How it works

Water cooled systems are plumbed directly into your water supply. They use the cold water in a controlled manner to cool the air through the piping system. Unlike traditional air conditioning systems, water cooled units do not require an outdoor unit. The internal condenser is usually hidden within the property in a concealed space such as a cupboard or under the kitchen sink.

Frequently Asked Questions about our water cooled internal condenser units

Some of your questions about our water based air conditioning answered.

Yes, installing a water cooled air conditioning systems or through the wall air conditioning is the only option you have in a listed or restricted property. Contact us if you would like to discuss getting a water based AC in your home.

In most cases no, a water based AC unit has the internal condenser hidden in your own home so there is no need for permission.

A typical single split type AC unit will take 1-2 days to install. We can give you a good estimate if you contact us and inform us about your property and what you require.

Modern units are very quiet. In the workplace, you rarely notice them while in bedrooms at night time certain specific night set back settings slow the fans down to reduce the cooling requirement in line with falling ambient temperatures.

The electrical power consumption of an average size AC system will be little more than a domestic fridge. The cost of the water consumption element depends on how and what you pay for your water, and indeed the usage characteristics of the user. Water consumption rates vary on unit size and our specialists can advise you according to your requirements.

Air conditioning works by way of transferring heat from the air inside a room into the internal gas and then pumped along the pipework to an outdoor unit where the gas transfers the heat to the external air. The heat exchange process happens when the internal air is passed over a heat exchanger coil called an evaporator. Inside this evaporator is refrigerant that boils off at a very low temperature making the coil very cold. When the warm air passes over it then heat is absorbed from the air into the coil. The reverse happens with the heat exchanger in the outdoor unit.

In a water based air conditioners, water is used throughout the system. There are some water based air conditioning systems in the market, such as evaporative coolers, but they are not as efficient as a traditional air conditioning system.

A water cooled system, which we offer is a traditional AC system but with the addition of water use. The features we list above are not available through the other water based system.
