Floor heating setting - desired temperature

With our heating system, it is really simple. There are 3 outside temperatures. Each is assigned a flow temperature.

For me, it looks like this:

20 degrees outside: 22 degrees flow temperature
5 degrees outside: 30 degrees flow temperature
-10 degrees outside: 36 degrees flow temperature

The three points define a sort of linear curve with a kink.

Then certain limits can be set: the heating turns off for me at 15 degrees outside temperature. The flow temperatures above that are therefore only theoretical. Additionally, a minimum and maximum flow temperature can be set.

It should be similar with every heating system.

Junkers Cerapur. There are two rotary knobs and a menu screen. Menu screen, said the technician, just look, don’t change anything. That’s his territory. Rotary knob a controls the max flow from very little to a lot. Rotary knob b is marked with a faucet symbol and controls how hot the hot water should be. We set it to 50. I should turn it to zero from Easter until October because then the solar system should manage on its own. The heating then won’t produce any hot water at all. I’m not allowed to adjust anything else, he says. Because customers always mess everything up and then call on Sundays because the place is cold and always say, no, we didn’t do anything. Especially teachers are like that, he says. [emoji4]

There are many factors. We have a flow temperature of about 30/32 degrees at -12 degrees. Limits for a heat pump include, among other things, the heating limit at the top and the bivalence point at the bottom. The heating curve must be adjusted to each house and each system, depending on the heating load, orientation, and personal comfort temperature.

With us, significantly less would also work, but then the tiles in the bathroom wouldn’t be as nice and cozy :D

So, I have deleted it now. If she is cold now, there will be trouble here. I fear the worst. Who knows if you are not fake news.....

[emoji23] then you just upload it again. A gas boiler doesn't consume that much compared to a heat pump.
