What is heating system inhibitor?

Maintaining your heating system is important for safety, longevity, and to save money. So should you use inhibitor chemicals?

Heating system inhibitor is a chemical additive that plays a crucial role in safeguarding and optimising the performance of a central heating system. It helps prevent corrosion, sludge build up, and limescale formation, maintaining the efficiency and longevity of the system

Do you have to use system inhibitor?

When added to the water circulating within the heating system, such as in radiators or underfloor heating, the inhibitor forms a protective layer on internal surfaces, including pipes and radiators. This layer acts as a barrier against rust and corrosion, enhancing heat transfer efficiency. Moreover, it effectively inhibits the growth of bacteria and algae, preventing blockages and unpleasant odours.

Heating system inhibitors typically contain a blend of chemicals like corrosion inhibitors, biocides, and scale inhibitors. These ingredients may include organic acids, phosphates, and silicates. Depending on the product, inhibitors can be in liquid concentrate form for direct addition to the system or in the form of tablets or cartridges placed in the radiator or boiler.

How often should you add inhibitor to your central heating system?

Regularly utilising a heating system inhibitor for your central heating system offers numerous benefits, such as prolonging its lifespan, optimising energy efficiency, and minimising the likelihood of breakdowns. It is crucial to adhere to the manufacturer’s instructions and recommended dosages to ensure the best possible performance and effectiveness of the heating system inhibitor.

Part of the service

When your boiler is serviced, your gas engineer will add inhibitor if needed. We only charge for the cost of inhibitor, and no additional labour charge. We don’t advise you to do it yourself as it can be very tricky for the non-professional to successfully dose the system.
