If, after bleeding the radiator, it's still not heating properly, there could be more serious underlying causes. Sludge build-up is often the first culprit. Over the years, the water in the heating circuit accumulates rust and mineral deposits that settle in the radiators, particularly at the bottom. This sludge narrows the water channels, creating cold spots. The solution is a chemical flush of the entire circuit using a specific descaling product, circulated when the boiler is off for a few hours. It’s completely drained before refilling with new water treated with a corrosion inhibitor.

For apartments with a centralized community boiler, combining thermostatic radiator valves (TRVs) with individual consumption meters allows you to pay only for the heating used by your flat, which is fairer than proportional billing based on surface area when meters aren't installed. This is a mandatory upgrade in many communities due to European regulations. A highly cost-effective upgrade is installing TRVs on each radiator. Each room gets its own independent temperature control, allowing for different temperatures depending on usage (e.g., warmer the living room when occupied, cooler the 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. The second common cause is a blocked or faulty thermostat valve. Modern valves with thermostatic heads have an internal pin that can seize after months of disuse (as happens every summer on the Costa Blanca when heating isn't used). To prevent this, it's advisable to move the TRV heads to their maximum and minimum settings every couple of months during the off-season. If the valve is stuck, we remove the head and free the pin with a gentle tap, or replace the entire valve.

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 compromising comfort. Tubular panel steel radiators are a common alternative with a good price-quality ratio. For bathrooms, we recommend towel rail radiators that combine room heating with towel drying. Official manufacturer warranty (5-7 years depending on brand, e.g., Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day cover on labour and recommended annual inspections. Official manufacturer warranty (5-7 years) plus our labour coverage.

The price for annual maintenance in Provençals del Poblenou typically ranges between €160 and €4165. The final figure depends on the property's condition, materials, and time required. We always provide a fixed quote before starting. A complete aerothermal system installation is a significant project. It begins with calculating the home's thermal loads, sizing the equipment according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the domestic hot water tank and outdoor unit, and providing a fixed quote.
