Short answer: the Bajaj Majesty Duetto 6 litre is the gas geyser I would buy: an oxygen depletion sensor, child lock and Bajaj service. For the most safety layers, the Racold 6L ODS-ECO+. For weak water pressure, the Havells Flagro.
Gas geysers make sense when power cuts are long or the wiring cannot handle a 3 kW geyser. They heat water as it flows, so there is no tank to wait for. But they burn LPG, and that is a safety question before it is a features question. Prices change every week during sales, so live prices sit in the buy buttons, not in the text.

How I ranked them
The Geekman Score
Geekman has covered home appliances for over 10 years. A gas geyser is the one appliance where I put safety ahead of everything, so the ranking leans on safety features first: an oxygen depletion sensor, flame-failure cut-off, solenoid valves and child lock. Then flow, warranty and service. Every pick gets a Geekman Score out of 10: Heating 25%, Safety 15%, Service 20% and Value 40%.

Full review
A gas geyser heats water as it flows, using LPG instead of electricity. That is great when power cuts are long or the wiring cannot take a 3 kW geyser. The Majesty Duetto has the safety feature I insist on: an oxygen depletion sensor that shuts the gas if the room runs low on oxygen.
Installation. Fit it outside the bathroom or in a very well-ventilated spot, with the cylinder outside. Use only the brand technician.

Gas geysers need a minimum water flow to light. The Flagro is designed to work at low pressure, which helps in homes with weak overhead tank flow.

1 · Never in a closed bathroom
A gas geyser burns oxygen and gives off carbon monoxide, which has no smell. Install it outside the bathroom or near a large window or exhaust fan, never in a small closed bathroom. Keep the LPG cylinder outside the bathroom.
2 · Insist on an oxygen depletion sensor
An ODS shuts the gas when oxygen in the room drops. It is the single most important feature on a gas geyser.
3 · Use the brand technician
Use the brand’s technician, an ISI gas hose and a proper regulator. Check the hose every year and replace it when it cracks.
Questions other guides skip
1 · Is a gas geyser safe?
It is safe with an oxygen depletion sensor and proper ventilation. Most accidents happen in small closed bathrooms with no ventilation.
2 · Gas or electric geyser: which costs less to run?
At today’s LPG and power prices, running costs are close. Pick gas for power cuts or weak wiring, electric for convenience and safety.
Also consider
Have reliable power? An electric storage geyser is simpler and safer.
