❓ Frequently Asked Questions

Q: Is a burning smell from geyser dangerous?
Yes, it can be very dangerous. Electrical burning smell indicates potential short circuit or fire hazard. Plastic/rubber burning suggests component overheating. Dust smell from new geyser is normal, but electrical burning smell requires immediate power cutoff and professional inspection. Never ignore electrical burning odor - it can lead to fire.
Q: New geyser burning smell - is this normal or a problem?
Normal if it's a light dust smell. New geysers often have manufacturing residues, protective coatings, or dust on heating element that burn off during first 2-3 uses. This creates a light, dissipating smell. Ventilate room and monitor - it should disappear after a few cycles. However, if smell is strong electrical/plastic burning, or persists beyond 3 uses, call technician immediately.
Q: How to tell if geyser smell is electrical or just dust?
Electrical burning smell characteristics: Acrid, sharp, plastic/rubber melting odor, often accompanied by MCB trips, indicator light flickering, or buzzing sounds. Persists or gets worse. Dust burning (normal): Light, similar to heater first use, dissipates after 2-3 cycles, no other symptoms. If in doubt, turn off MCB and call electrician - better safe than sorry.
Q: Can burning smell from geyser lead to fire?
Yes, electrical burning smell is a fire hazard. Short circuits, arcing connections, burnt insulation, and overheating components can ignite fire. Geysers in bathrooms pose higher risk due to moisture. If you smell electrical burning, immediately: 1) Turn off MCB, 2) Evacuate if smell is strong, 3) Have fire extinguisher ready, 4) Call electrician. Do NOT use geyser until professionally inspected and cleared.
Q: Why does geyser smell when first turned on after months?
Dust accumulation on heating element. When geyser sits unused for months (summer season), dust settles on element and surrounding parts. When first heated, this dust burns off creating smell. Usually harmless and dissipates quickly. However, if smell is strong electrical/plastic, or persists, it could indicate component degradation during storage. Monitor for 2-3 cycles; if continues, get professional inspection.
Q: What is the cost to fix geyser electrical burning smell?
Depends on cause: Electrical wiring repair: ₹800-₹3,000 | Heating element replacement: ₹800-₹2,500 | Control board/PCB replacement: ₹1,500-₹4,000 | Thermostat replacement: ₹500-₹1,500 | Complete electrical inspection: ₹500-₹1,000 | Voltage stabilizer installation: ₹1,500-₹4,000. For old geysers (10-12+ years), replacement may be more economical than major repairs.
Q: Should I replace old geyser if it has burning smell?
Yes, if geyser is 10-12+ years old. Old geysers develop multiple issues: degraded insulation (PUF charring), corroded wiring, worn components, scale buildup. Burning smell in old units often indicates end-of-life. Repairing may cost 40-60% of new geyser price. Consider replacement for: Better energy efficiency, improved safety features (ELCB, auto-cutoff), warranty coverage, and peace of mind. Modern geysers have better electrical safety standards.
Q: Geyser has burning smell but still works - is it safe to use?
No, NOT safe to use. Just because geyser heats water doesn't mean it's safe. Burning smell indicates underlying electrical/component issues that worsen over time. Continued use can: Escalate to short circuit, Cause fire, Lead to electric shock risk, Damage expensive components beyond repair. Turn off MCB immediately and get professional diagnosis. Don't prioritize hot water over family safety. Use alternative heating methods until repair is completed.
