Combi Boiler
A Combination or ‘Combi’ boiler is both a high-efficiency water heater and a central heating boiler in a single compact unit. Combi boilers heat water directly from the mains when you turn on a tap, so you won’t need a hot water storage cylinder or a cold water storage tank in the roof space.
- Compact sizes make combi boilers perfect for smaller properties
- Ideal where there is little or no loft space
- No need for a hot water cylinder allows increased living space
- No cold water storage tank frees up a loft for conversion
- No risk of loft pipework freezing
- Less pipework in the home makes installation typically cheaper
Regular Boiler
Regular boilers (sometimes known as traditional, conventional, heat only or back boilers) are ideally suited to homes that already have a traditional heating and hot water system which is linked to a separate hot water cylinder. These boilers also need a cold water storage tank in the loft to feed the hot water cylinder as well as a tank that maintains the water level of the central heating system.
Detailed below are the benefits:
- Perfect for homes where a lot of hot water is used at the same time
- Ideal where there are two or more bathrooms
- A good option in areas where water pressure is low
- Compatible with solar water heating systems for a lower carbon footprint and lower energy costs
