Hello everyone,
we want to build with a general contractor (single-family house, approx. 136 sqm, gable roof, <=KFW70) and would like to enter final negotiations with the last 2-3. The construction descriptions each list the ground source heat pumps (brand name + buffer tank), but not in much detail. Here I would like to inquire what you would recommend in this regard.
Since brand names probably cannot be mentioned here: Set is a brine-water heat pump with a COP of 4.7 (integrated hot water storage tank of 185L). Additionally, a buffer tank, probably between 200 - 300 L, is to be used.
1. Is this combination reasonable? 2. What should generally be considered with heat pumps? I would definitely have a heat meter and a separate electricity meter installed. What else should be considered? 3. What combination would be the most sensible from your point of view (i.e., size of the buffer tank, etc.) assuming a 2-person household (both employed, possibly a child in a few years)?
Thanks a lot in advance, Lacos
