GAS vs ELECTRIC WATER HEATERS
Water Heaters are a key appliance in the modern home, so confronting the question of what kind of heater to get is a must in replacements, remodeling jobs and new home construction.

Cost of Use
The typical gas water heater can heat 50 gallons of water from 55 to 105 degrees F for about 17 cents. A 4500 watt electric water heater does the same job for about 49 cents.
The same gas water heater requires about 30 minutes to heat about 40 gallons of water from 55 to 105 degres F. The same 4500 watt electric water heater will need twice as long.
Gas water heaters use steel tanks with glass or ceramic linings that are prone to corrosion. Electric heaters can use plastic tanks that are not prone to corrosion.
