Product Description


25 Year Guarantee Unvented CylinderSolar Heated Unvented Cylinder180 Litre Capacity Unvented CylinderUnvented Cylinder

The RM Stelflow cylinder is a mega flow type pressurised stainless steel hot water cylinder. A solar indirect cylinder has another coil allowing you to harness the power of an alternative heat source such as solar panels or ground or air source heat pumps. This domestic hot water tank is made in Britain to exacting standards, featuring a coil in coil heat exchanger giving high recovery rates, meaning you can run a bath upstairs and still wash up in warm water downstairs. As an indirect cylinder, when not being heated by your alternative heat source, the water is heated by your system or open vent boiler. These cylinders come with an immersion heater for emergency hot water, a temperature and pressure relief valve, a 15mm x 22mm tundish, expansion vessel and an expansion vessel hose, meaning your fitter has everything they need to complete your installation. This Unvented hot water tank is Vertical and stands 1290mm high, giving you a capacity of 180 Litres stored hot water.
