Heat Pumps

Heat pumps are designed to move thermal energy opposite to the direction of spontaneous heat flow by absorbing heat from a cold space and releasing it to a warmer one or vice-versa. A heat pump uses some amount of external power to accomplish the work of transferring energy from heat source to output.
Air Source
Air source heat pumps use the heat in the amibient air to provide efficient heating and hot water at air temperatures as low as -25°C. Installation can be indoors or outdoors and with the UK having mild winters, excellent performance levels can be reached. Another feature associated with the product is low installation costs and minimal space requirements.
Ground Source
The earth has energy from solar radiation and rainfall and a ground source heat pump extracts this energy either horizontally or vertically. Although more costly to install, higher efficiency is usually achieved regardless of seasonal variations in temperature.
Air to Air (Gas absorption)
An all in one heating and cooling system which works in reverse to a refrigerator providing low cost heating. The extremely efficient process can produce five times more heat than the electrical energy it uses and the added benefit is the process can be reversed in the warmer months to provide cooling air.
