Who makes the Tesla of heat pumps?

I struggle to get my head around just how efficient heat pumps really are. They aren't just a bit better than a boiler. Energy from thin air. It’s closer to magic.

I could replace my ageing boiler with a brand new model. The upgrade might give me an extra 5-15% energy efficiency. New for old, but essentially the same thing.But a new heat pump can be 4 times better than that old boiler. It's in a different league. It's like comparing the fuel efficiency of a family car with a small lorry.

Peak heat pump performance comes from driving it carefully. It needs to run gently. It wants to ramp up slowly. It has to be in tune with the building and the weather outside. Drive it like you own it - or better, on autopilot - and it will be hyper-efficient.

I've started the process of getting a heat pump. My attention is on the software. The hardware inside many makes and models is usually more or less the same. But the controls & UX can be wildly different.

So, tell me. Who is the Tesla of heat pumps?
