How to choose the right boiler

Choosing the right boiler for your home can be an overwhelming decision. A new boiler can last around 10-15 years, so it’s important to find the right one to suit you and your lifestyle. Before purchasing a new boiler, it’s important to think of factors such as your heating and hot water requirements and any future home improvements you may be considering. The information below is designed to make choosing the right boiler for your home that little bit easier.

Boiler Types

At Worcester Bosch, there are three types of boiler that we manufacture; Combination (Combi) boilers, System boilers and Regular boilers. All three types vary and are suited for different homes and living situations. Combis boiler are small and compact and provide instant hot water, whereas System boilers require a hot water cylinder for storing hot water. Regular boilers require a cold water tank as well and are usually found in homes with a traditional heating system. 

If your looking for more information on boiler types, our boilers explained page will be able to help.

Fuel Types

Combi, system and regular boilers are available in gas, LPG (liquefied petroleum gas) and oil variants. Gas boilers tend to cost less to operate than oil-fired boilers, however the fuel type you choose will depend on what’s available in your area. The type of fuel used to power your system can be more effective with certain types of boilers, we recommend contacting your local Worcester Accredited Installer for professional advice.

Boiler Sizes

The size of a boiler is measured in kilowatts rather than the actual physical dimensions. Kilowatts are a measure of the power output from the boiler. Generally speaking, the larger the kilowatt output the more demanding your heating and hot water requirements tend to be. Worcester Bosch provide boilers for the entire spectrum, ranging from 9 kilowatts to 50 kilowatts.

When choosing the right boiler for you, begin by considering your heating and hot water needs, as different types of boilers are able to fulfil each homes necessary requirements. For example a combi-boiler provides heating and hot water on demand from the mains water supply, however if you have a large family or your home has more than one bathroom, a combi may struggle to provide the necessary amount. If you tend to use a large amount of hot water, a regular or system boiler may be a better match.  The information below shows the main boiler types, how they work and what kind of homes they work best in.

You should chose the boiler with the correct output for your home, there is no need or benefit of choosing a higher output than you need. To help find a boiler with the right output for your home, use our find a new boiler tool.
