Hi all,
I've been trying to get the hot water temperature in my new flat (bought) under control as it's been scalding hot since we moved in.
My initial theory is that the cylinder thermostat was broken, so I've replaced that twice now and it still seems far too hot when set at just 60 on the thermostat valve - very painful to touch, like from kettle.
The tank is fed from a Gas boiler with a fully pumped system. The actuator and pump are working fine. It's a British Gas branded system, which is a re-badged Drayton system. The thermostat is a Drayton HTS3 (original was labelled BG CS1).
The thermostat is seated 1/3 up the tank and the area of insulation has been well cut away to expose the copper. The area it sits on is very hot to the touch when the heating has been on for 40+ minutes. Yet it only seems to 'click' off when I turn the control down to about 50...
The HW only comes on for 30mins in the morning and a top-up of 20mins in the evening. The Gas boiler thermostat is turned down to just '1' on the dial.
I can't believe I've had 2 duff thermostats in a row - is there something I'm missing, what else could cause the hot water to get that hot?
I live in London - could the tank be scaled and insulating the water from the thermostat? Does that happen?
I think I need to get a thermometer too and test the temperature more objectively...
Anyway any tips on why I keep getting very hot water from the taps would be much appreciated.
Cheers,
Chris.
