Warm Flow Lab exists to make home water heaters and geysers less confusing and a lot safer. We help homeowners and hands-on DIYers across India make confident, practical decisions about installing, maintaining, and troubleshooting their water heater, without the hype, the jargon, or the recycled advice you find everywhere else.
Our mission
Hot water should be simple and safe. Too much of what you read online about geysers is vague, copied, or written by people who have never held a spanner. We publish clear, tested, people-first guidance grounded in real hands-on experience, the clearances that actually matter, why units fail early on hard water, and how to wire, earth, and vent a heater so it is genuinely safe.
What we cover
Everything is organised into six focused areas so you can go deep on exactly what you need:
- Installation, mounting, connections, wiring, clearances, and getting a new or replacement geyser fitted correctly.
- Maintenance, flushing, descaling, anode rods, and the upkeep that beats India’s hard water.
- Safety, earthing, ELCB/RCCB, pressure relief, and gas-geyser ventilation.
- Buying, storage vs instant, capacity sizing, star ratings, and comparing electric, gas, and solar.
- Repairs, diagnosing no-heat, leaks, tripping, and noisy units.
- Efficiency, thermostat settings, insulation, and cutting your electricity bill.
