Combination Boilers (Combi Boiler)
The combi boiler is by far the most popular boiler in the UK, providing heating and Instant hot water on demand, this in turn means that you only pay for the water you use as you are not heating a full cylinder of water just to use a small amount of hot water.
Making it one of the most efficient and liked type of boiler.
What is a combi boiler?
- Hot water at mains pressure at the turn of a tap
- A self-contained unit without the need of a separate hot water cylinder
- Size ranges to fit the smallest of flats to the largest of houses
- Energy saving trust advises the combi boiler for households with a low demand of hot water
The system boiler is better suited to the larger household that has a higher demand for hot water while also providing central heating, the system boiler requires a hot water storage tank this allows the boiler to provide a higher flow rate of hot water meaning more than one tap can be used at once.
What is a system boiler?
- Provides hot water to more than one tap at the same time
- More economical to run
- The central heating pump and expansion vessel are held within the boiler
- Sizes to suit all size properties but better suited for the larger property
- Recommended by the Energy Saving Trust
Coventional/Heat only boilers
