An electric hot water heater ranges in costs from about 300 to 700 while a gas heater ranges from 400 to 800.

Gas vs electric hot water heater efficiency.

Proper venting is critical. The higher the ef number. 2 gas tankless water heater pros and cons. Electricity has spent his career analyzing and understanding energy use including hot water heater energy savings and the differences between gas vs.

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. We saw a few differences in performance. If energy efficiency and saving money is your main concern you may also want to look into a gas tankless water heater. 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.

Rather than storing water tankless water heaters use heating coils to heat the water as you need it. Electric hot water heater cost and efficiency for the most part the choice boils down to understanding gas vs. Electric water heater operation costs. A gas water heater uses the heat from burning a fuel usually natural gas to heat water while an electric water heater uses electric resistance coils.

Figuring out the annual operating cost of a water heater involves consideration of the heater s efficiency and the cost of the fuel needed to run it. Gas water heaters are expensive to purchase. This mode prevents the water heater from automatically switching to electric resistance heating during times of high hot water demand. Gas heaters can have a higher capacity.

Lifetime energy cost is the sum of the discounted value of the annual energy costs based on assumed water heater life of 13 years. Operating costs tend to be lower. Installation can be complicated and expensive. 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.

The gas and the electric storage tank water heaters easily delivered a steady supply of hot water that reached our target temperature of 120 f. Gas heaters pose a. Michael bluejay aka mr. They re more energy efficient than a storage tank but provide only a limited flow of hot.
