HI SINCE i HAVE MOVED IN MY NEW HOUSE i HAVE HAD TO PUT UP WITH HOT SHOWERS AND HOT WATER WHEN WASHING THE DISHES. i HAVE TURNED THE TEPM DIAL ON MY BOILER RIGHT DOEN BUT IT IS STILL HOT AND I CANT SEE ANY OTHER WAS OF CHANGING THE TEMP. WOULD THIS BE A BOILER PROBLEM OR A SHOWER PROBLEM ( HOW WOULD THIS EXPLAIN MY KITCHEN SINK WATER BEING SO HOT)
If the water is still getting red hot after turning the boiler temp right down, this suggests that your boiler thermostat has failed and needs changing. Do you have a combi boiler or a hot water cylinder with header tank(s)? If the latter, there may be a cylinder thermostat that you could turn down. Most systems tend to have one of these although mine doesn't.
I have had a similar problem but then realised about a week back that my immersion heater was turned on. I have since switched off the breaker switch controlling the immersion heater and now the hot water is only being heated by my boiler and thge water temp is good.
Is it normal to have the gas boiler and an electric immersion heater both heating the hot water?
