Air-water heat pump current consumption and data

AIT

That is the favorite heat pump in the other forum.

That you have such low hot water consumption with 46 degrees hot water and 3 degrees hysteresis is surprising. They say 1/3 of the total consumption. So either you never wash :) or your building is still really extremely damp.

The heat pump currently runs for 14 hours continuously and consumes about 8 kWh.

Used 3.5 kWh today and 19.38 kWh heat quantity.

Hm, so what now? Isn't "currently" today?

Hmm, what now?
Isn't it today currently?

The 8kWh was yesterday :) For today, the meter shows 3.5kWh.
How do I know how low the heat pump can modulate?

Can you set an AT damping?
I am currently trying a 24h average of the temperature for exactly that reason.
In combination with a slight increase during the day and the storage heater, it looks like I can quite well avoid heating at night.
At least so far, at the current temperatures.

Damping or 24h averaging of the outside temperature is unfortunately not possible with the Luxtronik controller from AIT. It would probably be the better control for my solid construction with a lot of slow storage mass and because of the cold spikes at night.
The other drawback is that I cannot limit the maximum output of the modulating heat pump, and the heat pump initially runs at full power for about an hour before it throttles down.
Have you ever measured how much advantage in the performance factor operation exclusively during the day brings?

When comparing data, one should also write down the room temperature (possibly also that of the bathroom). My neighbor consumes 1/3 less, but only has 19.5°C in the living room and bathroom, whereas I have 22°C in the living room and 23.5°C in the bathroom.

Since I reset my heat pump after every new setting, unfortunately I have no comparison values. However, last winter was certainly one of the coldest in recent years. That should not be forgotten...

No, I’m not there yet, it’s the first heating season :D I only set it up a few days ago in preparation for impending photovoltaics. But I don’t have any logs yet either, it’s all pretty much a shot in the dark.
I’ve actually had more of a problem that the heating didn’t switch back from setback mode to heating mode. Despite several K Delta T it didn’t want to start heating yet.
I suspect the "Heating power relative". It was always around 0 or even negative. I fiddled around a bit and increased the P portion in the controller, and also softened the (feigned) total oversizing of the heating a bit.
Now the heating finally kicked in today.

The other drawback is that I can’t limit the maximum output of the modulating heat pump, and the heat pump runs at full throttle for an hour before throttling down.

That’s nasty.

Did you set heating programs then? Do you let it heat at night?


Why do you reset every time? Does it delete all values for you?
Hard reset or just the controller?
