We're in the Cotswolds, and our Ravelli Ecotek Amalfi Boiler stove has stopped working and has a 'No pressure' warning come on. I've called round lots of local people but no one seems to want to help. Can anyone recommend anyone? The company we purchased it through used to service it yearly but have been amalgamated into another company and their head office is in Shrewsbury and they don't seem to want to help either.
