Copper Water Cylinders

We have a huge selection of direct and indirect cylinders from RM in stock at our branches, ready to take away same day.

Our plumbing branches hold RM Copper water cylinders in stock and can also order special sizes direct from the manufacturer.

Indirect cylinders keep the water within the boiler and domestic hot water separate, overcoming lime scale problems and allowing pumped radiator circuits to be added. Separation of the primary heating circuit and the domestic hot water is achieved by a plug of air trapped on initial filling of water within the heat exchanger inside the cylinder.

With a direct cylinder the water is heated directly via an electric immersion element, or from a remote heating boiler, which has been designed for water heating only. This system is ideal for rented accommodation due to is low maintenance requirement, or partially used properties where frequent draining and re filling by the owner is required.
