Common water heater problems
Unit not firing — could be the thermostat, heating element, or gas ignition depending on the type.
Often a sign of limescale build-up on the element or heat exchanger, common with hard water.
Undersized tank for the household, or the element only partially working.
Can mean a failing tank (needs replacement) or just a loose fitting (quick fix).
Popping or banging sounds usually mean limescale sediment building up inside the tank.
Could be a faulty thermocouple or a draft issue — worth a proper look before assuming the worst.
Water heaters in Mijas Costa — what to expect
Costa del Sol water is hard, and Mijas Costa is no exception — limescale is the number one cause of water heater failure here, working faster on units that never get descaled. A lot of properties still have their original heater from the 1990s or early 2000s, which is well past the point where repair makes financial sense.
If your unit is under warranty or was installed recently, most faults are a straightforward fix. If it's older and the tank is corroding rather than just scaled up, we'll tell you that upfront rather than patching something that's about to fail again.

FAQ — water heater Mijas Costa
Why do boilers fail so often in Mijas Costa?+
Hard water is the main reason. Limescale builds up on the heating element or heat exchanger over years, which makes the unit work harder until it eventually fails or stops heating properly.
Is it worth repairing or should I replace the unit?+
Depends on the age and the fault. If it's over 10 years old and the tank itself is corroding, replacement is usually more cost-effective. We'll tell you honestly which makes sense.
Can you fix electric and gas water heaters?+
Yes, we cover both — electric immersion heaters, thermos-style water heaters, and gas combi boilers common in this area.
How fast can someone look at it?+
No hot water isn't usually a same-hour emergency, but we treat it as a priority — most requests get a visit within a day or two, faster if marked urgent.
