Keston Boilers Guide

Hello,

My two years Keston Combi C55 boiler is providing extremely hot water. I am unable to take shower. Does someone know the reason behind this issue? Should I call an engineer or replace the boiler?

Thanks

William

Hi William, you do not have to replace your boiler. If water is coming out extremely hot, then it is likely to be the thermostat issue. If the central heating system is using a hot water cylinder or tank, then cylinder thermostat is a culprit. I am sure new thermostat will solve this heating issue. Nevertheless, if water is coming out too much hot from shower then, there is nothing wrong with the thermostat. The sealed units in the showers are susceptible to failing. If sealed units have failed while setting in the hotter set, it is likely that they are badly stuck there. Therefore, you have to replace the shower-sealed units.
