Traditional air conditioners have two main components: the internal fan unit and an outdoor condenser unit. The use of outside units has been restricted in built-up urban areas such as London. This is partly due to their visual impact, particularly when it comes to apartment blocks or listed buildings. In addition, outdoor condensers can cause noise issues for neighboring properties. Air conditioning without an outside unit can overcome these restrictions.

Why Do I Need Air Conditioning Without Outside Unit?
Have you been told that you cannot install an external condenser? Has your planning permission application for air conditioning been denied? Internal air conditioning is the ideal solution for you. Internal air conditioning systems are a great alternative to traditional air conditioning. If you live in a city such as London or a conservation area, installing outside condensers is restricted and often not permitted. This is especially true for apartments and listed buildings. You can overcome these restrictions with an internal water cooled condenser.

Where Can I Install An Indoor Condenser?
Indoor condensers are compact and easy to conceal. Installation engineers usually hide the internal condenser in spaces such as hallway cupboards or under the kitchen sink, depending on your available space. This means that you do not need to compromise on the visual aesthetic of your home and can install an internal condenser even if you are limited in space.

How Does Internal Air Conditioning Work?
Water cooled systems (air conditioning without an outside unit) 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.
What Are The Benefits Of Air Conditioning Without Outside Unit?
There are many benefits to internal AC units, also known as water cooled air conditioning. Firstly, they allow everyone to enjoy access to air conditioning, regardless of property restrictions. Their benefits include:
- Suitable for Grade II listed buildings and apartments
- Condenser is hidden in concealed space
- No planning permission required
- Reduced water consumption
- Energy efficient
- Low noise & Wifi control
