If the radiator continues to heat poorly after bleeding, there may be more serious underlying causes. Sludge build-up is the most common. 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 water flow path 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 is then fully drained before refilling with new water treated with a corrosion inhibitor.

A highly cost-effective upgrade is installing thermostatic radiator valves (TRVs) 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 losing comfort. Installation is straightforward when radiators already have conventional valves: we replace the manual valve 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. The second common cause is a blocked or faulty thermostat valve. Modern valves with thermostatic heads have an internal pin that can seize up after months of disuse (which happens every summer in the Costa Blanca area when the heating is not used). To prevent this, it is advisable to move the thermostatic valve heads to the maximum and minimum settings every couple of months during the low season. If the valve is blocked, 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 and cool down quickly and allow for precise hourly programming without compromising comfort. Panel-type 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.
