Heat source
What makes the heat.
Three ways to heat a home, and we fit all of them. We lead with heat pumps because for most homes they are the right answer and the grant money is behind them — but the right answer for your home is the one the survey points at, not the one we would prefer to sell.
Air source heat pump
What we recommend for most homes, and what the grant money is behind.
3–4 kWh
of heat per kWh of electricity
A heat pump does not make heat, it moves it — taking warmth out of the outside air and concentrating it into your heating system. That is why it returns several units of heat for every unit of electricity, where a boiler can never return more than the one it burns.
Efficiency depends on the temperature it has to reach, so the emitters matter as much as the pump. We design the whole system together: a room-by-room heat-loss survey first, then the pump, the emitters, the cylinder and the controls around the numbers that survey produces.
Air source heat pumpsSuits
- Homes where the fabric is reasonable or can be improved
- Anywhere off the gas grid currently on oil or LPG
- Homes with, or willing to move to, larger or low-temperature emitters
- Anyone pairing heating with solar and battery
Worth knowing
- Needs space outside for the unit and usually a hot water cylinder inside
- Costs more to install than a boiler before the grant is applied
- Works best at lower flow temperatures, which can mean changing emitters
The other half
What delivers it matters just as much.
A heat pump feeding the wrong emitters runs hot and costs more than it should. The emitters set the flow temperature, and the flow temperature sets the efficiency — so we design both together rather than one after the other.
Not sure which you need?
That is what the survey is for. A room-by-room heat-loss calculation tells us what your home actually needs, and the answer comes back with the numbers behind it.
