CoilMaster
Twin condensing boiler with high hot water output
Modern living demands energy efficient boilers and enhanced building insulation has shifted the main requirement of gas consumption from heating to hot water, and in many cases the demands of the hot water service exceed that of heating. Therefore it is important to install an appliance that condenses in both heating and hot water mode, achieving the most from every kW input of gas used.
