If the heater is under four years old, repair almost always makes sense. Replacing element and anode is a quick intervention that restores factory characteristics. Five to eight years old: it depends. If the fault is the element and the rest is in good shape, repair. If there’s a tank leak or internal weld leak, replace, the leak will return at another point soon. Over eight years in hard water, the unit is at the end of useful life. Even if today’s fault is repairable, the next one will arrive in a year or two. Replacing makes more sense.

The reality is that almost nobody changes it. Service techs rarely warn and owners don’t know it exists. When we do a first service on a heater older than five years, the anode is almost always fully consumed. For holiday flats or smaller properties without a gas supply, electric is the only sensible option. For villas or homes with natural gas, the choice between a larger electric unit and a combi gas boiler depends on family demand and the current gas/electricity price ratio. Electric has the advantage of simplicity: plug in and heat. No mandatory annual service (unlike gas boilers, which require it by law). Its limit is capacity: once the tank is empty, you wait 1-2 hours for it to reheat. For a family showering several kids in succession, that can be a problem.

For a one-person flat, 50 litres is enough. Couple without kids, 80 litres. Family of 3-4, 100 or 150. More than four or two simultaneously-used bathrooms, 200 litres or gas. Installation, replacement and repair. Limescale removal, sacrificial anode and element. Diagnosis before quoting. We assess whether repair or replacement makes sense based on age, tank condition and the fault detected.

El precio de impermeabilizado en Sant Genís dels Agudells suele moverse entre 227 y 2925 euros. El número final depende del estado del inmueble, los materiales y el tiempo de trabajo. Siempre damos el presupuesto cerrado antes de empezar. 30 days on labour plus the manufacturer’s official warranty on the installed unit. Water on the Costa Blanca runs at 30-40 French degrees of hardness. That means a standard electric water heater of any brand, fitted with no special precaution, lasts five to eight years before serious problems start. Compared with the same unit installed in soft-water regions like Galicia or northern Catalonia, where it easily reaches twelve or fifteen years, the difference is brutal and ends up costing real money.
