The Telford Tempest 250 L Indirect Unvented Cylinder is a high-quality stainless-steel hot-water storage cylinder designed for modern UK heating systems. It’s engineered for use with a boiler (gas, oil or similar) as the primary heat source and provides mains-pressure hot water at high flow rates for taps and showers throughout medium to large homes.

Built from Duplex 2304 stainless steel, the Tempest cylinder offers excellent corrosion resistance and long service life, making it an ideal choice for reliable domestic hot-water storage. The cylinder is fully insulated with high-density foam to minimise heat loss and improve energy efficiency.
