Unvented Mains Pressure Cylinders

Known for superb longevity and durability, stainless steel is the material of choice for modern hot water cylinders. We list unvented hot water cylinders from all the big brands including ACV, Telford, RM Cylinders, Ariston, Heatrae Sadia and more.

The most common type of unvented cylinder is indirectly heated by a boiler, with direct models heated by immersions. Solar models have the addition of a solar coil. Often commonly called a Megaflo, most unvented stainless steel cylinders contain the same parts as the Heatrae Sadia model, but are available at a far better price. We advise customers not to pay over the odds for their hot water cylinder!
