The most common type of heat pump that we install and in fact the most commonly used in the UK are air-to-air heat pumps. There are 3 main types of heat pumps, one is air-to-air which we just covered in this article and there is another called ground source heat pump.

A ground source heat pump is more efficient than air source heat pumps, much quieter and more reliable. The installation of the ground source heat pumps can be very costly due to long runs of plastic tubing that needs to be inserted around your home.

The ground source heat pumps are super eco friendly and can reduce energy needs by up to 60%. Water source heat pump is another which requires your property to be local to a water source such as a lake, river or a well, which in Northampton, we don’t see very often.
