I would be more interested in your heating load calculation including flow rate. Why does one plan something like this with an undercoverage in every room?

I also tried that with the controlled residential ventilation when I couldn’t explain the operating behavior of the heat pump at the beginning of January. The humidity rose directly to 60%. :cool:

I posted something about that in the last 2 pages. There you can see the design (not optimal) and the flow rates. They are all actually around 0.8 l/h plus or minus 0.3 depending on the room. The undercoverage only occurs because a reference value of -16 degrees was used for the design, which we never really have except this year. In addition, a partial wall heating was installed in the bathrooms and the installation spacing was made even closer. So countermeasures have already been taken. The correct approach would have been to make a new calculation and then execute it correctly according to the planning. But you know the experts...

Consumption Air-Water Heat Pump Dimplex LA 9S- TU ca. 180sqm, southern BW at approx. 650m elevation House temp. 23 degrees 01.01.21 - 11.02.21 Heating + hot water Total consumption 762KW Daily consumption approx. 18KW Ceiling heating on the ground floor, which will not be as efficient as underfloor heating.

Yes, I also think that's good, but one must consider that it was also 2 degrees warmer there than with us and he heats "only" 180 m².
