Boiler Efficiency Ratings Explained

Do you know what boiler efficiency ratings are and how they’re calculated? Boiler efficiency ratings are an important part of making sure your heating system is running safely, efficiently and cost-effectively.

Typically, heating and hot water account for over half of what you spend each year on energy bills, so an inefficient boiler will increase both your carbon footprint and your energy bills.

It’s important to understand the different levels of efficiency available as well as how they are calculated in order to make informed decisions when purchasing a new boiler or carrying out energy efficiency upgrades.

In our latest blog post, we explain the energy efficiency ratings of boilers and what they mean, as well as the government schemes in place to make boilers more efficient and how much money a new boiler could save you.

What Does Boiler Energy Efficiency Mean?

Boiler efficiency rating is measured by calculating the amount of energy that is used to heat water and keep your home warm in comparison to the amount that is lost or wasted. For example, a boiler that is 75% efficient means that 25% of the energy is lost.

In the UK, boiler efficiency is measured through an ErP rating, this measure replaced the old rating method known as SEDBUK (Seasonal Efficiency of Domestic Boilers in the UK) in 2015 though many manufacturers still provide the SEDBUK efficiency rating in their product information.

ErP stands for Energy Related Products and is a directive legislated by the European Union. Using ErP, boilers are given a rating on an A scale, ranging from A-G. The higher the letter grade, the more efficient the boiler is considered to be. Whilst higher ratings such as A++ are available, these can only be achieved using renewable technologies.

How Efficient Should My Boiler Be?

In 2018, the Government announced the Boiler Plus standards which state that the new minimum performance standard for domestic gas boilers in homes will be set at 92% ErP. However, this doesn’t apply to boilers in existing properties.

Ideally, your boiler should be A rated. As well as being more reliable and adding value to your home, the key benefit of a more efficient boiler is the lower running costs, this is because modern boilers are condensing and so recover more heat from the exhaust flue.

If you currently have the lowest rated boiler (G), upgrading to an A rated boiler can save you as much as £840 per year when used with programmable room thermostats and thermostatic radiator valves (TRVs); easily covering the cost of a new boiler in just a few years.

For more information, take a look at our blog post on how upgrading your boiler can save you £100s on your energy bills.

What Rating is My Boiler?

If you’re wondering how efficient your current boiler is, you should check for a sticker on the boiler which will show the efficiency rating. If you can’t find the sticker, we recommend searching online for the model and make of your unit where the efficiency rating should be available.

Without the sticker or model number, finding the rating on your own can be difficult. We recommend calling a gas safe registered engineer to come and check your boiler who will be able to find the make and model to determine how efficient the unit is.

If you find your boiler is not A-rated, we would highly recommend getting a quote on a new boiler to see how much you could save in the long term by upgrading. A boiler installation is typically not a messy job and can be completed in as little as 1 day if it’s just the unit being upgraded.

If you are living in a rental property, the landlord may be able to provide you with the boiler’s energy efficiency information from previous servicing. However, it’s important to note that as long as the boiler is working safely and being serviced, they do not have any legal obligation to upgrade your boiler but it may save them money over time on repairs.

Ensure Your Boiler Is Ready for Winter

As winter approaches and the temperature begins to drop, many homeowners across the UK will be considering switching their boilers back on, perhaps for the first time since last winter.

At a time when energy bills have increased significantly along with the overall cost of living, the last thing homeowners need is a problem with their boiler just as the colder months begin, potentially leaving them without heating and hot water.

Carrying out a few checks before winter can help ensure that your boiler works as expected, reduces the risk of an unexpected breakdown and ensures you have time to repair or replace the boiler if required.

Our latest blog post takes you through our recommended checks to carry out on your boiler before you begin to use it regularly again.

Recent Gas Combi Boiler Installation

All Our engineers are highly trained and Gas Safe Registered. The picture attached is from one of our recent Gas Combination (Combi) boiler replacements. As you can see the new Vaillant gas boiler looks more modern than the old one adding to the modern look of the kitchen.

Our client was very happy with work carried out and the improvement of hot water pressure the new Vaillant gas boiler has given them.

This job was completed in just one day and the system was Chemically Power Flushed. Our gas safe registered engineer removed the old boiler from the property along with all the packaging from the new gas boiler. Inhibitor was added to the system water to help prevent corrosion inside the pipework, boiler and radiators.

Additionally, new thermostatic radiator valves were installed to the radiators to help control the temperature in each room. A programmable room thermostat was installed in the hallway to help prevent the house from over heating. All controls were shown and demonstrated to our client so they know how it use them.

This boiler comes with a 7 year warranty that covers parts and labour.
