The Telford Tornado 3.0 Indirect is an unvented stainless steel hot water cylinder with built-in thermal expansion, so no external expansion vessel is required. It has an internal coil and is designed for use with a gas or oil-fired boiler as the main heat source, on either a sealed system or an open-vented system. The inner cylinder is manufactured from Duplex stainless steel and is supplied with a factory-fitted 3 kW immersion heater for back-up heat. This listing covers the standard Tornado Indirect range in 125, 150, 170, 200, 250 and 300 litre sizes.
Each cylinder is supplied with a full unvented kit, including an acetal tundish and an inlet control group, together with a factory-fitted temperature and pressure relief valve set at 7 bar / 90°C. Fittings and coils are 316L stainless steel 22 mm compression. Telford states a lifetime manufacturing warranty on the inner container and two years on components (terms and conditions apply).
