The efficiency of your boiler is of utmost importance if you want to avoid paying more than you should to heat your home. The technology behind boilers has advanced to such a level that modern systems are often deemed as more efficient and less likely to raise your energy bills**. We aim to help you save by providing you with the advice you need to enhance your control over your central heating system.

Energy-efficiency ratings range from A to G, with A being the most efficient. We work with top brands like Worcester Bosch and Ideal to ensure that the boilers we install are A-rated for maximum efficiency.

How to increase efficiency of the boiler


1. Upgrading your boiler could save you money

According to The Energy Saving Trust, a new energy-efficient boiler with a full set of heating controls could save you around £200 a year in heating costs**.

The older a boiler gets, the more expensive it could be to repair as old parts may fall out of production and get more difficult to replace. This means that it could make financial sense to invest in a new boiler, as the prospect of an old boiler failing in the middle of winter is nobody’s idea of fun.

New boilers are designed to be much more reliable and if they happen to malfunction, replacement parts tend to be much easier to get hold of.


2. Controlling the temperature could slash your bills

Turning down your thermostat by as little as one degree could reduce your heating bills by almost 10%(Energy UK). It might not sound like much, but a slight tweak could really make a difference if you use your central heating on a regular basis; we recommend setting your temperature at the lowest comfortable level.

Smart thermostat technology is designed to do exactly this for you; it could make your heating more efficient by working out the best schedule for your home based on when you’re in and which rooms you use most often. After learning your heating routine, the smart thermostat tells your boiler when to heat up, which could prevent you from wasting energy and potentially help lower your energy bills**.


3. Ensuring the right pressure is set could increase efficiency

Your boiler pressure gauge should measure between 1 and 1.5. If the pressure is too low, you could receive high energy bills due to inefficiency. If it is too high, your boiler will be under unnecessary pressure and could be more likely to develop faults. If you see that the dial on your boiler is indicating an unusual reading, you could reduce the pressure by repressurising your boiler.


4. Upgrading other elements of your home could help

Even if your boiler is working at its most efficient level, you may be losing heat through the likes of old windows and poorly insulated walls, so be sure to consider all elements of your household when seeking to enhance your home’s overall efficiency.


5. Inefficiency costs more in the long run

Around 70% of what you spend on energy bills annually can be attributed to the efficiency of your boiler, so it’s important to invest in the most efficient unit within your budget (Energy UK) . Remember, cheaper isn’t always better. Purchasing the cheapest option may cause you to ultimately spend more as you may have to fork out for frequent repairs.
