TELFORD COPPER CYLINDER available in 2 variations Direct and In direct.
A Direct copper cylinder is suitable if your only heat source is electricity (heated by an immersion heater) and/or a back boiler. An immersion heater boss is supplied in the top dome of the cylinder as standard and we also supply 2 x 1" direct connections (flow and return) if you are connecting a back boiler. If you are only using an immersion heater these need to be blanked off.All copper vented cylinders are manufactured to BS1566 and PartL1B specifications as well as being fully ERP compliant.
Designed to be linked to a remote heat source, such as a gas or oil boiler. The water within the central heating system is heated by the remote heat source and is passed through the coil in the cylinder. As the primary normally operates at around 80°C, the heat is exchanged into the cylinder and warms the domestic hot water.
