If you choose to use one of our decorators, this will cost £350 for up to 10 access holes and would be payable directly to them.

We accept all major debit and credit cards. However, we can also accept payment via bank transfer if this is easier for you.

We’re often asked about financing for air conditioning units, but at this time, we do not offer finance payment options for our systems. While we previously provided air conditioner financing, it wasn’t widely used as most customers preferred to pay using low-interest credit cards. Due to low demand, we decided to discontinue our financing for air conditioning units.

‍

Upon accepting our quotation, we kindly ask for a 75% deposit to place the materials and units on order and to secure your installation slot. The remaining 25% will be invoiced to you upon completion of the commissioning of the system.

Yes, we offer two ways to receive an air conditioning discount on your installation:

Referral Discount: Simply refer us to your neighbour via an introduction email. If your neighbour places an order, we will pay you £150 for each referral.

Group Discount: If you form a small group of neighbours who are all interested in proceeding with an order, we can offer up to a 10% discount to each group member, depending on the group size. The only condition is that all members of the group must have their installations carried out simultaneously.

‍

If you're wondering how much it costs to run a water cooled air conditioner, our systems are designed with energy efficiency in mind. For example, a 3kW air conditioning condenser typically uses only around 1kW of electricity, thanks to its efficient inverter technology.

To calculate the running cost of air conditioning, take the rated output of the condenser we’ve quoted (e.g. 3kW), divide it by three (1kW), and that gives you an estimate of the kilowatt-hours used per hour at full power. Multiply that figure by your electricity rate per kilowatt-hour to get an idea of the hourly cost.

Our systems are also inverter-controlled, which means they automatically adjust power usage as the room approaches your desired temperature. This smart control reduces energy consumption further, lowering the running cost of your air conditioning over time.

‍

Our quotations include everything from the units themselves to installation, apart from two things:

The first is if you require an electrician to provide the electrical power supply to the condenser unit, either via a switched spur or directly from your fuse board. Our recommended electrician typically charges £150 plus VAT for a switched spur or £300 - £350 plus VAT for wiring into a fuse board. Upon completion, the electrician will provide an electrical installation certificate as required by Part P of the building regulations. You are also welcome to use your own electrician if you prefer.

The second is post installation decorating costs. Some minor decoration work may be required to 'make good' of the holes we need to cut in the ceiling to install the pipework. We can recommend a decorator who charges £350 + VAT for this work, though you do also have the choice to use your own preferred decorator or complete the work yourself

Please note. We do not make any profit on top of the electrician or decorators services, therefore the charges for both are payable directly by you.

Conventional air conditioning systems are mass-produced, mostly in China, which drives costs down due to cheaper labour and large-scale production. Our internal water cooled systems are not made in such vast numbers and are proudly manufactured right here in the UK. This ensures top-notch quality and supports local craftsmanship, which we believe is worth every penny.

Our water cooled air conditioning system costs start from £3,990 for a single wall-mounted unit. Pricing varies depending on the number and type of units installed. We a free 'no obligation' video consultation to provide you with an accurate quote.

Should you wish to upgrade your current system and want to add additional indoor units at a later date, this is possible. However, it would need to be discussed with one of our surveyors during your video consultation. This will allow our surveyor to choose the correct condenser for the upgrade.

Want to know how to use your air conditioner effectively? Our air conditioning systems can be controlled by an infrared remote or via our app anywhere with WiFi. Set a temperature for the system to cool the rooms to and it will automatically switch off when it reaches that setpoint temperature.

‍

If you're wondering how noisy air conditioning units are, you'll be pleased to know that our internal wall-mounted systems are among the quietest on the market, operating from just 19 dB(A).

Urban Designer: 19 - 22 Db(A)

Urban Classic: 19 - 30 Db(A)

Urban Compact: 24 - 36 Db(A)

Our water-cooled condensers are also very quiet, similar to the sound of a quiet washing machine. We can also line the inside of the utility-cupboard door with egg-shell acoustic foam to absorb the sound further.

‍

Yes all of our wall-mounted come in a range of colours:

Urban Designer: This unit has swappable textile covers that can be customised to match the style of any room. You can choose from the variety of ready-to-go colours listed below or customise your own to fit your properties interior decor.

• Bluish Grey
• Light Grey
• Emerald Blue
• Dark Brown
• Dark Grey
• Grey Beige

Urban Classic: This range is available in three colours white, silver & grey.

Urban Compact: Available in four different colours to blend with your home's decor.

• Urban Grey
• Silver Grey
• Stone
• Ivory

The size of the wall-mounted unit depends on the room's cooling capacity requirements. We offer a wide range of wall-mounted units designed to meet different cooling needs. Our units come in various sizes, starting from the Urban Compact model at 715mm wide, up to the Urban Classic model, which is 1040mm wide.

Our showroom is located in Chatham, Kent and visits are by appointment only. To view air conditioning units near you, call us on 020 8080 9708 to arrange a time.

Yes, ducted air conditioning systems can be installed above the ceiling, but your property must have a false ceiling void of at least 250mm to accommodate the ducted unit and associated ductwork. This setup allows for a sleek, hidden installation, ideal for maintaining a clean and modern interior.

If you’d like your ducted air conditioning system fully concealed behind a minimalist grille for a seamless finish, this option is available at an additional cost of £1,200 per unit.

When selecting the best indoor air conditioning units, it's important to consider your style preferences, budget, and the layout of your property. All our internal units work by drawing in warm air and circulating cool air back into the room. Wall-mounted indoor air conditioning units are a popular choice—they’re typically more affordable and energy-efficient due to reduced airflow resistance. We offer a wide range of these in various sizes and colours to suit your decor.

For a more discreet option, ducted indoor air conditioning units are installed within ceiling voids and only display a subtle grille. While they require additional space and ductwork, they offer a seamless finish. Speak to one of our surveyors to find out which solution is right for your space.

We offer a range of indoor air conditioning units that connect to the water cooled condenser. These include wall-mounted, floor-mounted or ducted units.

We offer three types of wall-mounted units:

1. Urban Designer - Combining modern design with high functionality. These wall-mounted units feature swappable textile covers, allowing you to customise the unit to match your room's decor.
2. Urban Classic - This range connects our internal water cooled condensers to Panasonic’s Etherea wall-mounted units. This line is known for its sleek design and advanced smart features.‍
3. Urban Compact - Designed for properties that are limited on space or want a more discreet system. This solution not only offers functionality but also provides the flexibility to customise the wall units in four different colours (Urban Grey, Silver Grey, Stone and Ivory).

Yes, our water cooled condensers are compatible with any water softener. We simply take a water feed before the softener, as this helps to reduce salt consumption within the device.

Our recommended water pressure is about 1.5bar. Most modern flats and apartments built in the last 30 years will have a boosted mains water supply and therefore should not have any issues. In older properties, on rare occasions water pressure can be low. If this is the case in your property this will need to be highlighted to one of our surveyors during your pre-installation survey. They will then be able to take a deeper look and advise accordingly.

Water cooled air conditioning only requires a water supply at the condensing unit, it is refrigerant pipework that connects the condenser and indoor units together. So you only need a water supply at the condenser location.

As the wastewater has been heated up to around 45-50degC - it makes sense to try and re-use the heated water. We are able to connect up to a large hot water storage cylinder to the unit, so the heated water can be used for a shower or bath. However, this is not possible in a lot of cases as hot water cylinders do take up a lot of room and they will also add to the cost of installation.

If your building has a communal heating system and or a chilled water circuit then it is possible for our water-cooled condenser unit to connect to these without any waste water at all. This would depend on what water flow temperatures are running through these systems.

A common question we get is: how much water does air conditioning use? The exact amount is actually very hard to determine as usage depends on the following variable factors.

Setpoint temperature: One of these factors is the setpoint temperature of the room that is being air conditioned. This is because more water will be required to bring the room down to say, 18degC than it would if it was set to our recommendation of 22 - 23degC.

Outdoor air temperature: The outdoor air temperature is also going to play an important role in the amount of water consumption. The hotter it is outside the more heat is being transferred from the outdoor air to the cooler room being air conditioned.

Building Materials: Another factor is how your property has been constructed and the type of materials that have been used. A building with a lot of glass and thermal insulation will absorb external heat and retain it in the building for longer.

Input water temperature: As we are using cold water to cool the hot refrigerant, the colder the water that comes into the system, the less that will be required to remove the latent heat from the refrigerant.

Usage: Probably the most obvious is the number of hours the unit is operating for someone who leaves the air conditioning system on all day will require a lot more water than someone that switches the system on for a few hours to cool a bedroom before going to bed.

To give you an idea - an average sized bedroom of, 5m x 4m, with a normal amount of glass windows, well insulated to modern building regs, an outdoor temperature of 27degrees C and an incoming water supply of 12degC - would require a 2kw indoor unit, as well as the condenser unit. This condenser would give out a water flow of 40 litres per hour to cool the room to 22 degrees. 

Our condenser units only use water when the condenser is running to provide cooling. When the room has reached the setpoint temperature of 22 - 23 degC the condenser will switch off. To maintain the setpoint temperature of the room or systems normally only take 20 – 30 minutes per hour of operation, so water consumption will drop when the setpoint temperature is simply being maintained.

Only refrigerant gas flows through the interconnecting pipework — no water passes through the pipes connecting the wall units.

With conventional air conditioning the condenser is located outside, so it can draw in air to cool the refrigerant. In an internal water cooled system the system uses water to cool the refrigerant instead. The water passes over a heat exchanger, this heat is then rejected from the high temperature refrigerant to the low temperature water, which in turn cools the refrigerant.

The air conditioning pipework must run between the indoor units and the condenser, which is usually located in a utility cupboard. A pair of insulated pipes (flow and return) are routed above the false ceiling, connecting the indoor units to the condenser. Alongside the pipework, a communication cable and condensate drain are also installed.

Our internal air conditioning condensers typically use 12mm and 6mm pipework for air conditioning connections. The water connections for a water-cooled condenser are 22mm for both the inlet and outlet. Please note that the air conditioning pipework is insulated for better system efficiency. The insulation adds 9mm to the pipework thickness, so the larger pipework will have an effective thickness of 30mm, and the smaller pipework will be 24mm thick.

Air conditioning systems are generally very efficient, typically providing 3 kW of cooling for every 1 kW of electricity used. For example, if your condenser is rated at 5 kW, it will consume approximately 1.66 kW of electricity. This consumption occurs when the unit is running at full capacity. In practice, as the room temperature approaches the setpoint, the inverter air conditioning system will gradually reduce its output, using less electricity.

Our smaller condensers, under 5.2 kW, can be powered by a 13A fuse. Systems above 5.2 kW will require a larger circuit breaker, typically 25A or 32A, for our largest condensers.

Yes, our fully internal air conditioning systems require an electrical power supply for the condenser unit. The specific requirements depend on the system’s capacity. For systems with a condenser under 5.2 kW, a 13A switched spur connection is sufficient. However, if the condenser is over 5.2 kW, it will need to be connected directly to the fuse board.

You might be asking: is water-cooling quieter than air cooling? The answer is yes. Our internal water-cooled condenser units operate at around 49 decibels—similar to a quiet washing machine. For further noise reduction, we can line the inside of the utility-cupboard door with egg-shell acoustic foam to absorb sound, making them ideal for noise-sensitive environments.

We provide a wide range of condensers capable of supplying between one and five indoor units. This means that our most advanced condenser can effectively manage the cooling needs of up to five separate rooms simultaneously.

We have a wide range of condensers that increase in size depending on the number of indoor units they are required to provide cool air to. The smallest condenser we have is just 500mm x 500mm x 295mm.

Looking for energy efficient air conditioning? Our internal water-cooled systems feature advanced inverter technology and are rated AAA for energy efficiency. They’re designed to deliver powerful cooling while keeping electricity consumption low—making them more cost-effective to run than most portable air conditioning units.
