Power requirements of ground source heat pumps in a residential area

A study was undertaken to investigate the energy demand for space heating and domestic hot water systems as well as the electrical power requirement for heat pumps in residential dwellings. A residential area of 96 two, three and four bedrooms houses was considered. Energy demand and power requirements in old poorly insulated buildings and in new, well insulated buildings were investigated. The requirement for electrical power for the heat pumps in the whole residential area was computed. The effect of room temperature settings, hot water use, heat pump thermal capacity and building insulation on the power requirements in the residential area was considered.
