Warmflow DIRECT Unvented Stainless Steel Hot Water Cylinder 90 LITRE


Inc. VAT
£583.20 SAVE £169.25 In Stock

The Warmflow DIRECT Unvented Stainless Steel Hot Water Cylinder 90 LITRE is a superb example of an Unvented DIRECT hot water cylinder, and is part of a collection of Direct Unvented Cylinders from Warmflow. The electrically heated Direct cylinders are designed for instances where the use of fossil fuels is impractical / unavailable. Featuring two immersion heaters (NOT THE 90 LITRE MODEL), one heating the entire cylinder volume and the other heating a boost volume at the top, the cylinders are able to make use of the Economy 7 tariff in order to minimise the cost of hot water. If used in this way, the cylinder should be sized to provide the complete anticipated daily hot water use, thereby reducing the use of the boost element which runs on the more expensive standard tariff. Warmflow cylinders are supplied with all the necessary parts for a quick, easy, professional installation. Warmflow supply only high quality components from recognized, market leading suppliers and factory fit the temperature and pressure relief valve (T&P) and all cylinder thermostats for convenience and safety.
