If the radiator is still heating poorly after bleeding, there are other, more serious potential causes. Sludge buildup is the primary one. Over the years, the water in the heating circuit generates oxides and mineral deposits that settle in the radiators, especially at the bottom. This sludge reduces the effective water flow area and creates cold spots. The solution is a chemical flush of the entire circuit with a specific descaling product, introduced with the boiler off and circulated for a few hours. It's completely drained before refilling with new water treated with a corrosion inhibitor. Select the service you need for more details and to request a quote.

Deep cleaning of the heating circuit water with a specific descaler to remove sludge and oxides. This should be done every 7-10 years or when persistent cold spots occur. A very cost-effective improvement is installing thermostatic heads on each radiator. Each room has its own independent temperature control, allowing different temperatures according to use (warmer in the living room when occupied, cooler in an unused guest room) and saving energy without sacrificing comfort. Installation is straightforward when radiators already have standard valves: we replace the manual head with a thermostatic one. For apartments with a central community boiler, combining thermostatic heads with individual consumption meters allows you to pay only for the heating consumed by each dwelling, which is much fairer than proportional distribution by surface area used when there are no meters. This is a mandatory improvement in many communities due to European regulations.

Low-water-content aluminium radiators are the most efficient for most modern installations. They heat up quickly, cool down quickly, and allow for fine-tuned programming without compromising comfort. Panel tube steel radiators are a common alternative offering good value for money. For bathrooms, we recommend towel rail radiators that combine room heating with towel drying.
