However, to ensure optimal performance and longevity, it’s important to take certain steps to maintain and improve your combi boiler. In this article, we’ll share eight combi boiler secrets that can help you improve efficiency, reduce energy bills, make maintenance easier, and prolong the lifespan of your combi boiler.

Install a Programmable Thermostat 

One of the easiest ways to improve the efficiency of your new combi boiler is to install a programmable thermostat. This allows you to set the temperature to automatically adjust throughout the day, reducing energy consumption and lowering your energy bills. With a programmable thermostat, you can set different temperatures for different times of the day, so you’re only heating your home when you need it.

Insulate Your Pipes

Insulating your pipes is a simple and inexpensive solution that can make a big difference in your energy bills and your boiler’s performance. By insulating your pipes, you can reduce heat loss, improve the efficiency of your combi boiler, and help to extend its lifespan. Insulated pipes also help to prevent frozen pipes during the winter months.

Perform Regular Maintenance

Regular maintenance is key to keeping your combi boiler running efficiently and extending its lifespan. This includes things like cleaning the boiler and checking for leaks, as well as annual servicing by a professional. Regular maintenance can help to identify and fix problems early, preventing more costly repairs down the line.

Use a Power Flush

A power flush is a cleaning process that removes sludge and debris from your heating system. By using a power flush, you can improve the efficiency of your combi boiler, reduce energy bills, and prolong the lifespan of the system. A power flush is especially important if you’ve noticed any problems with your heating, such as cold spots or poor water flow.

Install Thermostatic Radiator Valves (TRVs)

TRVs allow you to control the temperature of individual rooms, reducing energy consumption and improving efficiency. By installing TRVs, you can also extend the lifespan of your combi boiler by reducing strain on the system. TRVs are a cost-effective solution that can help to improve the comfort of your home while also saving you money on your energy bills.

Consider Upgrading to a High-Efficiency Combi Boiler

If your current combi boiler is outdated or inefficient, upgrading to a high-efficiency model can help to reduce your energy bills and improve performance. Look for models with a high AFUE (Annual Fuel Utilization Efficiency) rating. A high-efficiency combi boiler can pay for itself over time through lower energy bills and improved reliability.

Use a Water Softener

If you live in an area with hard water, using a water softener can help to prevent scale buildup in your combi boiler. Scale buildup can reduce efficiency and shorten the lifespan of your boiler. A water softener works by removing minerals from your water, so it’s important to choose the right size and type for your home.

Consider Using a Magnetic Filter

A magnetic filter can help to remove sludge and debris from your heating system, improving the efficiency of your combi boiler and prolonging its lifespan. This is an effective way to prevent future problems and reduce the likelihood of costly repairs. The filter works by attracting and trapping magnetic particles that can build up in your system over time.


By following these eight combi boiler secrets, you can improve the efficiency of your heating system, reduce your energy bills, and extend the lifespan of your combi boiler. Simple steps like installing a programmable thermostat, insulating your pipes, and performing regular maintenance can go a long way in ensuring optimal performance and reliability. Plus you should always ensure your combi boiler installer is certified, use Gas Safe Register to check if they are a legit compliant gas combi boiler installer. 

Upgrading to a high-efficiency combi boiler, using a water softener, and considering a magnetic filter can also help to further improve efficiency and prolong the lifespan of your system. By taking care of your combi boiler, you can enjoy reliable heating and hot water for years to come.
