Abstract
In the near future, for ground source heat pumps, compact ground heat exchangers should probably be an answer for small gardens, without expensive borehole drillings. Solar re-charging of ground loops is today a field of research in the geothermal heat pumps industry. This article illustrates the case of a residential 6kW geothermal heat pump system installed end of 2011 in the north of Italy, with a soil-water heat pump and compact ground collectors with solar re-charge. Data from system monitoring are here presented and discussed.
