According to close to 15% of the carbon emissions in the UK coming from the way we heat our homes, ensuring your boiler is energy efficient will help fight the climate crisis. Plus, it will help you save money on energy bills!

Here’s how you can improve your boiler’s efficiency:

1. Annual Boiler Service

If you want your boiler to run effectively and efficiently for as long as possible, it’s critical to have it serviced at least once a year. It’s similar to how cars need annual MOT tests to ensure safety, roadworthiness, and emissions.

Ensure you schedule for your boiler to be serviced by a registered Gas Safe engineer annually. It will involve testing and checking your gas boiler to ensure it runs smoothly and safely.

It will also help you identify preventable issues that can turn into expensive and potentially dangerous problems when left unchecked. If you’re using an oil boiler, an OFTEC technician is suitable for the annual boiler service.

2. Buy a New High-Efficiency Boiler

When you’ve tried all the above and nothing seems to improve the efficiency of your boiler, it’s time to get a new one. If you struggle to heat your water or home efficiently or you installed your boiler over eight years ago, you may have to consider a replacement.

All boilers have to be replaced at some point eventually, and the modern ones are highly efficient. Ensure you get an A-rated condensing boiler. It’s currently the most efficient one in the market, and it can reduce your heating costs by up to £305 every year.

New modern combi boilers are also more reliable and economical to use. Efficiency and peace of mind are guaranteed once you invest in one, and it’s installed correctly.

3. Regularly Clean Boiler

Over time, dust will settle on your boiler’s exterior, and it can get into the pipes and tubes and clog them up. This will hamper the performance of your boiler and result in increased energy bills!

A simple solution is to clean the outer section of your boiler as you clean your house, preventing dust from settling and accumulating. You should never try to clean your boiler’s interior unless you’re a licensed expert. The Gas Sage registered engineer can take care of that during servicing.


4. Radiator Bleeding

Occasionally bleeding your radiators ensures they run effectively and improves their heat efficiency. It’s a minor task that will have you reaping big on energy cost savings.

Air gradually enters your boiler’s heating system, resulting in blockages that make the top half of your radiator cooler than the bottom. If any of your radiators take a while to warm up after you fire up the heating or there are cold spots at the top, then they need bleeding.

Radiator bleeding ensures any trapped air has a way out of the heating system, so hot water circulates the radiator. It’s a simple solution that will give you peace of mind and ensure your radiator isn’t overworked.

5. Keep Water Pressure Topped Up

Insufficient water pressure translates to an inefficient boiler. Once the pressure drops, your boiler must work harder and use more fuel and energy to heat your home.

Always check the pressure of your boiler on the pressure gauge. The pressure can slowly decrease over time, or it can drop suddenly because of a water leak or after you’ve bled your radiators.

Fortunately, you can correct this and increase the boiler pressure yourself through a step-by-step guide or hire a professional. Typically, it should be between 1 and 2 bars, but you should check the manufacturer’s instructions in the boiler manual.

6. Pipe and Cylinder Insulation

Insulation is a key priority if you want to reduce heating bills and keep your house warmer. Many DIY stores offer insulation, but most people often overlook insulating their pipes and cylinders.

If you’re using a regular or system boiler, then you have a cylinder. Ensure you wrap it with insulation and use simple foam tubes to lag your central heating pipes.

It will reduce heat loss and keep hot water warmer for longer. It will help you reduce energy usage and save you heating bills because your boiler won’t have to heat water often.

7. Switch Your Heating on Monthly

You may be tempted to turn your boiler off during the summer, but this is a bad idea. Although it will help you save money on energy and heating bills, it can be detrimental to your boiler.

It can seize up when you leave it off for long and develop faults or breakdowns further down the line. Ensure you run your boiler at least once monthly, even in the warmer months.

It will help ensure it’s in tip-top shape, prevent the pipes from seizing up and keep the heating system effective and efficient.

8. Power-Flush Your System

Over time, sludge deposits can collect in your radiators and pipes and compromise the efficiency of your boiler. Components of your heating system may also get corroded gradually.

If you notice some components aren’t working, cold spots, or it takes a long time to heat, it might be time to flush your system. Powerflushing units can send water through your heating system at high speeds and dislodge any rust, sludge, or debris build-ups.

An engineer registered by Gas Safe can help you do this. It will increase the durability and efficiency of your central heating and boiler.

9. Install a Small Thermostat

More control can easily translate to higher efficiency. As smart thermostat enables you to monitor and control your heating system anywhere, anytime. Some of the best intelligent thermostats include features like:

·     Heating monitoring and control from a tablet or smartphone from wherever you are.

·     Tracking weather changes and adjusting the heating automatically.

·     Adaptation of the boiler to your unique heating habits.

·     Geolocation technology informs it when the home is empty and enables it to keep the heating off. You’ll never have to worry about leaving the heating on ever again.

Final Thoughts

Use these top tips to improve your boiler’s efficiency and watch your energy bills decrease while feeling a sense of doing your bit for the environment.
