The het pump itself n produe domesti hot wter of mximum 55 C (50 C if outdoor temperture is low). The eletril resistne integrted in the het pump n higher this temperture. However, this onsumes more energy. Dikin reommends to set the desired DHW tnk temperture elow 55 C to void using the eletril resistne.
