Understanding Boiler Efficiency
Boiler efficiency can be measured by calculating the Seasonal Efficiency of a Domestic Boiler in the UK (SEDBUK) rating, which is a percentage. A higher SEDBUK percentage indicates better efficiency. Since April 2018, all UK-installed boilers must have an EPR rating of 92% or higher.
Another way to assess boiler efficiency is by its ERP (energy-related product) rating. This grading system ranges from A (best) to G (worst). Most modern boilers have an A rating, while older boilers typically fall within the D-G range.
Types of High-Efficiency Boilers
Condensing Boilers
Condensing boilers are the most efficient type of boiler. They are designed to extract more heat from the fuel they burn by using the heat from exhaust gases that would typically be wasted. Condensing boilers can reach efficiencies of over 90%.
Electric Boilers
Electric boilers provide an eco-friendly alternative to gas boilers. These boilers are 100% efficient, converting electricity directly into heat. Although they may have higher running costs, they produce no harmful emissions and require less maintenance.
System Boilers
System boilers store hot water in a cylinder, making them more efficient than traditional boilers. They can provide hot water to multiple taps at once without a loss in pressure. This type of boiler is ideal for larger homes and families.
Biomass Boilers
Biomass boilers use renewable energy sources, such as wood pellets or chips, to generate heat. They can be highly efficient, especially when using high-quality fuel. Biomass boilers also help to reduce your carbon footprint.

Enhancing Boiler Efficiency
Insulate Boiler Pipes
Adding foam insulation to your boiler’s central heating pipes helps retain heat and reduces the workload on your boiler, saving you money.
Regular Servicing
Schedule annual service checks with a professional to identify potential issues and maintain your boiler’s efficiency.
Keep Your Boiler Clean
Regularly clean your boiler and ensure proper ventilation to prevent debris buildup and maintain efficiency.
Monitor Boiler Pressure
Monitor your boiler’s pressure to ensure optimal performance. Adjust pressure as needed and consult a professional if you’re unsure about the process.
Bleed Radiators
Bleed your radiators to release trapped air and improve heat distribution. This will help your boiler work more efficiently.
Use a Powerflush
A powerflush clears sludge and debris from your pipes and radiators, preventing corrosion and improving your boiler’s efficiency. Hire a Gas Safe Engineer to perform the powerflush.
Run Your Heating Periodically
Running your heating system for short periods during warmer months helps maintain your boiler’s efficiency and prevents it from seizing up.
Conclusion: Making the Right Choice
Selecting the most efficient boiler for your home can save you money on energy bills and reduce your carbon footprint. By comparing different types, models, and brands, you can make an informed decision that best suits your needs.
Investing in a high-efficiency boiler, combined with proper maintenance and care, can provide you with long-lasting warmth, comfort, and savings. Get started by comparing quotes from professional installers to find the perfect boiler for your home.
