If, after bleeding the radiator, it still heats poorly, there could be more serious issues. Limescale and sludge buildup is the first common cause. Over the years, the water in the heating circuit generates oxides and mineral deposits that settle in the radiators, especially at the bottom. These deposits reduce the water flow area, creating cold spots. The solution is a chemical flush of the entire circuit with a specific descaling product. This is introduced with the boiler off and circulated for a few hours. The system is completely drained before refilling with new water treated with a corrosion inhibitor.

For apartments with a central community boiler, combining thermostatic radiator heads with 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 improvement in many communities due to European regulations. A deep clean 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. The second frequent cause is a blocked or faulty thermostat valve. Modern valves with thermostatic heads have an internal pin that can seize after months of disuse (which happens every summer on the Costa Blanca when the heating is not used). To prevent this, it's advisable to move the thermostatic heads to the maximum and minimum settings every couple of months during the low season. If the valve is stuck, the head is removed, the pin is freed with a very gentle tap, or we replace the entire valve.

Low-water content aluminium radiators are the most efficient for most modern installations. They heat up quickly, cool down quickly, and allow fine-tuning of hourly programming without sacrificing comfort. Panel tubular 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.
