Combination or combi boilers are now the most popular choice of boiler in the UK.

Unlike the convention boiler, combi boilers provide on-demand heating to your radiators and domestic hot water.

The combi boiler doesn’t require a bulky storage cylinder and can easily fit into most kitchens or storage cupboards, making them the ideal system for houses with limited space.

Is a combi boiler the right choice for me?

There are several benefits of having a combination boiler. Their compact size is a particularly attractive feature. By using a combi boiler you will not need a bulky tank or cylinder to feed your home heating and. Most systems also come with minimal piping, so if you need a new boiler installed it will be relatively straightforward.

Combi boilers also use water that feeds directly from the mains, meaning that hot water is always available on-demand and water pressure remains high even after extended periods of heavy use. 

In comparison to conventional boilers, combination boilers have some small disadvantages. For homes with more than one bathroom, a slight decline in water pressure may be experienced if more than one appliance is using the boiler at any one time.

To avoid this, try to minimise the strain on your boiler and avoid using several different appliances at the same time. Some combi boilers are better than others at adjusting water pressure and larger models will be better at combatting any decline in performance due to strain on the system.

Which combi boiler should I choose?

Combination boilers come in a range of sizes and style. Whether you’re looking for cheap boilers or a hoping to buy an eco-efficient model to help make savings on your bills, there will be a comination boiler to suit you and your home.

The first thing you need to consider is what size boiler you need. This will depend on the number of rooms and overall size of your home.
