How much can a new A-rated boiler reduce your heating bills this Winter?

Upgrading your boiler can be a big decision, but it can also be a great way to save money, lower your carbon footprint and increase your home’s overall comfort. If you didn’t know already, newer boilers are much more efficient than older models, meaning they have a lower energy usage and cost less to operate. 

New efficient boilers are more reliable, with advanced features that make them easier to maintain and control. In addition, more recent, more modern boilers often come with more extended warranties, giving you peace of mind if something goes wrong.

If you have an inefficient boiler over 15-20 years old, it’s worth considering upgrading to a modern one. You’ll enjoy greater boiler efficiency, reliability, and comfort – In this blog, we will go over what a new a-rated boiler can do for you and your heating bills.

The Type of Boilers

As crucial as a rated boiler is, the type of boiler is just as important, as each one benefits a specific household more than others. There are four boilers to choose from in the boiler world: Combi, System, Regular and Electric. Each one has benefits better suited for some households than others, so picking the right one is essential. 

Combi Boilers

A combi boiler, also known as a combination boiler, is a highly efficient boiler that provides heat and hot water on demand. With a combi boiler, there is no need for a separate water heater, as the boiler itself heats the water as needed. Combi boilers are compact and efficient, making them perfect for smaller homes.

System Boilers

A System boiler heats water in a sealed system, eliminating the need for a separate hot water cylinder. With a system boiler, you can also store hot water in a tank, so you don’t have to wait to heat up whenever you want to use it. We believe system boilers are excellent for larger homes with multiple bathrooms, so keep that in mind.

Regular Boilers

A regular boiler is a type of domestic heating system which provides central heating and hot water using a storage tank. A regular boiler is an ideal choice for many homes, especially those with more than one bathroom, as it provides a reliable source of hot water without needing a high-pressure system.

Electric Boilers

An electric boiler uses electricity rather than gas to heat water; this means that it is 100% efficient – all the heat created is used to heat the water, so there are no unpleasant fumes or emissions. Electric boilers are also very quiet and can be used in any room in the house, as they don’t produce exhaust gases.

A-G Rated Boilers

If you’re shopping for a new boiler, you may have noticed that every boiler has an energy efficiency rating. These ratings range from A (the most energy efficient) to G (the least efficient). So what does it mean to have an A-rated boiler compared to a G-rated one?

The efficiency ratings are as follows:

  • A – 90% and above
  • B – 86-90%
  • C – 82-86%
  • D – 78-82%
  • E – 74-78%
  • F – 70-74%
  • G – below 70%

A and G-rated boilers are assigned an efficiency score between 0 and 100. This score reflects the percentage of the heat generated by the boiler used to heat your home. The remaining percentage is what is potentially lost and is losing you money.

The most significant difference is in efficiency. An A-rated boiler will use much less fuel than a G-rated model, making it cheaper to operate in the long run. Higher-rated boilers can quickly add to significant savings, especially if you have a large home or run your boiler for extended periods. In addition, A-rated boilers tend to have lower emissions than their less efficient counterparts, making them better for the environment.


To conclude, picking the correct boiler is an important decision that could save you money on your annual energy bills. With so many models on the market, it’s not easy to know which one is right for your home. However, by taking the time to read this blog, research, and pick a high-quality boiler, you can enjoy lower energy bills and more comfortable home.
