Just want to check whether this is normal. I have a vaillant ecomax combi boiler and over the weekend my wife noticed it came on when she was outside. The heating is not on yet and no taps were in use.
I have got home today and noticed it as well, it came on for a minute or so and showed 57 degrees on the display, no taps on and heating off.
