Hi all,
looking for some advice..
I had to drain my central heating system to change some valves on some rads - all went fine, the rads are all heating up fine after I refilled the system.
But now heres the thing....
When I turn on hot water the boiler does nothing, and does not kick in, and as a result we have no hot water.
But heres the other thing....
If I turn on both heating and hot water, we get hot water.
Any idea whats happed
ps....there are 5 valves in the loft/by the boiler/tank. I assume these are valves that need draining once in a while to let out air, I have done this several times and there seems to be no more air comming out of them. All rads also seem to be air free too.
