Air-water heat pump current consumption and data

But that is also very generalized.... As already mentioned, there are various comparison calculations and it depends heavily on the framework conditions and what I include in the calculation (connection costs, chimney, solar, chimney sweep, etc.) The discussion actually doesn't belong in this thread...

If the heat pump were cost-effective from the start or better, it wouldn't be subsidized at all and gas would be taxed with CO2... But, that was all off-topic now :) However, I found the comparisons in this thread very interesting.

The thread is for chatting as long as it's about heating and energy. I got 500 euros back for electricity last year because the heat pump ran significantly worse at the beginning. I am quite satisfied now but still have concerns that the devices are not that durable. You hear about expensive repairs much more often than with gas systems.

The behavior of my heat pump at these temperatures is really interesting. It's basically like yesterday. The hysteresis limit has now been reached after almost 15 hours of pause. However, the heat pump does not start immediately but the compressor has to warm up. That took about 1.25 hours yesterday. I also think hot water will be produced first today, and then the heating operation will start.

That would then be 1 heating cycle per day, since the pause comes from the heating cycle that started yesterday at 9:30 PM and ended at 4 AM. Quite weird and probably not sensible either.

I just have 25.7 degrees in the ground floor and 22.1 degrees in the upper floor due to massive solar gain, while the heat pump has been off for 8.5 hours and will probably only turn on in 3 hours because it is still 1.0 degree away from the threshold. - outside temperature currently -5.5 degrees.

I clearly see that too. That will save us through the night ;)

We are now at 145 kWh (heat) for 72 hours, which costs me about €8.70.

With my heating installer, the district heating also did not run smoothly. Either the heating curve was so wrong that it became too warm or too cold. I have now adjusted it somewhat and can still turn off the heating pump via the house control.

There are too few "freaks" around who care about that, I think >90% hardly care and still have the ERR active. It just runs on its own, as long as it's warm.
The heating engineer can slack off a bit, it has always been that way so far.... My guy also didn’t feel like dealing with interested people, extra work and no benefit. Well, whatever.

Total house consumption is now also fixed for today. Something between 26-27kWh at midnight.

On the ground floor, since everything is open, it looks like this over 24 hours with sun...

Due to the activated heating element last night combined with -20 degrees, we are at a modest 50 kWh of electricity... this produced 106 kWh of heat.
