For homes that are empty from October to March, the inspection also includes a technical shutdown. We turn off the main water valves if there's no risk of frost, which is rare on the coast. We'll purge the water heater if the property is unused for over three months. We'll empty the air conditioner trays and leave them in the 'off' position. And we'll check smoke and carbon monoxide detectors, if present.

The reality is, nobody changes it. Service technicians usually don't mention it, and owners are unaware of its existence. When we perform an initial inspection on a water heater over five years old, the anode is almost always completely consumed. Almost no one knows it exists, but it's the part that adds the most useful life to the water heater. It's a magnesium rod inside the tank that attracts corrosion to itself instead of letting it attack the tank walls. It gets consumed over time. When it's fully depleted, corrosion starts eating away at the tank, and from then on, every year counts. We recommend replacing it every four to five years in hard water areas. It's reasonably priced and easily extends the appliance's life by ten years. The water takes longer to heat than in the first year. It comes out hotter initially and then cools down quickly. You notice abnormally high electricity consumption on your bill. There are noises like a kettle boiling, indicating bubbling at the bottom of the tank due to sediment. The water runs slightly cloudy for the first few seconds. Any of these symptoms warrant an inspection.

As it's a professional installation with an invoice, the manufacturer honours its official warranty (2-5 years depending on the brand). We add a 30-day warranty on our labour. The water on the Costa Blanca has an average hardness of 30-40 French degrees. This means a standard electric water heater of any brand, installed without any special care, lasts between five and eight years before starting to cause serious problems. Compared to an identical water heater installed in soft water areas like Galicia or northern Catalonia, where it lasts twelve to fifteen years without issues, the difference is stark and ends up costing you more. 30 days on labour and the manufacturer's official warranty on the installed appliance.

The price for boiler and water heater service in Teià typically ranges between €59 and €420 as a guideline. The final figure depends on the property's condition, materials, and time required, and we always finalize it after reviewing photos or — if you prefer — an on-site assessment, with no obligation. In the area, the market average for similar jobs is around €150; we are usually below this when the property's condition allows. For holiday apartments or small homes without a gas connection, an electric water heater is the only viable option. For villas or homes with natural gas available, the choice between a larger electric model and a gas combi boiler depends on family consumption and the current price of gas versus electricity. The cost of programmed maintenance is always lower than the accumulated cost of reactive emergencies. The data we've collected from our own clients confirms this year after year.
