Electric vs natural gas hot water heater.
If we use 65 gallons of hot water daily a natural gas water heater with an ef of 82 and a fuel cost of 0 00000295 btu.
You can find a high quality electric water heater for as little as 500.
A gas or electric water heater s energy factor ef is a measurement that compares the amount of hot water the heater produces per day to the amount of fuel it consumes.
They work one of two ways.
An electric hot water heater ranges in costs from about 300 to 700 while a gas heater ranges from 400 to 800.
An electric water heater through an energy factor of 2 0 and an electricity cost of 0 1041 kwh.
Before you decide that gas is the winner in the natural gas and propane vs electric hot water heater debate you need to consider the pros and cons of electric heaters.
Natural gas water heaters typically use less energy and cost less to run by about half than electric water heaters although you should note that gas models cost more at the time of purchase.
Traditional water heaters natural gas and oil fired have an energy factor ef of 53 to 70.
The higher the ef number.
According to energy gov an electric heat pump water heater might have lower energy costs because of its higher efficiency than a gas fired conventional storage water heater even though local natural gas costs might be lower than the electricity rates.
By meeting ef standards they can be considered energy efficient.

Direct systems heat water in tubes inside the collector then send the water to a storage tank for later use.
A storage tank and a back up source of hot water either a gas or electric tank water heater to ensure a supply of hot water on cloudy and cold days.
Gas water heaters are less energy efficient than electric heaters but the cost of electricity itself makes the running costs of an electric heater higher.
Comparatively energy efficient gas water heaters have an ef of 67 or higher while energy efficient electric water heaters have an ef of 2 00 or 2 20 depending on tank size.
Even top range electric heaters cost little more than 700.
For most it is easiest to replace with the same type of tank that was connected previously as opposed to changing over from electric to gas due to using existing pipelines.
A gas water heater that is powered by natural gas or propane is the other popular choice for water tanks.
