The primary benefit of the Powrmatic Vision 3.1kW / 3.6kW is its all-in-one design. Because there is no external unit, you can bypass the common restrictions that prevent traditional air conditioning installation. This means:
This innovative approach is why we founded Innovative Air (formerly EHGE Cool Sleep)—to provide sophisticated climate control for properties where others say it’s impossible.
We're in no rush to leave once installed (unless you really want us gone fast). We'll ensure you feel comfortable using your new AC.
Condenserless, but it comes with two external grilles, with an endless choice of colours.
Every Powrmatic Vision unit we install comes with integrated Wi-Fi as standard. Using the dedicated smartphone app, you gain complete control over your home’s climate from anywhere in the world.

As specialist supplier-installers, we offer unbeatable value and a seamless experience. Our team manages every single aspect of the project, meaning you have one point of contact and total peace of mind. Here’s how our proven one-day installation works:
Our visit begins with meticulous planning. We find the optimal position for the unit to ensure perfect air distribution. Using specialist diamond core drills with integrated dust extraction, we create the two 162mm air intake/exhaust holes. This process is precise and incredibly tidy. We then install the subtle, paintable grilles on the outside, ensuring they blend seamlessly with your brickwork or render.
Our qualified electricians handle all the necessary wiring, typically installing a fused spur from a nearby ring main in compliance with all UK electrical regulations. Once the unit is securely mounted on the internal wall, we take care of the finishing. Our service includes making good any plasterwork around the unit, leaving the area clean, tidy, and ready for you to paint if required. We treat your home with the utmost respect.
The final step is to commission the system. We test every function—cooling, heating, dehumidification, and Wi-Fi connectivity. We won't leave until the unit is performing flawlessly and you are 100% satisfied. Our engineer will then provide a full handover, showing you how to use the remote control, set up the smartphone app, and perform simple maintenance like cleaning the filters.

In the vast majority of cases, no. Because there is no external condenser unit and the external grilles are very small and discreet, the installation is typically considered ‘permitted development’. However, for listed buildings or properties under an Article 4 direction in a conservation area, it is always best practice to consult with the local planning authority. We can provide documentation to support this process.
Absolutely. The Powrmatic Vision is the perfect air conditioning system for high-rise apartments, as all work is carried out from inside the property. There is no need for external access, scaffolding, or cranes, which makes it a safe, fast, and cost-effective solution.
The final cost depends on the model chosen (3.1kW or 3.6kW) and the complexity of the installation (e.g., wall type and electrical requirements). As a direct supplier-installer, we offer highly competitive pricing. For a detailed, no-obligation quote tailored to your property, please contact our team. We provide a full breakdown with no hidden costs.
The Powrmatic Vision can be mounted high or low on a wall. For cooling, a high-level installation is generally best as cool air naturally sinks. For heating, a low-level installation is more effective as warm air rises. We will assess your room layout and primary usage (heating vs. cooling) to recommend the optimal placement for year-round comfort.
The latest Powrmatic Vision models utilise R290 refrigerant. This is an ultra-low Global Warming Potential (GWP) gas that is highly efficient and environmentally friendly. Unlike traditional split systems that use F-Gases, the Vision's design means our installers do not require F-Gas certification, further simplifying the installation process.

His expertise was evident throughout the process, and he took great care to ensure that the unit was not only functional but also aesthetically pleasing. The AC operates efficiently and is impressively quiet, making it possible to comfortably sleep in the same room while it's running.Posted on Steve NashTrustindex verifies that the original source of the review is Google. With the heatwaves in summer our bedroom was unbearably hot at night, so my wife and I looked around for a solution. Our house is in a conservation area so we wanted to avoid having a big air-conditioning box on the outside. We came across CoolSleep where the unit is on the inside. We got a quote, which was less than we expected, and Dan and his assistant came to install it. We are very impressed with how neat and quiet the unit is, which can either cool our bedroom, or provide heat if needed. The controls are simple to use. Dan did an excellent job, he gave us various options re exact location, finish, etc., and cleared up very well. We certainly recommend CoolSleep.
