Good morning everyone,
I wanted to ask what your house’s electricity consumption is at night when everything is quiet and sleeping, so what is running continuously?
We have a newly built house, moved in summer 2019. Our building services include underfloor heating (air-to-water heat pump), controlled mechanical ventilation (runs at full power 3 times a day for 2 hours each, then reduced), a photovoltaic system, and otherwise the usual nighttime appliances (phone charger plugged into USB outlet, e-bikes charging occasionally, 2 TVs on standby, Alexas on standby, etc.).
At night, we have a continuous consumption of about 232W (with ventilation running at reduced power and when the heat pump is not producing). I can see this in the app for the photovoltaic system. From 0:00 to 6:30 a.m. we consume about 2.8 kWh.
How about you?
Best regards

Yes, I will do that after Christmas. It is an Alpha Innotec LWD 70A-HTD.
Until now, I never dealt with the technical details or terminology of my heat pump. Until now, that is.Quick guide for the first steps:
- Fully close the bypass valve (+)
- Turn all ERR settings to maximum
- Set heating curve to 27 / 22 / 0
- Set domestic hot water hysteresis to 6K, PIN 9445
- If applicable, close any existing towel radiator in the bathroom
This will solve 98% of your problems in 20 minutes.

This will solve about 98% of your problems within 20 minutes. Thanks for the feedback, I’ll get back to you later with lots of silly questions. What exactly is hysteresis and this PIN? In the pink forum, they also talk about volume flows.
How do you know how I should set my heating curve? Isn’t that something individual?
For a modern new build, it’s probably as individual as a VW Golf 😉 feel free to get in touch. The heating curve will ensure you don’t freeze or end up with overheating. I think it can still be easily adjusted slightly downward in your case.
The hysteresis here defines when warm water is produced again—specifically when it drops below 6°C (43°F) under the target hot water temperature. I’d generally recommend a target hot water temperature of 48–50°C (118–122°F), but you’ll need to test this yourself. We manage just fine with that.
Be cautious with references to other forums, as that can lead to multi-day suspensions by the admin. Speaking from experience...

If an admin isn’t confident in handling the fact that other forums exist, I really couldn’t care less.
The heating curve and hydraulic balancing will come gradually; what Jeb.. uh, Halmi wrote here is indeed the most important part.

I reviewed my heating load calculation. The volume flow rates are between 0.3 and 1.2 liters (0.01 to 0.04 gallons). Isn’t that quite low? But this is how it is set up, and it works. Only here someone once mentioned 3 liters (0.8 gallons) or so. My pump can’t even handle that.
