How much power doesatanklesswaterheater use?
When they are 'on', electrical tankless heaters require up to 30,000W of electricity. For comparison, an average washing machine will require a bit more than 1,000W to run (and it will run for 1-2h). However, electric tanklesswater heaters are not running all the time.
How many amps doesatankless gas waterheater use?
One whole-house tanklesswaterheater has four 7,000-watt elements, for a total electrical load of 28,000 watts. This load re- quires wire and a circuit breaker that will handle at least 120 amps, at a cost many times that of electrical service to a conventional tank water heater.
Do tanklesswater heaters use more electricity than regular water heaters?
Tankless heaters can be 24-34% more energy-efficient than regular water heaters for households that use 41 gallons or fewer of hot water daily. Tankless heaters can be 8-14% more energy-efficient for households that use around 86 gallons daily.6 באוק׳ 2016

Do tanklesswater heaters pay for themselves?
Tankless water heaters can eventually pay for themselves with energy bill savings, but the payback period may be long: 22-27 years for a gas tankless heater, 12-20 years for an electric. Tankless water heaters tend to last longer than storage heaters: 20 to 25 years in many cases.
Is atanklesswaterheater worth the expense?
Tankless water heaters save money in the long run, but initial costs are higher than tank models. The U.S. Department of Energy estimates gas-fired tankless heaters save an average of $108 in energy costs per year over their traditional tank counterparts, while electric tankless heaters save $44 per year.12 בדצמ׳ 2016
Can you run out of hot water with atanklesswater heater?

Does it take electricity to run a gas water heater?
Gas water heaters utilize a continuously running pilot light and should work in a power outage. Electric is hooked up to the gas waterheater in order to create the spark for the pilot light to activate. So, electricity is not necessarily needed for the gas waterheater to function properly.31 באוג׳ 2021
Do gas-powered tanklesswater heaters need electricity?
