When choosing a new boiler consider factors such as boiler efficiency, space savings, hot water production, gas and water bills, and more

Boiler efficiency ratings don't give you the complete picture when it comes to boiler efficiency as they don't include all the factors that contribute to gas use.

You may or may not be interested in greener performance; you are almost certainly interested in saving money on your gas and water bills. You'll find efficiency ratings for boiler manufacturers at the Home Heating Guide website.

However, even 'A' rated boilers do not give you maximum boiler efficiency as they lose energy via the flue, noticeable as 'pluming', that resembles steam.

It could be that GasSaver would be a good investment for you, depending on your daily or seasonal energy needs. GasSaver enables households to capture wasted heat and use it for hot water production.

GasSaver has been shown in independent tests to reduce the energy required for hot water production by 37%. You'll also save up to 7% on your water bill and enjoy hot water running faster to your taps.

When it comes to boilers, there are many good brands available. Modern condensing boilers are generally efficient, quiet and reliable, and most receive good customer reviews.

When you select a replacement boiler, consider: replacement boiler checklist

Here are some things to consider when deciding what type of replacement boiler is right for you.

Fuel type

Most UK households have a gas heating system equipped with a gas boiler. For those households not connected to the main gas network, options include oil boilers, liquid petroleum gas or LPG boiler, or a stove fitted with a back boiler. 

Boiler type

You could replace your boiler with a combination (or combi) boiler, which provides heat for radiators and domestic hot water, or a heat-only boiler, which is connected to a hot water storage system.

Boiler efficiency 

The Energy Saving Trust suggests central heating gas boilers account for 60% of a home's CO2 emissions. So, your boiler choice is a priority if you want to reduce your fuel bills and carbon footprint.

Boiler installation 

Boiler installation must be carried out by a professional heating engineer on the Gas Safe Register.

Do some background checks on boilers, boiler efficiency and customer reviews before selecting an installer.

Some installation companies, including services offered through British Gas and other energy companies, may suggest a replacement boiler for you. Make it clear to the installer at the beginning if you have a preferred model in mind.
