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.
Electric vs natural gas hot water heater.
A gas water heater that is powered by natural gas or propane is the other popular choice for water tanks.
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.
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.
The higher the ef number.
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.
Installation costs for an electric heater are 700 to 1 000 while the cost to install a gas heater ranges from 1 000 to 2 000 depending on whether you have an existing gas line and vent.
Traditional water heaters natural gas and oil fired have an energy factor ef of 53 to 70.
Direct systems heat water in tubes inside the collector then send the water to a storage tank for later use.
365 x 41045 82 x 0 00000295 53 89.
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.
Even top range electric heaters cost little more than 700.
You can find a high quality electric water heater for as little as 500.
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.
The initial investment is low.
365 x 12 03 2 0x 0 1041 228 54.
An electric water heater through an energy factor of 2 0 and an electricity cost of 0 1041 kwh.
By meeting ef standards they can be considered energy efficient.
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.
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.
