Gas vs Electric Geyser: Which Is Better?
The short answer: a gas geyser costs less to run where gas pressure is good; an electric geyser is safer indoors and works when gas is off. If you want both, buy a gas + electric geyser.

Difference between gas geyser and electric geyser
- Fuel: gas geysers burn Sui gas or LPG; electric geysers use a 1500 to 3000 W element.
- Running cost: gas is usually cheaper per tank of hot water, as long as you do not waste it on a big pilot flame.
- Load shedding: gas geysers stop when gas is off; electric ones stop when power is off (a low watt model can run on a UPS or solar).
- Safety: gas geysers give off fumes and need a flue and fresh air; electric geysers need earthing and an ELCB.
- Installation: gas needs a gas line and an outside wall or ventilated place; electric needs only a strong socket and water pipes.
- Size: gas tanks come in 15 to 55 gallons for a whole house; electric tanks are usually 10 to 100 litres.
Gas bill vs electricity bill
Heating 50 litres of winter tap water to a hot shower temperature takes about 2.5 to 3 units of electricity on an electric geyser. A gas geyser does the same job with gas, which usually costs less, but an older tank geyser's pilot flame keeps burning day and night, and gas bills move into higher slabs as use goes up. An instant gas geyser avoids that waste. Full numbers: geyser electricity and gas bill.
Which geyser is safe: gas or electric?
Inside a home, an electric geyser with earthing and an ELCB is the safer choice, because it gives off no fumes. A gas geyser is safe when fitted outside or with a flue that takes fumes outdoors. Never use a gas geyser inside a closed bathroom. See which geyser is safe.
Our advice
- House with steady gas and several bathrooms: gas + electric geyser, such as Nasgas DEG-35 Super Deluxe 35 Gallon Gas + Electric Geyser.
- Flat, no gas, or gas off for long hours: electric geyser, such as Nasgas NEG-50 Litre Electric Geyser.
- Solar panels on the roof: low watt electric geyser.
- One bathroom with good gas: instant gas geyser.
