Unvented Cylinders
Unvented Cylinders

Unvented Hot Water Cylinders suppy mains-pressure hot water throughout the home - achieved by connecting the cylinder directly to the rising main. Unvented Cylinders can be heated Directly using an immersion heater, or Indirectly (but not for use with a Solid Fuel Boiler). There are no water storage tanks, feed and expansion tanks or open-vent pipes. An unvented cylinder instead uses a diaphragm inside a pressure vessel on top of the unvented cylinder. If this vessel fails an expansion relief valve protects the system by releasing water via a discharge pipe.Unvented cylinders are increasingly specified and are becoming very popular. They come in various capacities suitable for small homes to large family houses. BHL supply a wide variety of Unvented Cylinders including the ever popular Heatrae Megaflo HE with its 25 year warranty. The Santon Premier Plus range offers a cheaper alternative. We also supply the Range Tribune and various Solar compatible cylinders
