Help with thermostat for old boiler driven hot water tank
My brother in law has an older home in Bernardsville nj where the hot water for the the house is done using the houses boiler and a hot water storage tank. It seems that the thermostat for the hot water is not working, no matter the setting on the thermostat the hot water is always scalding. I have a poor shot of just the thermostat, I can get more pics if needed. Is the thermostat replaceable or should I advise my BIL to get a traditional hot water heater?
