Combination Boilers

A Combination Of Convenience, Efficiency And Performance

Combination boilers or "combi" boiler's are one of the most popular in the UK and are found in around 70% of UK homes.

A "combi" boiler combines both a central heating boiler and a water heater in a singular unit. They are both water and energy-efficient as they only heat the amount of water needed. Making it easier to save heating costs.

However, as these types of boilers heat cold water directly from the mains, water flow is reduced when two or more outlets are in use at the same time.

Advantages of a Combi Boiler

- Instant and unlimited domestic hot water
-Combi boilers are extremely efficient, with up to 90% efficiency. Heating your home is thus less expensive when compared to traditional boilers.
- Combi Boilers are compact and maximise space
- They can free up your loft space for renovation as a cold water tank is not required
- A hot water cylinder is not required
- Combination boilers are relatively easy to install and do not require much labour in comparison to sealed systems or open vented units

Disadvantages of a Combi Boiler

- Combination Boilers cannot supply more than one outlet at a time without loss of flow
- Combination Boilers often offer a slower flow rate than boilers that utilise a hot water cylinder
- Complicated setup - Combi-boilers use sophisticated processors and electrical components to function. If something goes wrong, the expense for repairing a combi-boiler is often more than for more traditional boilers. Combi-boilers can take longer to repair.
- When a combi-boiler fails, you lose both hot water and central heating

Who are Combi Boilers Good For?

- Households that need hot water at different times of the day
- Houses or flats where multiple people are not requiring large amounts of water at the same time.
Eg two showers
- This is ideal for smaller properties without airing cupboard or roof space since Combi boilers work by heating water directly from the mains, so propertiesdon't need a hot water storage cylinder or cold water tank. 
- Households looking for a very energy-efficient and affordable solution
