Operating efficiently under higher pressures, unvented cylinders are suitable for homes with a new or existing sealed heating system or open vent boiler. Ideal for larger properties with multiple bathrooms, heating systems using an unvented cylinder can... often provide a higher level of hot water than a combi boiler. We stock an extensive selection of high quality, unvented stainless steel pressurised storage cylinders from Vaillant and UV Gold in a choice of hot water storage capacities.
