Do I need to replace my radiators?
Not always, no.
However, if you do not replace unsuitable radiators, your heat pump may not work as efficiently as possible. Heat pumps operate at a lower flow temperature to traditional gas boilers. This is one of the reasons they are so highly efficient. To maximise efficiency, heat pumps require radiators with as large a surface area as possible.
For a full guide to the best radiators for heat pumps, click here.
How much room does a heat pump need?
You will need space outside your home for the external unit as well as inside space for a hot water cylinder. Our expert team will design the best system for you and your home.
I’m planning a renovation or extension; can I still get a heat pump?
Yes!
Our team can work from plans to design your heat pump system. Get in touch today and we will talk you through the process.

Your air source heat pump is great for the UK climate.
