Water-to-water Heat Pump
62
Use acid very carefully and take into account safety regulations and protection measures.
When in doubt about how to use the chemicals, consult the manufacturer or the vendor.
Heat Source System
The water-to-water heat pump must be protected against impurities. Instal a filter at the heat inlet
side on the heat pump. 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.
Required water pureness
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.
Use of surface water or salt water is not allowed. Consult your local water supplier on the
possibility of using the heat from underground water.
