What problems can be caused by poor water quality?
Poor water quality can cause
serious problems in open loop systems. Your water should be tested for
hardness, acidity and iron content before a heat pump is installed. Your
contractor or equipment manufacturer can tell ynou what level of water is
acceptable. Mineral deposits can build up inside the heat pump’s heat
exchanger. Sometimes a periodic cleaning with a mild acid solution is all
that’s needed to remove the build-up.
Impurities, particularly
iron, can eventually clog a return well. If your water has high iron content,
make sure that the discharge water is not aerated before it’s injected into a
return well.
