An Open Water Heat Pump system works by recovering the solar energy stored naturally in river water or open water. The water then passes through heat pumps to yield its low grade heat before being returned to the river with a temperature change of 3°C.

An Air Source Heat Pump (ASHP) can be an efficient means of saving money and saving carbon emissions if carefully designed for space heating of an appropriately designed building.

Ground source heat pumps work by absorbing heat from the ground and transferring the heat into buildings – to heat the buildings without burning fossil fuels. The heat pump itself is located in the building and works on the same principles as a domestic fridge: the heat pump in a fridge transfers heat out of the fridge and uses a heat exchanger to disperse the heat from a small radiator at the back of the fridge into the room.

A Groundwater Heat Pump system works by recovering heat stored naturally in groundwater or aquifers. The water passes through heat pumps to yield its low grade heat before being returned to the aquifer at a lower temperature.

A Ground Source Heat Pump transfers heat from the ground into buildings. Radiation from the sun heats the earth. The earth then stores the heat and maintains, just two metres or so down, a temperature of around 10°C even throughout the winter. A ground source heat pump uses a ground heat exchange loop to tap into this constantly replenished heat store to heat buildings and provide hot water. The technology used is the same as that used in refrigerators. Just as a fridge extracts heat from the food and transfers it into the kitchen, so a ground source heat pump extracts heat from the earth and transfers it into a building.
