Hello,
we currently do not heat yet, but we feel that the base consumption of our heat exchanger is too high. It also releases a lot of heat.
How many kWh are normal in this case without drawing any hot water?
The boiler is currently set to 60°C (140°F) due to concerns about Legionella.
Thank you very much for the information!

Hutchinson1238 Nov 2022 21:58We moved into our house a year ago, and since then I have been monitoring the consumption.
For us, it is 7-8 kWh per day, even in the peak of summer. When we are completely away from home, it drops to about 6 kWh. That means around 2000 kWh per year, currently at €0.26 / kWh, are basically wasted. 1-2 kWh per day for hot water seems realistic...
With an annual consumption of about 6000 kWh, this "base load" accounts for one third, or if we assume we only need 4000 kWh, that means a 50% additional consumption.
Just for comparison:
Since Saturday, the radiator in the bathroom has been running at 2.5 (setting) continuously. That costs us about 4 kWh per day.
Even having the heating fully on standby does not reduce consumption.
I wanted to ask this question here already and would appreciate any clarifications.
I estimate that this is probably inherent to the system, as the heat transfer fluid is constantly being circulated. This naturally leads to heat loss in the heat exchanger unit.
I would love to turn this off completely, but I don’t really have much hope for that.
It’s a pity, since 40 kWh per square meter would be quite impressive for a building from 2000.
Additionally, we also pay a fixed base fee of €45 per month.
