System Boilers
A system boiler is a boiler that directly heats your central heating system and hot water for a storage cylinder, whether it’s an unvented, stainless steel cylinder or a traditional copper cylinder. Most of the important parts of the hot water and heating system, such as the pump and expansion vessel, are built in on a system boiler – making it quicker and cleaner to install. It also means you get a faster response to demand for heating and hot water, plus you don’t need to have a feed and expansion tank in the loft. Here at Mr Central Heating we stock a huge range of system boilers from all the leading manufacturers, including Vaillant, Potterton, Baxi, Worcester, Glow-worm and Vokèra – at the lowest prices in the market.
