Hi,
I have a Potterton combi. It's heating up rads fine, but there is no hot water. Is there a simple explanation, or something I can try?
I also notice there is a knocking noise when the system comes on/off. It's been doing this for a few weeks so I don't think it's caused the hot water problem. Again, is there a simple explanation for this?
Thanks
