Heat Only Boilers

Heat only boilers (also known as 'traditional', 'conventional' or 'regular' boilers) provide central heating and hot water but don't include an integrated hot water storage tank. Heat only boilers work by heating water directly from the mains or a cold water tank and circulating it through a system of radiators or underfloor heating. Here, you'll find heat only boilers from reputable suppliers, with a variety of sizes to choose from.
