ᐅ Heat Pump Energy Consumption in 2019 on a Monthly Basis

Yes, it varies because the heating phase also fluctuates a lot. I will have to wait and see how it stabilizes over the next few days.

I would like to start a new comparison thread and learn about your energy consumption. I am not completely satisfied with my own figures.

KFW55
Heated area 200 m2 (2,150 sq ft), underfloor heating
Standard rooms 19°C (66°F), living areas 22°C (72°F), bathroom 23°C (73°F)
Air-to-water heat pump with central mechanical ventilation with heat recovery
Domestic hot water temperature 50°C (122°F)

Data recording only available since April 2019:

April	407
May	347
June	109
July	131
August	144
September	198
October	356

I will update the table monthly; November will be added soon, with a projected consumption of 650 kWh.

Hey, we’ve already discussed our heating system in another thread.
From 03.11. to 03.12.19, we used 639 kWh.
How would you assess that?
Best regards

There seems to be considerable potential for improvement.

That is too much. 400 would be good.

I just messaged my heating technician again to make sure he comes by next week. This can’t go on like this; it’s a complete waste of money.

This year totals about 2600 kWh. After last year with 3200 kWh, we are satisfied. However, there was a week of emergency operation included then.
The heating curve was optimized by myself last year; so far this year, I haven’t had time to adjust it. I adapted the flow rates to the calculations. I might address the electronic room regulator (ERR) this winter.
