Compare gas and electric tankless water heaters.

Top electric and gas heaters on the market. At present a natural gas tankless water heater is about 10 15 cheaper to operate than an electric tankless heater. This is almost 2 times the price of an electric tankless water heater. A good sized electric tankless water heater goes for around 500.

However it is not as simple as comparing the cost of operating an electric and gas tankless water heater based on today s energy prices. 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. A gas heater must vent the spent gas which also takes some of the heat with it. Similarly electric heaters can have higher energy factor ratings than gas heaters.

All this can offset the higher cost of electric power to some extent. While gas hot water heaters cost less to run due to the lower cost of natural gas electric heaters are actually more efficient. Electric tankless water heaters are way cheaper than their gas fuelled competitors. For a good sized gas fuelled tankless heater costs between 1000 and 1200.

This is due to the way that the heaters operate. 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. Electric water heaters tend to have at least 98 thermal efficiency many are 99 percent or more.
