Underfloor heating air-water heat pump. House too warm when the sun shines

13kW? For 180m2 plus basement? And then almost 1000 meters above sea level? What kind of heat pump is that, ground loop collector or brine? Can you also add your type of heat pump for comparison?

No, a Tecalor thz504 air-water heat pump (integral unit with controlled residential ventilation and heat recovery)

220m2 heating surface
Outdoor temperature on average -3 degrees
Air-water heat pump
Heating curve 28 22 0
Room temperature 22 degrees, bathroom 22, HR 1.5
Hot water 50 degrees, HR 7
Controlled central residential ventilation
KFW55

Current consumption approx. 28 kWh/day. I am very satisfied with that. Before my optimization, it was approx. 60 kWh/day. That means consumption halved

Heating curve at 25.5 22 0

Wow 25.5, is that enough in terms of warmth?

It is probably sufficient that the heat gain from the sun and from us during the day is adequate.

It's probably enough, the heat gain from the sun and from us during the day is sufficient.

That's really great!

Heizkurve 28 22 0

Hello, quick question. What do the values stand for? For me, on the heating curve you can set the base temperature (28°C), the starting point of the heating curve (18°C), the standard outside temperature (-12°C), and the maximum flow temperature (40°C). How can I map these values to, for example, 28 22 0, and are my values OK for a new building with underfloor heating?

Thanks
