Gas Combi boiler or Combination boiler domestic hot water heating systems are the most common type of central heating boilers in the UK. The term “Combi boiler” is short for combination boiler, which is used because of the way the boiler & hot water heating system is designed.
Combi Boiler Design
A combi gas heating system does not store hot water in a storage tank or canister like conventional gas water heaters. They are designed to provide instant hot water for both your taps and radiators /central heating system. A combi boiler heats water straight from the cold water mains. The cold water is fed into the boiler which contains a sensor, burner and heat exchanger, which detect and heat your water to the desired temperature. They are compact, fit in a small storage space including cupboards and are highly efficient, which makes them the most popular domestic water heater and central heating system with UK home owners.
