Forgive me if this is a common question, but I would like some advice about my central heating system.
I can't seem to make the heating come on beyond a certain temperature. If I set the thermostat to, say, 30 degree (max), I'd expect the radiators to be on all the time (I don't think it can be that hot in any room).
Instead, the radiators stay lukewarm. The only indication I have (which may be co-incidental) is that I ran the hot water until the tank was empty, at which the hot water (boiler) started working to re-heat the water and the radiators started to get warm.
However, this didn't last that long and they soon returned to being barely warm to the touch.
I realise this isn't much to go on, but any advice would be greatly apprecaited.
Thanks.
