Hi We have had a Vigas boiler to provide our heating and hot water in our 5 bed detached house for a few years now and still we have not managed to master the damn thing! We seem to have it working fine for a few weeks then it starts playing up! My poor husband & father in law are at their wits end as they keep splitting hundreds of logs but the boiler only produces luke warm radiators. Also it keeps switching itself off! The temperature reached 80c then as soon as the heating is turned on the boiler heat drops to 40 or 50c and switched off! Has anyone got a Vigas boiler and had problems or does anyone have any suggestions? So far we have regretted buying the boiler which in total has cost us around £10,000!!
