AQUAFLOW THERMAPAVE utilizes the voided subbase of the AQUAFLOW system to generate energy. This allows the transference of heat into buildings during cold periods and out of the building in the summer months.
There is an ambient temperature in the sub-grade area of 10 degrees. It is the temperature differential between the loop and the ground that creates the energy produced within the refrigerant that affects the heat exchanger (GSHP).
The ground source heat pump acts in a similar manner to a refrigerator. A series of collector loops are set horizontally within the sub-base. It is the refrigerant (water with a brine solution) in the loop that passes the heat to the pump. This then goes through a compressor that channels the heat into the building via under floor heating, radiators or even fan coils.
The pump will be powered by electricity. However, this use of electricity is mitigated by a performance coefficient of 4:1 i.e. you will get four units of energy for every one you put in. By applying Green tariff electricity the installation offers zero carbon emissions. This sets the example for others to follow and reduces the overall use of non sustainable energy.
