Hi,
I would be grateful if people could help me with this. I just happened to go up into my loft this morning whilst the central heater and the hot water were both on. The shower was running so I guess the boiler was heating the heating loop.
Anyhow when I got into the loft I could see that there was very hot water going into the header tank from the overflow pipe (that comes from beloe and the airing cupboard). The water in the header tank was very very hot ?
Why is this happening, and how do I stop it ? I don't think that the steam it was generating is much good for inside the loft space.
Many Thanks
Chris
