For homes that are empty from October to March, the service also includes technical shutdown. We close the main water valves if there's no risk of frost, which is rare on the coast. We drain the water heater if the property is unused for over three months. We empty the air conditioner drip trays and set them to 'off'. We also check smoke and carbon monoxide detectors, if present.

In reality, very few people replace them proactively. Service technicians rarely inform customers about them, and owners are often unaware of their importance. When we conduct an initial inspection of a water heater over five years old, the anode is almost always completely consumed. Almost nobody knows it exists, but it's the part that adds the most lifespan to your water heater. It's a magnesium rod inside the tank that attracts corrosion away from the tank walls. It gradually depletes over time. Once it's fully consumed, corrosion begins to attack the tank itself, and from then on, every year counts. We recommend replacing it every four to five years in hard water areas. It's a reasonable cost that can easily extend the appliance's life by ten years. The water takes longer to heat than it did in the first year. It comes out hotter initially and then cools down quickly. You notice an unusually high electrical consumption on your bill. There are boiling-like noises, indicating sediment buildup at the bottom of the tank. The water may appear slightly cloudy for the first few seconds. Any of these symptoms warrant an inspection.

As this is a professional installation with an invoice, the manufacturer's official warranty (2-5 years depending on the brand) is maintained. We also 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 special care, will last between five and eight years before developing serious issues. Compared to an identical water heater installed in soft water areas like Galicia or northern Catalonia, where they can last twelve to fifteen years without problems, the difference is stark and ultimately costly. 30 days on labour and the manufacturer's official warranty on the installed appliance.

The price for a water heater replacement in Cervelló typically ranges from €59 to €420 as a guideline. The final cost depends on the property's condition, materials, and labour time, which we will confirm after reviewing photos or conducting an on-site assessment (no obligation). In this area, the market average for similar jobs is around €150; we are often 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 practical option. For villas or homes with available natural gas, the choice between a larger electric model and a gas combi boiler depends on family consumption and the current prices of gas versus electricity. The cost of scheduled maintenance is always less than the accumulated cost of reactive emergency repairs. Our client data confirms this year after year.
