If the radiator continues to heat poorly after bleeding, there are other, more serious potential causes. Sludge build-up is the first. Over the years, the water in the heating circuit generates oxides and mineral deposits that settle in the radiators, particularly 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.

For apartments with a centralised community boiler, the combination of thermostatic heads and individual consumption meters allows you to pay precisely for the heating consumed by each dwelling, which is much fairer than the proportional distribution by surface area used when there are no meters. This is a mandatory upgrade in many communities due to European regulations. A very cost-effective upgrade is to install thermostatic heads on each radiator. Each room will have its own independent temperature control, allowing different temperatures according to use (warmer in the living room when occupied, cooler in the unused guest room) and saving energy without losing comfort. Installation is straightforward when radiators already have conventional valves: we replace the manual head with a thermostatic one. 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.

Low-water-content aluminium radiators are the most efficient for most modern installations. They heat up quickly, cool down quickly, and allow for precise hourly programming without compromising comfort. Tubular panel steel radiators are a common alternative with good value for money. For bathrooms, we recommend towel rail radiators that combine room heating with towel drying. Boilers\\ \\ Installation and repair of gas and electric boilers.
