Vlorë's water is hard, and limescale is the silent killer of electric boilers: it coats the heating element until it overheats and burns out, and it builds up in the tank until capacity shrinks and the unit runs constantly. Add the humid coastal winter — when the boiler works hardest and cold damp air corrodes connections — and you understand why January is our busiest repair month.
The second typical failure is the thermostat, which drifts until water is lukewarm or scalding. The third, more serious, is the tank itself: once corrosion perforates it, repair is not possible and replacement is the honest answer. We tell you plainly which case you are in before you spend anything.
