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.
