Copper Grade 3 vented indirect twin coil hot water storage cylinder

Vented indirect twin coil copper hot water storage cylinders feature two inter-wound coils at the base of the tank. Designed to be heated indirectly by a gas or oil-fired boiler suitable for both gravity and pumped heating systems.
