Ground Source Heat Pump Case Study - Care Home

True Energy installs Ground Source Heat Pump at a Care Home in Mid Wales

The example illustrated shows a fairly substantial installation into a care home. The system works to transfer heat into the home during the colder part of the year and cool the home in the summer. The heat exchangers in the floor and garden fulfilling much the same task though swapping between taking and delivering heat throughout the seasons. The system also uses some of the heat to heat water.

The pipes circulate the heat exchanger fluid transferring heat to and from the mass of the soil. The conduction of heat through the soil ensures the soil nearest the heat exchanger pipe doesn't get either too hot or too cold.

The mechanics and control systems associated with the heat pump take the place of a normal boiler and carry out the function of transferring and concentrating heat depending on the settings specified by the operator. The equipment illustrated is for a substantial commercial installation.

Underfloor heating is the optimum way to use warmth from a heat pump. A heat pump will work best when raising the temperature by approximately 30 to 40 degrees. This is not enough to ensure an optimum level of warmth when circulated through a radiator system as the amount of heat transferred into the room is insufficient. However, with the lower temperatures but high volume of heating fluid being circulated, use in underfloor heating is ideal.
