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

2019-12-19 21:26:51

Is it possible that heating was not active at the reading time?
Of interest is the flow and return shortly before the end of a heating cycle.
How long does the pump heat now per heating cycle?

Where can I see how long the pump heats on average per cycle?

Pull data log via USB and read the graph in Opendta (google) Curve VD1 mostly

Ok, attached are the data from this morning. The heat pump was just running in the final stages, so I could only read the basement. When I came upstairs, it was already off. Volume now only a total of 1059 per hour, is that too little for LAD9? The temperatures now seem to be okay. However, I adjusted the heating curve again yesterday late evening to: 29-22-0. Because, for whatever reason, the living area and the large bathroom were only at 20.6°.

The spread of almost 10K in the bedroom is good, the temperature is already dropping by 1.5K. The high hallway temperatures are surprising despite a high spread and low flow. Maybe the screed needs another day or two to retemper. I would wait until tomorrow for now. I still see the main bathroom critically, it seems to be undersupplied with the underfloor heating. You will have to add heat if necessary. Have you loaded "Opendta" meanwhile? What heating load does your house actually have, heating only without hot water?

Surprising are the high hallway temperatures despite a large spread and low flow. Maybe the screed still needs one or two days to re-temperature itself. I would wait until tomorrow for now. I still see the main bathroom critically, it is apparently under-supplied with the underfloor heating. You will have to add heating if necessary.
Have you downloaded "Opendta" in the meantime?

The hallway thing surprised me too, but exactly, I will wait and see the next 24 hours.
Where do I get the heating load of our house?
I am downloading opendta now

Remember that the hallway usually provides access to all the rooms. No matter how much you regulate, it never really gets cold there. It is "worst" right at the HKV.
