Heat pumps work by collecting heat from the air or the ground in or around your building, it is then converted to produce hot water or to heat the building. If correctly designed and installed they can over time represent huge savings in your energy bills.
There are lots of different types of heat pump – below are details of the systems we offer to our customers.
From the Ground
There are several ways of collecting energy from the ground, even on the coldest days there is still heat kept below ground which can be used by the heat pump system. Typical installations involve either digging a bore hole straight down into the ground – which is a good solution if space at the property is limited, or by laying collection loops in the ground horizontally – best if the property has a large amount of land such as fields or a large garden. If your property has a lake or river attached to it we can offer heat pump systems to collect energy from these too.
How a Ground Source Heat Pump Works
From the Air
There are two types of heat pumps which collect energy from the air : ‘Air to Water’ and ‘Exhaust Air’ systems. Air to water systems take heat from the air outside the building and use it to heat water for the property, Exhaust air systems take excess warm air from certain rooms in the building – such as kitchens and bathrooms and use it to run the heat pump system to provide heat for the rest of the house. Exhaust air systems also provide a ventilation facility for the property in the way they work.
Unlike Ground source Heat pumps, air systems cannot provide large amounts of energy all year round, so would need a supplementary system for the coldest parts of the year.
