Boilers
Which type of boiler is best for me?
Gas and oil boilers are either ‘system’ boilers, which have a separate hot water cylinder to store hot water, or ‘combi’ boilers, which heat hot water on demand and don’t require a hot water cylinder.
A system boiler is more efficient than a combi boiler at producing hot water, however heat is lost from the hot water cylinder over time.
A combi boiler could be more efficient overall, although this depends on several factors such as how many people there are in the property and whether you are likely to install solar panels in the future.
Having a hot water cylinder allows you to store energy from a solar system – if you are not able to install solar panels then this might influence your decision.
Choosing the right boiler for you will depend on different things, including:
- Size of property
- How many people stay in the house
- How many bathrooms
- How many radiators
Why choose an A-Rated Boiler
An A-rated boiler is considered top of the range with an efficiency rating of at least 90 percent.
The Energy Saving Trust recommends all A-rated boilers as the best choice for UK customers.
Whether you need a new boiler to your current one that is constantly breaking down or trying to increase the value of your home, an A-rated boiler should be a top priority.
Choosing an A-rated boiler is the best choice as you’ll save money and minimize the impact on the environment simultaneously.
