Unvented Cylinders Experience Dramatic Growth In Demand From Refurb Market

Unvented cylinder systems are now experiencing an unprecedented growth in the replacement market, as many installers recognising that a combi system isn't always the best choice. Since figures published by the Hot Water Association in 2008, showed that mains pressure hot water systems, reached close to half of the total hot water storage market, for the very first time, the growth has continued as changing demands favour the benefits offered by unvented systems. Whilst combi systems can provide an instantaneous hot water solution, very few can exceed 20 litres per minute, or cope with demand from multiple outlets. McDonald Water Storage Sales Director, Jamie Stewart, explained " Modern households are expecting their hot water systems to be capable of delivering more hot water, at higher flow rates, simultaneously to multiple outlets and with limited loss of performance." He continued, "As a result we have seen enquiries for  our POWERflow 2000 unvented cylinder rise considerably from installers, house builders and local authorities who are beginning to question the attractiveness of the combi system.  We have also seen a dramatic increase in sales of  our THERMflow Thermal Storage Unit.  This gives the benefits of Mains Pressure Hot Water at the tap, but with a Vented Store.  This type of unit is ideal for all boilers and can also be used when people have an additional Solid Fuel heat source."
