Hi,
Trying to understand how the (dual?) thermostat on my freshly installed indirect unvented cylinder (manufacturer is Joule) is supposed to be working. The thermostat is attached about a third from the bottom and let's me set the temperature between 25 and 65 degrees. It has been wired to the immersion heater, ie as long as I don't use the immersion heater (most of the time) it will be useless and the flow temperature of the boiler will control the temperature of the hot water which is not very practical (I might want a very high flow temperature if it is very cold outside but keep hot water at say 60 degrees). If I ask the installer to come back and wire the thermostat to the motorised valve of the boiler instead than this should solve this issue, but then I would not have any thermostat that would help to prevent overheating if I ever use the immersion heater.
How is this supposed to be done properly? Do I need two thermostats, one controlling the immersion heater and one controlling the motorised valve of the boiler? Or can my existing thermostat be wired to both?
Would appreciate any advice on this!
