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

Yes, I am still currently going through the settings, unfortunately I couldn’t be there during commissioning, the installer himself... I better not ask him ;-) and the IdM customer service guy already said he would happily come by again when he is nearby. Until then, it's better to have a look yourself :p I just wanted to know if that is basically normal. But it doesn’t seem to be necessarily common practice. I have already read individual values like heating activation time and minimum compressor runtime... it may be that there is a value responsible for that...

At AI/Novelan there was also a forced pause after the hot water preparation, which was fixed with a software update.

Then create a topic about your system so we can take a look at it, or Daniel if he has a system like that too.

So ours is completely escalating right now. At minus 8 degrees, we need 38 kWh of electricity daily. The unit has now automatically lowered the hot water from 48 to 44 degrees. It can’t manage more at the outside temperature.

Sometimes I really wish for the gas heating back, especially in winter :(

Such a heat source, which is (largely) independent of outside temperatures, would be practical, wouldn’t it? ;-)

Let it run, what you save by lowering you have to reheat again afterward.
Just because of the inertia of the underfloor heating, that's pointless.

The required amount of heat doesn’t change, but during the day it is warmer outside, which increases the efficiency.
But I would rather raise it during the day instead of lowering it (significantly) at night.

You mean plutonium?! Definitely :cool:

Just now at minus 6 degrees I triggered hot water again. It ran smoothly, after 45 minutes the system was ready. I read the power consumption, it used 3 kWh ELECTRICITY to go from 38 degrees to 48 degrees. I think that would be fine.
