If, after bleeding the radiator, it still heats poorly, there may be more serious underlying causes. Sludge buildup is the most common. Over the years, the water in the heating circuit can generate oxides and mineral deposits that settle in radiators, particularly at the bottom. This sludge reduces the effective water flow area, creating cold spots. The solution is a chemical flush of the entire circuit using a specific descaling product, introduced with the boiler off and circulated for several hours. The system is then completely drained before refilling with new water treated with a corrosion inhibitor.

For apartments with a centralised community boiler, combining thermostatic radiator heads with individual consumption meters allows you to pay only for the heating you actually use, which is far fairer than the proportional distribution by surface area used when meters are absent. This is a mandatory upgrade in many communities due to European regulations. Deep cleaning of the heating circuit water with a specific descaler to remove sludge and oxides. Recommended every 7-10 years or when persistent cold spots occur. A blocked or faulty thermostat valve is another frequent cause. Modern valves with thermostatic heads have an internal pin that can seize up after months of disuse (common during summer in areas like the Costa Blanca when heating isn't used). To prevent this, it's advisable to move the thermostatic heads to their minimum and maximum settings every couple of months during the low season. If the valve is stuck, the head can be removed, the pin freed with a very gentle tap, or the entire valve replaced.

Aluminium radiators with low water content are the most efficient for most modern installations. They heat up and cool down quickly, allowing for precise hourly programming without sacrificing comfort. Panel steel radiators are a common alternative with good value for money.
