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?

And if not, you just come back after 3 weeks and manually start the hot water production.
With ours, this is done by pressing a button. Then I heat the water to over 60°C (140°F) and that’s it.
Why run the weekly anti-legionella program if you’re not around anyway? I think it doesn’t really matter if the water in the buffer tank stands for 1 or several weeks, since heating to 60°C (140°F) kills everything regardless of how long the "soup" has been sitting.

If you look at it that way, the discussion is actually irrelevant because maintaining that small amount of hot water at temperature for a week won’t break the bank. Storage losses are said to be around 1-2 kWh per day, which translates to about 10 cents per day.
Like I said, it’s just laziness.
