Few appliances work harder in a Maltese home than the water heater — and few die younger. The island's very hard water scales up heating elements and tanks years ahead of what manufacturers promise. Knowing the difference between a €40 fix and a heater at the end of its life saves both cold showers and wasted money.
The usual suspects, symptom by symptom
No hot water at all
Usually the heating element or the thermostat. Both are standard repairs. If the trip switch on your electrical panel also fired, the element has likely blistered and shorted — a classic hard-water death, and a straightforward replacement for a plumber or electrician.
Water is lukewarm or runs out fast
Scale. A layer of limescale on the element makes it heat the scale instead of the water, and a scaled tank effectively shrinks — a 80-litre geyser behaving like a 50-litre one is telling you what is inside it. Descaling helps if caught early; a heavily scaled tank is usually not worth opening.
The safety valve drips constantly
The pressure relief valve on Maltese geysers weeps by design when heating, but a constant drip means either a failing valve (cheap) or excess mains pressure (needs a pressure-reducing valve). Do not cap it or block the outlet — that valve is what stops a sealed tank becoming dangerous.
Water around the base of the unit
If the tank itself is leaking, the heater is finished. Tanks rust from the inside once the protective lining or anode is gone; no repair outlasts a month. Close the heater's inlet valve, switch it off at the breaker, and plan a replacement.
Repair or replace: the honest maths
| Situation | Sensible move |
|---|---|
| Element or thermostat failure, unit under 8 years | Repair (€60 – €130 with parts) |
| Scaled but sound unit | Descale and fit a new anode (€80 – €150) |
| Tank leaking | Replace |
| Unit over 10 years with any fault | Replace — the next fault is already queued |
A new geyser in Malta costs roughly €150 to €400 for the unit depending on size and brand, plus €80 to €200 installation. See our plumber price guide for how installation quotes break down.
Make the next one last longer
- Fit a magnesium anode and replace it every 2–3 years. It corrodes so the tank does not. It is the single cheapest life-extender for a Maltese geyser.
- Set the thermostat to about 60°C. Hotter accelerates scaling; much cooler risks legionella.
- Drain a few litres through the valve twice a year to flush loose scale off the bottom of the tank.
Getting it fixed
Post the symptoms — plus a photo of the unit and its label — on Qabbad's plumber page and approved plumbers covering your locality reply with quotes. For electric geysers with suspected electrical faults, an electrician may be the right trade; describe the symptoms and let the providers tell you.
Frequently asked questions
How long does a water heater last in Malta?
With Malta's hard water, 8 to 12 years is a realistic lifespan for a standard electric geyser — less if the anode is never replaced. The same unit in a soft-water country might do 15.
How much does it cost to replace a water heater in Malta?
Budget €150 to €400 for the unit and €80 to €200 for installation, depending on size, access and whether pipework needs adapting. Like-for-like swaps sit at the lower end.
Is a dripping safety valve dangerous?
Occasional weeping during heating cycles is normal. A constant drip needs attention — but the dangerous mistake is plugging the valve to stop the drip. Never block a pressure relief valve.
Can I replace a heating element myself?
It involves draining the tank, working on both plumbing and 240V electrics, and resealing against mains pressure. Legally and practically, this is a job for a professional in most households.
