Air Source

An air source heat pump differs from its ground source counterpart by sourcing its low temperature energy from that in the air instead of from that in the ground.

They are sufficiently sized so that they will provide ALL of your hot water and spatial heating needs even when the outside temperature drops to -20°C or below!

Although they are not as efficient as a ground source heat pump and do not receive the same levels of RHI funding, they do benefit from having significantly less expensive installation costs.
