Most homeowners get the wrong installer
Heat pumps work brilliantly when designed and installed correctly. The problem is, most aren't. A poorly designed system runs at higher temperatures, costs more to operate, and never reaches the efficiency it should. You need an installer who guarantees the result — not just the fitting.

Why does Heat Geek use Vaillant?
The aroTHERM is one of the most efficient, quietest, and most reliable heat pumps in the UK. R290 natural refrigerant, 150+ year track record. It's the heat pump we're willing to guarantee.
What about Daikin, Mitsubishi, or Samsung?
Reputable manufacturers, but we specialise in Vaillant. Deep expertise in one platform means better designs, better installations, and better outcomes than trying to be generalists.
Are Heat Geek installers MCS-certified?
If you go through Heat Geek, we will be your primary installer and we are MCS certified and TrustMark registered. We oversee all installations which is why we can provide our performance guarantee. All Heat Geek installers are trained to Heat Geek’s technical and customer service standards.
How quiet is the aroTHERM?
From 29 dB — roughly a whisper. Well within UK planning noise limits, even close to neighbouring properties.
