If the radiator still heats poorly after bleeding, there could be more serious causes. Sludge build-up is the most common. Over the years, the water in the heating circuit accumulates rust and mineral deposits that settle in the radiators, especially at the bottom. This sludge reduces the 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. It's completely drained before refilling with new, treated water containing corrosion inhibitor.

For apartments with a centralised community boiler, combining thermostatic radiator valves with individual consumption meters means you only pay for the heating consumed by your dwelling, which is much fairer than the proportional allocation by surface area used when meters are absent. This is often a mandatory upgrade for many communities due to European regulations. 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 (which happens every summer on the Costa Blanca when heating isn't used). To prevent this, it's advisable to move the thermostatic heads to their maximum and minimum settings every couple of months during the low season. If the valve is seized, the head is removed, the pin is freed with a very gentle tap, or the entire valve is replaced. Deep cleaning of the heating circuit water with a specific descaler to remove sludge and rust. This should be done every 7-10 years or when persistent cold spots occur.

Low water volume aluminium radiators are the most efficient for most modern installations. They heat up and cool down quickly, allowing precise time 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. The climate of the Costa Blanca influences everything related to gardens. Long, dry, and very hot summers, with little rain between May and September, and strong sun that stresses traditional lawns. A garden designed for Northern European climates, with lots of grass and soft-leaved plants, consumes a huge amount of water and suffers in July and August. That's why more and more clients are opting for low-water-use gardens. Decorative gravel, Mediterranean plants (lavender, rosemary, oleander, cacti, and succulents), palm trees, and olive trees. Annual gas boiler maintenance, between 90 and 130 euros with certificate included. Simple fault repair (sensor, valve, pressure switch), 80-180 euros plus parts. Complete replacement of a natural gas boiler with a condensing model, 1,400 euros including installation depending on brand and power output.
