DOMESTIC HOT WATER HEATING USING HEAT PUMPS


Five years ago, recommendations for designing domestic hot water heating
systems using heat pumps were published in the STASCH project: Standardschaltungen für
Kleinwärmepumpenanlagen (“Standard circuit diagrams for small-scale heat pump plant”). In
the project on “Domestic hot water heating using heat pumps” the effectiveness of these
recommendations was studied. Furthermore, optimum hydraulic circuits and control
procedures were developed based on measurements on a test installation in
Rorschacherberg (Canton of St. Gall). Using the recommendations prepared in the project, it
should in future be possible to design domestic water heating installations for detached
houses, apartment houses, school buildings, etc. – i.e. installations of any size – using
commercial heat pumps, heat exchangers and storage tanks.
