Sometimes we have hot water, sometimes we don't! ferroli 80e boiler?
Help! Our boiler sits at about 2 bar of pressure. We have had problems with hot water going cold occassionaly, but recently we have to keep re setting the bolier to get anywhere, and today it is making very loud clanging sounds every hour or so. There is no air in radiators, can anyone advise please?
