Is a heat pump suitable for my home?
Ground and air source heat pumps are extremely versatile and can be integrated into almost every home. They are extremely cost effective when replacing coal, oil and LPG systems, so remember to consider these options before choosing to install a heat pump.
Heat pumps can be integrated into most heating systems and are more cost effective in some homes than others. Before choosing to install a heat pump you should consider what type is right for your homes specifications.
Choosing the Right Heat Collection System.
Your domestic dwelling will use either a ground or air source heat pump. Ground based systems need a trench dug in order to collect the heat from the ground. A loop is then buried in the soil, and can require a lot of space, typically around 100-200 metres.
For those properties that do not have this type of space a borehole method is used, though this can be the more expensive option. This type of heat source installation only requires around 80-100 metres for a typical installation. It is not always required that there is a single borehole, and multiple shallow versions can be drilled which total 100 metres.
Many properties may not enjoy the space needed for a typical ground source heat pump, and in this case can install an air source system. Air source heat pumps do not need any ground work whatsoever so is generally available for more types of dwellings. Typically, air source heat pumps cost less to install though their efficiency tends to lower than their ground source equivalents.

Disruption and Mess.
When installing a ground source heat pump bear in mind there will be some disruption to your garden, though over time it will return to its original appearance. Once the installation is complete, the ground loop will not need excavated and require minimal maintenance.
Ground and air source heat pumps need a surge of electricity to start, so ensure your electrical supply is strong enough to maintain the stream. All our MCS accredited installers will be able to advise you on this and many systems now operate on “soft start” alternative which limits the need of the high initial electrical current. Ground and air source heat pumps are always connected to their own circuit breaker in the fuse board.
Both ground and air source heat pumps do not require planning permission before installing, however in certain circumstances air source heat pumps may require permission as the appearance of the property will change with the installation. For all terms and conditions, visit The Town and Country Planning Department online.
When living in areas of outstanding natural beauty and conservation areas etc. it’s recommended you seek the advice of your local authorities before installing an air source heat pump.
Ground source heat pumps may require consent before being installed in the properties of listed buildings.
