Stelflow Cylinders

  • 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 soley 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.
