You say cylinder, we say Xylinder!

If you thought Intergas was synonymous with gas boilers you’d be right… and wrong. Since we were acquired by Rheem in 2019 we have been benefitting from the Group’s extensive Research & Development resource to develop new, more sustainable heating and hot water products. For the past two years we’ve been collaborating with DeJong, a name synonymous with hot water cylinders and also part of the Rheem group of companies, to produce an Intergas range of cylinders, which we’ve branded Xylinders. And, just like our boilers, these Xylinders are built to last.

Xylinder performance

All our direct, indirect, pre-plumbed and heat pump cylinders are made from grade 444 stainless steel (the industry standard is 2304), one of the highest grades of stainless steel on the market and unique to Intergas. Its properties are perfect for hot water cylinders as it has extreme corrosion resistance to limescale, chlorine, stress and pitting and has heat transfer capabilities. And, the heat exchanger coil, which is
smooth not corrugated, promotes rapid heat transfer and cylinder recovery.

When it comes to energy saving, the Xylinder range has a specific design feature that sets it apart from the rest: the immersion heater sits above the coil. When it’s needed, the immersion only heats up the water required, not the whole tank, so you don’t have as long to wait if you want a quick shower, and you haven’t wasted any money heating the whole cylinder.

The Features

• Manufactured using grade 444 stainless steel for extreme corrosion resistance and heat transfer capabilities.
• Smooth internal coil for superior heat transfer and rapid cylinder recovery.
• Immersion above coil saves energy and also enables rapid cylinder recovery.
• All cylinders have sensor pockets and an immersion heater.

• Easy to install as every connection is on a 30-degree plane at the front of the cylinder.
• Lightweight construction and built-in carry handle on bottom lid for ease of manoeuvrability.
• Comes with a standard G3 kit comprising expansion vessel, dual stat, PRV, inlet group, diverter valve and tundish.

PRe-plumbed Xylinders

All our pre-plumbed cylinders are manufactured in the UK at our head office in Kidderminster. They can be built to suit customers’ requirements and bespoke designs can be created for the heat pump market. All pre-plumbed cylinders come with press-fit fittings and are fully pressure tested.
