How It Works
Vaillant have clearly been hard at work with their new range of open-vent boiler and the 38 kw, the largest in their range, is no exception. Open vent systems (also called heat only) usually have a hot water cylinder located in the airing cupboard and a cold water tank in the loft.
Because the 438 is ‘A-rated’ you can expect gas bill savings of as much as £225 each year and carbon savings of 1,265 kg of CO2 each & every year for the remainder of the life of the boiler, when compared to not upgrading.
