Air Conditioning Frequently Asked Questions

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 even quieter performance, they can be installed in a cupboard or fitted with an acoustic jacket, 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.

Yes, you can install a water cooled air conditioning system in your apartment even if you have no outdoor space. Our systems are ideal for apartments, listed buildings, or any properties where external modifications are not possible or permitted.

Yes! Listed buildings often come with restrictions that prevent any modifications to the exterior of the property, which means conventional air conditioning systems requiring an outdoor condenser are usually not allowed. Our water cooled systems overcome these challenges and provide efficient cooling without impacting the building’s aesthetics or needing planning permission.

There are numerous benefits to our water cooled air conditioning system. Here are some of them:

1. No external unit or planning permission required
2. Maintains the visual appeal of your property
3. Cool multiple rooms simultaneously
4. Control the temperature of your property from anywhere
5. Adds to your property's value and rentability
6. Quick installation with minimal disruption
7. Peace of mind 5 year warranty cover

Portable air conditioning units can be useful in some situations, but they do come with several drawbacks. They're noisy, require an open window for the hose, and are somewhat inefficient as they pull in air that has already been cooled in the room over the condenser to discharge outside. Plus, they usually operate on a fixed speed – meaning they just turn on and off.

In contrast, our internal room units that connect up to our water cooled condenser are virtually silent, let you keep your windows closed, and filter the air. They're also inverter controlled, which means they adjust the compressor speed to maintain a stable room temperature while using less electricity.

Yes! In fact, water cooled systems can be even more effective than conventional air conditioning. This is because, even when outside temperatures soar above 30 degrees, the water entering your property still stays typically at a much cooler temperature, around 20 degrees Celsius or below. This allows our water-cooled systems to remove heat more efficiently, providing you with a cooler and more comfortable environment.

The cold air from our internal room units is just as cool as that from a conventional air conditioning system - or even the air conditioning in your car. An efficient system will deliver air that's 10-12 degrees Celsius cooler than the room temperature. So if it's 23 degrees Celsius inside, you can expect refreshing air at around 11-13 degrees Celsius.

Conventional air conditioning systems have both an internal room unit and an external condenser unit, which are connected by refrigerant copper pipes. The external units, often noisy and unsightly boxes located on the outside buildings, are the condensers. These condensers use external air and a fan to reject the heat from the condenser coil. An internal water cooled system works in a similar way, but with one key difference. Instead of using air to cool the refrigerant, the system uses water instead. The internal room units are still connected via refrigerant pipes, but the condenser unit uses water to cool the refrigerant in the system.

Our water cooled system does provide heating; however, we advise only using this as a backup and not a primary source of heating for your property.

If you're wondering, do you need planning permission for air conditioning?—the answer is no, not with our fully internal water cooled air conditioning systems. Because they don’t require an external unit or any changes to the exterior of your property, planning permission isn't necessary. This makes the system ideal for apartments, listed buildings and properties located within conservation areas, as it doesn't have an external unit and no external modification to the property are required.

Water cooled air conditioning systems are specifically designed for apartments, flats, listed buildings or properties in conservation areas where conventional air conditioning systems with external condensers are unable to be installed.
