An open vent boiler - often described as a traditional boiler - is the perfect choice for homes already with a heating and hot water system with a separate hot water cylinder. Traditional boilers also need a header tank to feed the hot water cylinder and an expansion cistern in the loft. They're the practical option for homes with more than one bathroom where plenty of stored hot water is needed or in low water pressure areas. Again, these boilers work with solar water heating systems for environmentally friendly hot water and further cost savings. Band A Condensing Boiler (boiler only).
