A combi boiler, also known as a combination boiler, provides heat for central heating and domestic hot water upon demand. With a combi boiler heating system you do not require feed and expansion tanks in your loft space or an unvented cylinder, therefore saving space.
Water is fed from the mains supply which maintains high water pressure and is heated instantly. However if you live in a low water pressure area, or have multiple bathrooms, a combi boiler may not be suitable. We always advise that you seek advice from your Gas Safe Registered engineer.
