How much power does a gas tankless water heater require?
Most tankless gas water heaters require a 15 ampere or 20-ampere 120-volt circuit to power the electric pilot light and the control board. The National Electrical Code requires instantaneous water heaters to have circuits not exceeding 120 amperes and protected at not more than 150 amperes.
How much electric does a gas tankless water heater use?
How much does it cost to run it? Solution: 20 kW heater will spend 20 kWh worth of electricity if you run it for 1 hour. The average kWh price in the US is $0,1319. That means a 20 kW tankless heater will spend, on average, 20 kWh x $0,1319 per kWh = $2,64 per running hour.
