Hi,
a quick question. What do you usually do when you are away on a longer vacation? Do you turn off the heating completely? I’m mainly asking in terms of hot water supply. At this time of year, the heating is usually off anyway. But the hot water system keeps running, whether it’s powered by a heat pump, gas, or solely solar. The pumps keep running, which seems pointless when no one is home. And heating water for nobody... I don’t see the reason.
So my question is: what do you do when you go on vacation?

Maintaining 60°C (140°F) only reduces Legionella bacteria slightly and slowly. And if my boiler is supposed to reach 70°C (158°F) once a week anyway, I might as well keep it at 60°C (140°F).
