Central heating

[PatriciaH]

Getting heat from rads but hot water coming through tepid? its a combi boiler... what could be the problem.. thanks

I know it is cold but I would turn central heating off for a few hours.

Then ,when rads and water theirin are cold turn on hot water tap.

The boiler should fire up and keep on as long as hot tap is running.

If boiler fails to fire I suspect the cold water flow detection switch in the boiler is faulty.


It would be difficult to detect a problem with the boiler alight feeding the rads.

I have a combi boiler too Patricia and it has 2 control knobs for heat selection , seperate one for the taps water and another for the radiator water heat , dials numbered 1-10.
