The Joule Invacyl Standard In-Direct Unvented Cylinder 210 Litre is a durable stainless-steel hot water storage cylinder designed for mains-pressure hot water systems. Providing 205.3 litres of actual storage capacity, it uses a 316L stainless-steel indirect coil to transfer heat from a primary heating source such as a boiler, heat pump or solar thermal system. Manufactured with an LDX 2101 stainless-steel cylinder and coated mild steel outer casing, the Invacyl combines robust construction with dense PU foam insulation to help minimise heat loss. With a 7 bar operating pressure, 10 bar maximum mains water pressure and a 25-year warranty, it is suited to long-term domestic and light commercial hot water installations.
