For homes left empty from October to March, the inspection also includes technical shutdown. We close water stopcocks if there's no risk of frost, which is rare on the coast. We purge the water heater if the home is unused for more than three months. We empty air conditioner trays and switch them off. And we check smoke and carbon monoxide detectors, if any.

If it is over eight years old, in hard water areas, the appliance is at the end of its useful life. Although the current fault can be repaired, the next one will appear in one or two years. It is more cost-effective to replace it and start fresh with new equipment and maintenance from the beginning. The reason is the scale that accumulates inside the tank. The electric heating element that heats the water becomes coated with an increasingly thick layer that acts as an insulator. The thermostat detects that it is not reaching the target temperature and sends more current. The bill goes up, the appliance heats less effectively, and eventually the heating element burns out. Sometimes the tank bursts from the inside, leading to a catastrophic leak that floods the laundry room. The reality is that nobody replaces it. Technical services usually don't advise it, and owners are unaware of its existence. When we perform a first inspection on a water heater over five years old, the anode is almost always completely consumed.

As 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. Oversizing penalises the electricity bill because the appliance spends more on keeping a volume hot that you never use. Undersizing results in cold showers at the end of the morning family rush. We calculate needs before proposing a model. The water on the Costa Blanca has an average hardness of 30-40 French degrees. This means that a standard electric water heater of any brand, installed without any special care, lasts between five and eight years before starting to give 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 huge and ultimately affects your wallet.

The price for water heater installation and repair in Sant Joan Despí typically ranges between €59 and €420. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. For holiday apartments or small properties without a gas connection, an electric water heater is the only reasonable option. For villas or homes with natural gas available, the choice between a larger capacity electric heater and a combi gas boiler depends on family consumption and the current price of gas versus electricity. Timed maintenance always costs less than the accumulated cost of reactive emergencies. The data we collect from our own clients confirms this year after year.
