A combi boiler is a combination of a heating boiler and instantaneous water heater. Hot water is taken straight from the mains, rather then a storage cistern. Contained within the boiler are all the controls required to achieve this function together with a pump and expansion vessel. The expansion vessel absorbs water expansion in the heating system, as is required for a sealed system. A temporary link is provided to connect the heating circuit direct to the mains cold water for the purpose of filling it. This link should not be left permanently in place as it would then be in contravention of the Water Byelaws.
