Boiler Types Explained

Combi Boiler

System Boiler

Regular Boiler

Combi (or combination) boilers are the UK's most popular type of boiler for gas central heating and domestic hot water.

A Combi boiler only heats water when a hot tap or shower is turned on, ensuring maximum efficiency. There is no need to find space for a water storage cylinder or have a tank in the loft.

A system boiler pumps hot water to the radiators and a sealed hot water storage cylinder. Most major components of the heating and hot water system are built into the boiler, making installation easier, tidier and more efficient, and also simplifies servicing.

System boilers combine high efficiency and high performance with exceptional 'green' credentials.

Heat only boilers are also known as 'regular' or 'conventional' boilers. If you are replacing an old boiler and have a small expansion tank and a larger cold water storage cistern in your loft space, you probably already have a heat only boiler.

Heat only boilers are usually installed on an open vented system. The system will usually comprise two tanks in the loft.

Fair, Honest and Do a Good Job

After one local boiler company took one look at my leaking boiler and said I needed to replace it, Synergi took a look, identified the problem, fixed it and gave it another year of life. When it finally gave up they installed a new one efficiently and for a good price. Trust is hard to find it tradesmen so Synergi was a good find...
