Hot water preparation heat pump

The topic of legionella and germs in single-family homes fills entire forums. There you can educate yourself and then decide which solution is best for you. The fact is, however, that a circulation program with the associated losses is an energy and cost waster.

Hello
standing water in a line is still problematic. That is why the circulation line should be flushed once a day. Those few minutes then also do not mean any real heat loss in the storage tank.
