The external unit in domestic air source heat pumps is no larger than a washing machine, and can be located anywhere where there’s a decent flow of fresh air (or ambient air flow) and a bit of breathing room. To keep installation costs down, the heat pump can be connected to the buffer tank inside via an existing flue (a vent or outlet for steam on the outside wall of your home), but if you’re worried about aesthetics, the box can also be wall mounted to the back of the garage or hidden away in the garden.  As part of our Home Assessment Report we will always clearly indicate where we would propose siting the unit. 

In terms of power output, there are a few options to choose from depending on how much heat you require, but 5kW, 8kW and 12kW systems should cover the demands of most households. As a guide, it generally takes 1 Kilowatt of heat to warm every 10m² of a house (subject to insulation and heat loss).
