Ground Source Heat Pump
With looped collector pipes
A ground source heat pump circulates a mixture of water and antifreeze around a loop of collector pipes, which are buried in your garden. Heat from the ground is absorbed into the fluid, then passes through a heat exchanger into the heat pump. As the ground stays at a fairly constant temperature under the surface, the heat pump can be used throughout the year.
Ground Source Heat Pump
With vertical probe
Whether a loop or probe is used is determined in part by the accessible land - If space is limited, a vertical borehole can be drilled instead. The length of the ground loop or probe used depends on the size of your home and the amount of heat you need. Longer loops can draw more heat from the ground, but need more space to be buried in.
Water Source Heat Pump
A water source or lake heat pump effectively works in the same way as a ground source heat pump. By using heat stored in the lake water and lake bed. The collector circuit is laid on the bottom of the waterway and carries heat to a waterside home. Using heat from water reduces energy consumption in an efficient way.
