Post: Factors To Consider To Ensure The Boiler Is Energy Efficient

Factors To Consider To Ensure The Boiler Is Energy Efficient

All boilers need to be A-rated and have factory-certified efficiency of at least 92-94% (ErP). However, in practice, this object is never really reached.

Because the boiler is a small part of a much larger heating system. Hence, your entire heating system must work flawlessly and accurately as your boiler to achieve more than 90% efficiency.

As we discussed above, the unit must be fitted flawlessly. Subsequently, it would be best to have an expert installer do it into your existing network. Here are a few pointers you need to remember to achieve the best outcome.

The Unit Must Have A Small Minimum Output

Most of the boilers operate between 8-24kW or 3-30kW. It would help if you kept in mind that the lower the minimum out is of the range, the more efficient the boiler will operate all year. Hence, you need to check the output while installing it.

Choose The Size Correctly

Typically, even if it is a pretty cold day, a UK house requires a boiler range between 6-8kW. But, surprisingly, the houses contain many robust boilers and are bigger than needed.

So, for boiler installation, ask the installer to reduce the maximum output of the unit to match the needs.

You Need To Pair The Boiler Up With Compensation Controls

You need to get a compatible control system to install with your unit. Most advanced boilers vary in their outputs to meet the variable temperatures, which is undoubtedly pretty efficient.

However, the machine would only be able to do it if it is fitted with a control that allows it to speak the same language you do for easy understanding.

Find A Competent Installer!

Finding a competent installer is one of the most important steps for an efficient boiler. You need to research and find one superior to all of them. So, invest the required time to do research and find competent experts to do the job.

Here Is How You Can Calculate Potential Fuel Savings

If you have just purchased a new boiler and are confused about how much you would save on the bills, this section is for you. Here is all you need to know about calculations.

The average energy bill in the UK is around £750 – £1000. If the installer sets up the boiler correctly, your a-rated boiler will have an efficiency of 14-34%.

Your gas expenses won’t be significant or even reduced if you replace a boiler that is only a little over ten years old. There doesn’t seem to be much use in changing anything if it is dependable and inexpensive to maintain.

However, replacing badly constructed older boilers with significant maintenance expenses would likely be worthwhile.

On the other hand, an older boiler that you’ve had 20 years or more will be extremely an extremely inefficient boiler. Therefore, switching to a modern boiler will probably save upwards of £340 annually, but only if set up properly.

Here’s How You Can Calculate Your Savings On Your Energy Bill:
Say, for example, your annual heating bill is £800. You need to estimate the boiler’s current efficiency. It would be best if you made the estimate based on its shelf life. So, in this example, let us take it as 60%.
Now, calculate the efficiency of the new boiler you are thinking of installing. Let’s take it as 90%.
Subtract the current boiler’s efficiency from the new boiler; so, 90-60= 30%.
Multiply this with the annual heating bill. For example, 800 x 0.3 = £240 saving per annum

Important Considerations for Achieving Energy Efficiency in Boilers

To ensure that your boiler operates efficiently, there are several factors to take into account. While it’s ideal for all boilers to have an A-rating and a factory-certified efficiency of at least 92-94% (ErP), in reality, this target is seldom reached. This is because the boiler is just one component of a larger heating system, and to achieve over 90% efficiency, the entire system must function flawlessly and harmoniously with the boiler.

Proper installation is crucial, and it is recommended to have an expert installer integrate the boiler into your existing network. To achieve the best results, consider the following pointers:

Opt for a Boiler with a Low Minimum Output:

Boilers typically operate within a range of 8-244kW or 3-30kW. Keep in mind that a boiler with a lower minimum output tends to operate more efficiently throughout the year. During installation, ensure the output is checked and adjusted accordingly.

Choose the Correct Boiler Size:

Many homes in the UK have boilers that are larger than necessary. Despite this, a boiler range of 6-8kW is usually sufficient even on colder days. When installing a new boiler, request that the installer adjusts the maximum output to match your specific requirements.

Pair the Boiler with Compensation Controls:
To enhance efficiency, it’s important to install a compatible control system alongside your boiler. Advanced boilers can vary their outputs to adapt to varying temperatures, resulting in increased efficiency. However, this can only be achieved if the control system is compatible and allows for effective communication with the boiler.

Select a Competent Installer:

Finding a skilled and knowledgeable installer is crucial for ensuring an efficient boiler. Take the time to thoroughly research and locate professionals who are superior in their field. Investing in competent experts will yield better results in the long run.

Calculating Potential Fuel Savings:

If you’ve recently purchased a new boiler and want to estimate potential savings on your bills, follow these steps:

Determine the average energy bill in the UK, which ranges from £750 to £1000.

Assuming the installer has correctly set up your A-rated boiler, it will operate at an efficiency of 14-34%.

If your existing boiler is only slightly over ten years old and doesn’t require substantial maintenance expenses, the gas savings may not be significant. In such cases, it may not be worthwhile to replace it.

However, if you have an older boiler with frequent maintenance costs, replacing it with a more efficient model can result in substantial savings.

For boilers that are 20 years or older, upgrading to a modern boiler can potentially save over £340 annually, provided it is correctly installed.

Calculating Energy Bill Savings:

Let’s assume your annual heating bill is £800. Follow these steps to estimate potential savings:

Determine the current efficiency of your existing boiler based on its age. For example, if it’s 60%, use this figure for the calculation.

Estimate the efficiency of the new boiler you intend to install. Let’s assume it’s 90%.

Calculate the difference between the efficiencies of the current and new boilers (e.g., 90% – 60% = 30%).

Multiply this efficiency difference by your annual heating bill (e.g., £800 x 0.3 = £240 in savings per year).

By considering these factors and conducting the necessary calculations, you can ensure an energy-efficient boiler that optimizes cost savings.
