When it comes to central heating servicing, homeowners often hear conflicting advice about how to make their boilers run more efficiently. From annual servicing schedules to modern smart controls, misinformation can lead to unnecessary expenses and reduced system performance. As trusted heating engineers at TSL Heating, we’re here to set the record straight.
In this guide, we’ll explore common boiler efficiency myths explained, why professional maintenance matters, and how regular boiler servicing and repairs can keep your home comfortable all year round.

Myth 1: “A New Boiler Always Means Better Efficiency”
Many homeowners assume that simply installing a brand-new boiler automatically guarantees improved efficiency. While modern condensing boilers are generally more energy-efficient than older models, their performance depends heavily on the system setup, correct sizing, and quality of installation. A poorly installed high-efficiency boiler can actually waste energy instead of saving it. Before replacing your system, consult a qualified engineer who can assess your heating needs and recommend the right boiler type for your property.
Myth 2: “You Only Need to Service Your Boiler When Something Goes Wrong”
This is one of the most expensive common boiler efficiency myths explained. Waiting for problems to occur before calling a heating specialist often leads to higher repair costs and energy wastage. Regular servicing keeps components clean, ensures safe operation, and identifies small issues before they become major breakdowns. Professional maintenance also helps preserve your manufacturer warranty.

Myth 3: “Turning the Heating On and Off Saves Energy”
Many people believe that frequently turning the heating off when they leave a room will lower energy bills. In reality, boilers work most efficiently when maintaining a consistent temperature. Constantly reheating the water in your system can increase fuel consumption and strain key components. Instead, use a smart thermostat or timer to balance comfort and energy use. This ensures your home stays warm without unnecessary fluctuations in energy demand.
Myth 4: “Older Boilers Can’t Be Efficient”
While it’s true that older boilers usually have lower efficiency ratings, proper maintenance can still make a significant difference. Cleaning heat exchangers, adjusting burner settings, and repairing minor leaks help even ageing systems perform more efficiently. Some homeowners in Cardiff find that after a thorough service, their older boiler’s performance improves enough to delay replacement costs. Regular servicing and repairs by a qualified engineer are key to ensuring optimal performance, regardless of the boiler’s age.
Myth 5: “Boiler Efficiency Doesn’t Affect the Entire Heating System”
Your boiler doesn’t work in isolation—it’s the heart of your central heating system. If it’s not running efficiently, other components like radiators and thermostatic valves also suffer. Balancing your system, bleeding radiators, and checking water pressure are all simple yet effective ways to ensure your heating works harmoniously. A well-maintained boiler reduces strain on the entire system, meaning fewer breakdowns and lower energy bills.
How to Ensure Your Boiler Runs at Peak Efficiency
Maintaining efficiency isn’t just about avoiding myths—it’s about adopting the right habits. Here are a few key practices every homeowner should follow:
- Schedule yearly servicing with qualified engineers.
- Check system pressure regularly and top up when needed.
- Bleed radiators to remove trapped air.
- Install a smart thermostat for better temperature control.
- Ensure your boiler is properly insulated and the flue is clear.
By combining professional care with regular home maintenance, you can save money, improve comfort, and reduce your carbon footprint.
