Does the energy efficiency of boilers matter?

Key takeaways:

  • The higher the boiler’s efficiency, the less fuel it will use to achieve the desired output.
  • An energy-efficient boiler has a rating of 94%, meaning that only 6% of its energy is wasted.
  • Boiler efficiency is measured by ErP Class and SEDBUK.

As the cost of energy bills in the UK continues to soar, many households are looking for the secret to lowering their heating bills.

The answer is boiler efficiency.

Boilers account for around 60% of what you spend in a year on energy bills, so an inefficient boiler could be costing you a lot of money.

Luckily, a new energy-efficient boiler could save you up to 30% a year on your energy bills.

That’s why it’s worth asking, is it worth upgrading to an energy-efficient boiler?

In this blog post, we’ll explore how the energy efficiency of boilers is rated, why boiler efficiency is important and how you could get a new boiler for free.

Why is boiler efficiency important?

Boiler efficiency is vital to keeping your energy bills low.

By measuring how well a boiler uses fuel to heat water or produce steam, households can make significant savings over time all while reducing their emissions of greenhouse gases and other pollutants.

This is because an efficient boiler will use less fuel to achieve the desired temperature.

For example, an energy efficient boiler with a 94% efficiency rating will only waste 6% of its fuel, while an older boiler may be operating at an efficiency level of 60%.

However, in the UK, boilers are required by law to have a minimum energy efficiency rating of 86%.

This means that for every £100 of fuel used by the boiler, at least £86 worth of heat is generated.

What affects energy efficiency in boilers?

Many factors affect boiler efficiency, including the type of boiler, its size and age, the quality of its insulation, and the temperature of the water it is using.

In almost every case, newer, higher-efficiency boilers can often achieve significant savings compared to older models.

When considering whether to upgrade to a more energy-efficient boiler, it’s important to weigh the initial cost of the boiler against the potential savings in fuel and operating costs over time.

In many cases, an energy-efficient boiler will pay for itself in just a few years through lower energy bills.

How is the energy efficiency of boilers rated?

The energy efficiency of a boiler is measured in two ways:

1) Seasonal Efficiency of a Domestic Boiler in the UK (SEDBUK)

The SEDBUK rating is a measure of how efficient the boiler is when used over an entire heating season.

This rating is expressed as a percentage and is calculated by taking into account the boiler’s fuel consumption, operating efficiency, and standby loss.

2) ErP class

The ErP class is a measure of how energy efficient the boiler is when compared to other models on the market.

This rating is expressed as a letter, with A being the most efficient and G being the least efficient.

A high ErP is important when shopping for a new boiler, as it will determine how much you can save on your energy bills.

For example, if you buy a boiler that is in the A class, you could save up to 30% on your energy bills compared to a G-rated boiler.

My boiler works just fine, why do I need an upgrade?

Even if your boiler is working fine, there are still many reasons to consider upgrading to a more energy-efficient model.

Over time boiler efficiency declines, meaning that upgrading can lead to significant savings on your energy bills. In addition, newer boilers are also much cleaner and produce fewer emissions of harmful pollutants.

Will a new boiler save me money?

Yes, a new boiler will save you money.

A new boiler is more energy-efficient than an older model, which means that it will use less fuel to heat your home. This will lead to lower energy bills and can help you to save money over time.

How much does a boiler replacement cost?

The cost of a boiler replacement will vary depending on the type and size of boiler you choose.

However, you may be able to get a new boiler for free through the government’s Energy Company Obligation (ECO) scheme.

Under this scheme, energy companies are required to provide free or discounted boilers to low-income households.

What is the free Boiler Upgrade Scheme?

Depending on your circumstance, you could get your boiler replacement for free.

The Boiler Upgrade Scheme is a government initiative that offers free or discounted energy efficient boilers to low-income households.

Available until 2025, the Boiler Upgrade Scheme allows property owners to receive grants encouraging them to install low-carbon heating systems in their homes, like heat pumps.

Under the upgrade boiler scheme, energy companies are required to provide free or discounted boilers to low-income households.

To qualify for this boiler replacement government scheme, you must be receiving certain benefits, such as Pension Credit, Jobseeker’s Allowance, or Universal Credit.
