Gas vs electric water heater cost (2026)
A 50-gallon gas tank runs about $2,400 installed in 2026. The same size in electric runs about $2,100 installed. Electric is cheaper to buy, but the operating cost gap depends entirely on local gas and electric rates.
Tank, natural gas
- ✓About half the operating cost of resistive electric
- ✓Recovers a 50-gallon tank in roughly 1 hour
- ✓Works through power outages on standing pilot models
- –Needs venting and combustion air
- –Carbon monoxide risk if vent corrodes or backdrafts
- –Slightly shorter average lifespan than electric tanks
Tank, electric
- ✓Cheaper unit and simpler install (no venting)
- ✓Electric tanks often outlast gas tanks by 2 to 4 years
- ✓Eligible for solar pairing or future heat pump upgrade
- –2x the operating cost of gas at average US rates
- –Slower recovery (about 20 gallons/hour for a 4500W element)
- –Stops working in a power outage

Pick Gas if
You already have natural gas at the home and care about operating cost.
Pick Electric if
You have no gas service, are pairing with solar, or are planning to upgrade to a heat pump water heater in the next swap cycle.

What about heat pump electric instead of resistive?+
A heat pump water heater cuts electric operating cost by 60 to 70 percent and lands close to gas on annual cost. Install is 1.5x to 2x a resistive tank, but the federal 25C credit covers 30 percent up to $2,000.
Is converting gas to electric a good idea?+
Only if you're pre-wiring for solar, electrifying the whole house, or replacing a failed gas unit in a home without working venting. Otherwise the operating cost penalty makes a like-for-like gas swap simpler.
Does gas water heater install need a permit?+
Yes in nearly every US jurisdiction. Permit and inspection run $50 to $200 and protect the manufacturer warranty plus your home insurance posture.
