Water-to-water Heat Pump
17
Borehole fo Pumping the Water (Well)
Water from the underground that is needed for the operation of the water-to-water heat pump is
pumped from the well (borehole) The quantity of the groundwater must correspond to the heat
pump flow rate. The quantity of the ground water, reliability of the source and quality of water
largely depend on geological characteristics of the area; therefore make sure to verify all the
characteristics before making the borehole.
The depth of the borehole depend on the availability of the water source.
Required water pureness
Instal a filter at the heat inlet source on the heat pump to prevent impurities and protect the
evaporator against eventual damages. During the first months of use, the filter should be cleaned
more often. Once the amount of impurities is reduced, the cleaning intervals may be longer.
The underground water must not contain elements that could cause deposits in the heat
exchanger. To prevent depositing of iron in the heat pump system, the uppper limit value is for Iron
< 0,2mg/l and Manganese < 0,1mg/l. Before starting to use the water from the well, send a water
sample to the laboratory for an analyses to make sure the water quality corresponds to required
values. This will reduce the malfunctions to the heat pump system caused by impurities in water.
Use of surface water or salt water is not allowed.
