The Telford Tempest Direct Unvented Hot Water Cylinder 90L (TSMD090) is a compact, floor-mounted cylinder designed for properties with modest hot-water requirements and an electric heat source. As a direct cylinder, it heats stored water using two factory-fitted 3kW immersion heaters rather than a boiler. Its 90-litre capacity and vertical format make it a space-conscious option for suitable homes, apartments and other installations.
The cylinder is made from duplex stainless steel and has a white outer casing. Listed dimensions are 750mm high and 510mm in diameter, with an empty weight of 30kg. The stated standing heat loss is 66W and the ErP rating is C. Check the required hot-water capacity, access route, dimensions and system compatibility with a suitably qualified installer before purchase.
