I have filled the system up as instructed in man instructions i have reset. It fires up but cuts out just when the hot water is about to pump around the system then it throws up F37 again.The room stat has not yet been installed how ever the timer is wired up the bridge is still in place. can you advise look forward to your swift response.
I have a Feroli domicomact 24b boiler, and it was switched off as I am having a new kitchen fitted. Turned the boiler back on, have hot water but no heating??
