I have a Biazi (biasi) combi boiler that has been installed for around 4 years. When I switch on the hot water tap out comes hot water, but when I am trying to turn the heating on nothing happens.

We recently had a radiator off in the bathroom and put it back on and the heating has not worked since then. Could this have anything to do with it?

I know that it is not the pump and this has been checked.

Would appreciate any suggestions.

Thank you

Yes it could be the problem. The air probably had to be bled out of your system. If you do not know how to do that I recommend a ON SITE service call to sort it out.
