Utilities

well if the washing machine is on and its boiler fed (not my expertise)

its also making sure your boiler is working overtime so thats double.

but as for the thermostat in the boiler.

i highly recommend not touching it.

i have turned them down in one or two houses because i just dont need piping hot water in the summer and after i touched what was working they suddenly became tempromental.
They would trip out and do all kinds of stuff

if it works i say leave it

exactly what i thought and i thought i was being energy efficient turning it down in 2 different houses.

out of the 12 houses i had in spain i did it in 2

and those were the problematic ones.and now i just leave it alone.

With mine I have fitted a light to show when the power is actually being used to heat the water, that is in addition to the switch which just shows it is turned on..............................................

This made me smile. As a child the airing cupboard with the imersion heater was in my bedroom. This was only allowed on on certain days and my Dad fitted a bright orange light outside the cupboard so he could tell at a glance whether we were cheating his system! Happy days.
