Construction The Elson cylinder range is constructed from strong and lightweight Duplex stainless steel to allow ease of handling on site, whilst offering exceptional corrosion resistance particularly in aggressive water areas, compared with some forms of stainless steel and glass-lined steel. With no sacrificial anode to replace regular maintenance is kept to a minimum. Every Elson cylinder is tested to 15 bar in its manufacturing plant, giving flexibility whether in a domestic or commercial application. Foam insulation measuring 50mm (CFC/HCFC-free ODP zero) is available on all models to give improved insulation standards. Our cylinders are finished in modern and robust white plastic-coated corrosion-proofed steel, cased with grey high impact thermoplastic top and bottom mouldings. Performance Indirect models are designed to offer high output coil-in-coil heat exchangers rating from 12.5 to 19kW allowing high efficient transfer of energy whilst its position in the base of the cylinder maximises the amount of hot water heated, and the cold water controls design delivers good flow rate performance. The Elson cylinder range gives mains pressure hot water for a balanced supply to showers and mixers without the need for a shower pump. Installation Designed with the installer in mind all plumbing and electrical connections are located easily to give maximum access. Plumbing connections are 22mm compression. Capacities range from 120 to 300 litres on the standard models and 190 to 300 litres on the solar models. With no cold feed cistern required the cylinder can be installed in an airing cupboard, loft, cellar, utility room or even in a garage. 25 YEAR GUARANTEE MADE IN THE UK 3
