Hi,
sorry it's not a car question but someone on here is sure to know.
So i have a water tank with 2 immersion heaters. I have one working and the other is spare. I have a gas boiler plumbed into the tank that i haven't yet wired up. (gas boiler runs the central heating also so that works fine etc). It is set up as S-plan.
So for the gas boiler to heat the water in the tank i need a thermostat to tell the zone valve to open etc So my question is can i use the thermostat that is in the second immersion to turn on the zone valve?
It's a fully covered tank so i can't use the strapped around tank thermostat and it seems messy to have one fitted to a pipe when there is an un-used thermostat free that sticks directly into the tank (so should be more accurate).
Is that a bad idea? against regs etc?
any thoughts?
thanks
