I have a regular condensing boiler (Greenstar 12Ri), open vented system with HW tank. I am trying to increase the temperature of the water, current water temp is 60 deg.
I've turned up the thermostat on the boiler to maximum (instructions say this should be 82 deg. I've also turned the HW tank thermostat to 70 deg.
I've run some tests and cannot get the water any hotter than 60 deg.
When I turned the themo up on the HW tank, I heard it click and watched the actuator valve open. The boiler is the first device to turn off (green light goes off), this leaves the pump and actuator valve open.
I would have expected the boiler to be the last device to turn off (i.e. after the actuator has closed because the HW thermostat has told it to). My theory is that something is wrong with the boiler themostat but will be the first to say that I don't fully understand how the whole system works.
Does anyone have any advice or suggestions.
Why changing temp? Diagnosing problems with Trevi Boost Shower.
Thanks James
