We moved into our house a year ago and since then I have been monitoring the consumption.
For us it is 7-8 Kw/h per day, even in midsummer. When we are completely out of the house, it is about 6 Kw/h. That means about 2000 Kw/h per year at currently €0.26 / Kw/h going to waste. 1-2 Kw/h per day for hot water seems about right….
With an annual consumption of about 6000 Kw/h, the “background noise” corresponds to one third, or if you assume that we only needed 4000 Kw/h, then it is 50% additional consumption.
Just for comparison:
Since Saturday the radiator in the bathroom has been running continuously at 2.5. That costs us about 4 Kw/h per day.
Even setting the heating completely to standby does not help.
I wanted to ask this question here already and I am happy about any clarification.
I guess it is simply due to the principle, since the carrier liquid is continuously pumped through. And then there are heat losses in the transfer station.
I would of course love to turn that off but actually have little hope.
It’s a pity, because 40 Kw/h /sqm/ would really be something for the year 2000.
And we also pay an additional €45 basic fee per month.
