About the range

The high quality, stainless steel uniSTOR cylinder is a hot water storage facility, ideal for social housing and new build developments with a new or existing sealed system or open vent boiler. uniSTOR cylinders are unvented cylinders which means they can operate efficiently under higher pressures and work in perfect harmony with all Vaillant domestic boilers.
