i have an old gas back boiler that is gravity fed for hot water and pumped for central heating. the hot water is getting 2 hot. i had a look and theres not stat on the hot water tank. i have a room stat that turns off the boiler and does the timeing. i want to know if i can fit a hot water tank stat that will turn a motorized valve so the hot water will stop heating? if i can do i need to use a three port one so i can divert the flow back to the tank or can i just put it to stop ?? the pump is alway on when the boilers running.
