Hello!
I'll start.
Heated area 200m2 (2,153 sq ft)
KfW 55 standard
Mechanical ventilation with heat recovery
Current outdoor temperature 6°C (43°F)
Heating energy consumption including hot water 35 kWh
Electricity consumption 9 kWh
COP 3.88

I am now going to build a light well cover for these situations and then place it on top.Then you can almost be thankful for the warning shot last night.Zaba12 schrieb:
Bookstar can handle a bit of teasing. The few cents difference in outdoor temperatures is alright. Although I can’t really distinguish between my on/off heat pump and the modulating components here. What is the power consumption of your modular heat pump at the lowest setting?
Also, the temperatures plus rain are really benefiting the garden that was established last year.Nibe F730 at lowest compressor frequency (20 Hz): approx. 260-280 W4lpha0ne schrieb:
NIBE F730 at the lowest compressor frequency (20 Hz): approx. 260-280 W Hm… I find that quite manageable. During the transitional season. With a storage tank and photovoltaic system, you wouldn’t need to manually increase the return temperature for 280 Wh. At least, that’s how I see it if I had a modulating heat pump.

In June, the heat pump finally stopped heating and only produced domestic hot water.
The amount of heat generated in June was 124.4 kWh, with electrical consumption of 35.1 kWh (29.4 kWh for the compressor and 5.7 kWh for electronics/circulation pump). COP=3.54.
I am satisfied with that and now looking forward to the next heating season.

I also have to admit that we take a lot of showers.
I also find the amount of heat surprisingly low, especially considering that the heating system ran intermittently. I would also be interested in basic data regarding hot water consumption (limit temperatures, storage tank size, number of occupants, circulation yes/no).
