comprehensive portfolio of products.

Providing your customers’ hot water needs, the new Zircon

cylinder range ensures the best possible performance –

powerful mains pressure showering and fast filling baths,

whilst delivering reliability and efficiency. Using the most

advanced technology available, from Duplex stainless steel

cylinder construction for maximum strength and corrosion

resistance, CFC/HCFC-free injected foam to ensure best

possible heat efficiency, primary coil and cold water controls

design giving rapid reheat and good flow rate performance.

Backed by a 25 year guarantee with on-site service support.

Being part of one of Europe’s leading heating groups,

Elson offers you first class customer service; guaranteed

specification advice on product selection and system type,

ConstructionThe 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.

PerformanceIndirectmodelsaredesignedtoofferhighoutputcoil-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.

InstallationDesigned 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.

Mainstream Packaged Solutions

Packaged solutions have become increasingly more popular as demands for savings in the time spent on site, labour costs and on-site waste have increased. The constant need to control quality, monitor specification compliance and guarantee system performance, has also increased the demand for off-site fabrication. Our packages are supplied in modular format on robust frames, so when on site every installation is standardised and easy to connect to the system. Furthermore, every package is designed to ensure that access to all components, for on-going maintenance, is straightforward and convenient.

Packages can comprise of:

• Thermalstores • Boilers • Districtheatinginterfaceunits • Unventedcylinders • mCHP • Underfloorheatingmanifoldsandcontrols • Heatandwatermetering • Electricaldistributionboards • Telephoneandbroadbandcommunications • Spaceandservicesforawashingmachine • Heatingcontrolinterfaces • Solarandgroundthermalwaterheating • Airsourceheatpumps • Firstfixrails
