Advantages

Regular maintenance pays off.

Millions of heating systems across homes are operating below their optimal efficiency. One of the primary reasons? Insufficient maintenance. With today's high fuel costs, professional maintenance quickly pays for itself – especially considering that a modern heating system requires minimal upkeep despite its workload. Your boiler's annual operating hours equate to approximately 100,000 kilometers of car travel, making regular attention essential for efficient performance. Even small issues can significantly impact your energy consumption – each millimeter of soot or dirt on heat exchanger surfaces increases fuel consumption by 5%. Simply by having your space heating professionally cleaned, you'll experience immediate cost savings while extending your system's lifespan.

Optimise your heating performance

These quick tips will help you heat your home more efficiently.

Night setback.
Check your central control system's night reduction settings and adjust them for optimal efficiency.
Radiator cleaning.
Clean your radiator fins regularly – dust reduces heat transfer efficiency and extends warming times.
Correctly place furniture.
Ensure radiators aren't blocked by furniture, especially after summer, when you may have rearranged your rooms.
Water pressure.
Verify your system's water pressure and top up if necessary to maintain recommended levels.
Radiator check.
Inspect all radiators for leaks and bleed them to release trapped air for improved performance.
Learn how to bleed your radiators
Thermostats.
Examine thermostat valves to ensure they move freely and replace any that are sticking or malfunctioning.

Your heating system in perfect balance

Optimise your heating settings: with hydraulic balancing.

Hydraulic balancing is carried out by a qualified expert. Afterwards each radiator receives precisely the energy it needs – no more, no less. This calibration eliminates wasteful hot and cold spots throughout your home while reducing both electricity and heating costs. You can find out more about hydraulic balancing in our guide.

Frequently asked questions

Still have questions? We have the answers.

How much can I really save through regular heating system maintenance?

Regular professional maintenance can reduce your heating costs by 10-15% annually. When your system operates at peak efficiency, it converts fuel to heat more effectively, requiring less energy to maintain your desired comfort level. Consider that just 1mm of soot on heat exchanger surfaces increases fuel consumption by 5% – a thorough cleaning alone delivers immediate savings. Beyond reduced energy bills, proper maintenance extends your system's lifespan and helps avoid costly emergency repairs. For a modern home, this typically translates to several hundred euros saved each year while ensuring reliable, efficient heating performance.

Is a hydraulic balance worth the investment for my heating system?

Absolutely. Hydraulic balancing is one of the most cost-effective improvements you can make to an existing heating system. This professional calibration ensures each radiator receives precisely the right amount of hot water, eliminating wasteful hot and cold spots throughout your home. After this one-time adjustment, you can expect energy savings of 5-15% annually, with the service typically paying for itself within the first heating season. Beyond the financial benefits, you'll enjoy more consistent comfort throughout your home and reduced system noise, while extending the operational life of your heating components.

How do I know if it's time to replace my heating system rather than maintain it?

Consider replacement when your current system is over 15 years old, requires frequent repairs, or operates at less than 80% efficiency. Modern heating systems achieve efficiency ratings of 95% or higher, potentially reducing your energy consumption by 20-30% compared to older models. Calculate your potential savings by comparing your current annual heating costs against the expected reduction with a new system – if the difference would offset the installation cost within 5-7 years, replacement is often the more economical choice. Additionally, new systems offer enhanced comfort features, smart controls, and significantly reduced environmental impact, future-proofing your home's heating infrastructure.
