Looking for a Hot Water Cylinder? Try the Stelflow Range


The Stelflow Range from RM Cylinders

We’ve been working, over the years, to bring together the best technology and manufacturing practices, creating the most up to date cylinders available. Our Stelflow range has grown to include storage up to 1000 litres, making it one of the most adaptable unvented cylinder groups on the market. Whether you rely on gas, oil or electricity, there is a Stelflow option for you. We also build cylinders to work with solar power and other renewables. Which cylinder should you choose? It depends on your existing source of heat and power or the energy source you’re planning in using in a refurb or new build. Here’s a rundown of the Stelflow range:

Direct Stelflow Cylinder

The Stelflow Direct is a purpose made all electric unvented cylinder, designed for properties where gas or a boiler may not be present or feasible. The cylinder is heating solely using the supplied factory fitted immersion heaters in the side of the tank.

Indirect Stelflow Cylinder

The Stelflow Indirect is the most popular unvented cylinder, built to work in conjunction with any indirect thermostatically controlled heat source such as a gas boiler. The performance from our top of the range high efficiency coil in coil inside our indirect Stelflow’s cannot be replicated by any other method.

Solar Direct Stelflow Cylinder

The Stelflow Solar Direct gives those without any form of backup heating the chance to capitalise on the benefits of solar thermal, by providing 2 immersion heaters to back the solar thermal up and provide pacification everyone has the ability to take advantage of the suns energy.  As with all the Stelflow units the Solar Direct features the coil in coil high efficiency heat exchangers.

Twin Coil Stelflow Cylinder

The Stelflow Twin Coil presents the opportunity to combine multiple heat sources into one unit, primarily designed to work with solar thermal the unit can also be upgraded with minimal additional components to accept two boiler inputs. The twin coil unit takes advantage of two high efficiency coil in coil heat exchangers for maximum performance, it is also even possible to link these two together to give one much larger heat exchanger coils.
