Harlequin launches "ground-breaking" Harlequin HeatStream cylinder

Harlequin MFGhas launched the Harlequin HeatStream, a revolutionary square, plastic, vented system that delivers main pressurised hot water.
A ground-breaking advancement in hot water storage, the product is a hybrid incorporating many of the advantages of Vented, Unvented and Thermal Store cylinders.
The Harlequin HeatStream range is the result of a collaboration of industry expertise in both the rotational moulding of plastic tanks, and pressurised hot water storage systems.  It is a refreshingly simple system that allows main pressurised hot water to be produced from a vented system. It is designed with a large surface area DIN 316 Stainless Steel Heat Transfer Coils for both the heat up and hot water draw off.  These coils transfer heat through the heat transfer fluid (static body of water) contained in our durable polypropylene inner tank.
