  • Conventional Combi and System boiler systems explained

    The central heating portion of a combi is on a pressurised closed loop system heated by the boiler as required. For domestic hot water the mains supply is fed direct to the boiler. This means no hot tank to refill and a constant supply of hot water at mains pressure. The downside is that if more than one tap is open the water pressure can fall.
