What Is A Combi Boiler?

Combi boilers are essentially high efficiency water heater and central heating units, which means that they can heat your home and provide hot water, without the need for a separate water tank. They tend to be more compact than other central heating systems, as they combine these two household functions into one appliance.

The Pros and Cons Of A Combi Boiler

If you are considering replacing your current boiler with a combi boiler, or moving into a house with one, it is important to know the pros and cons of these systems.

In the UK, Combi Boilers are the most popular type of boilers to be installed for various reasons.

Pros Of Combi Boiler

Why?	How?
More Efficient	Combi boilers are highly efficient when compared to older boiler models. In fact, replacing your boiler with a newer combi boiler could help you to save up to £300 a year on your heating bills.
Cheaper	Combi boilers are far less complex than traditional heating systems, which means that installations tend to be cheaper. It is also easier to find replacement parts if a problem occurs.
Quicker	With no water tank to heat up, combi boilers can provide an unlimited supply of hot water on demand. No waiting time!
More Compact	As there is no need for a separate water tank, combi boiler systems take up much less space than conventional heating systems. This makes them ideal for homes that have limited room.
Safer	The cold water from a combi boiler system is always safe to drink as it is fed directly from the mains. However, this is not always true of traditional systems, which may store cold water in a tank before it is piped through the house.
Better for selling purposes	As combi boilers tend to be more efficient than other boiler types, this can be a selling point if you are looking to rent or sell your property. This will also show on the Energy Performance Certificate (EPC).
Cleaner	Central heating systems with a combi boiler generally have less sludge build up, because the water is piped directly from the mains and not kept in a tank where it can accrue rust and debris.
Easier to service	The popularity of combi boilers means that a majority of boiler engineers are trained how to repair and service them. This makes it easier to find qualified engineers in your area.

Cons of Combi Boiler

Despite the popularity of combi boilers, there are several issues that you should bear in mind when considering replacing your boiler.

Why?	How?
Mains Pressure	To ensure that your combi boiler is working properly, you need good mains pressure. If you are having a new boiler fitted, you should check what the mains pressure in your area is before you go ahead with the installation.
No Immersion Heater	As there is no water tank, if your combi boiler breaks down then you will be left without hot water as well as central heating (unless you install an electric shower).
No Power Shower	You can’t have a power shower with a combi boiler, as the water pressure is set by the pressure level at the water mains.
