Multi-Family House in Traunstein
The task was to convert the heat generation system of an apartment building to use as much renewable energy as possible. The existing gas boiler will operate as a peak load boiler in the future system.
Gas only for peak loads
The base load is handled by a WP-Max hybrid heat pump. This type of heat pump is capable of transferring low-temperature heat (at the beginning or end of the day or in bad weather) from solar thermal generation to the heat pump, thereby increasing its coefficient of performance and thus its efficiency. For this purpose, solar thermal collectors were integrated into the facade of the building as part of the renovation measures.
During the summer months, drinking water is heated primarily using solar energy, supported by the heat pump. During the winter months, the collectors and the hybrid effect of the heat pump provide additional support for the heating system. The entire generation process is monitored and controlled by the ratiotherm central controller.
