Does a gas tankless water heater need a dedicated circuit?
Does a gas tankless water heater need a dedicated circuit?
The electrical requirements for Takagi tankless water heaters are 120 V AC 60 Hz and draw less than 2 Amps. The outlet needs to be on a dedicated circuit and should not exceed 70% capacity in terms of power consumption or else the breaker will trip.Aug 4, 2021
How many amps does gas tankless water heater use?
Tankless heaters can draw anywhere from 42 amps to 167 amps. We can calculate exactly how many amps does a tankless water heater because we know two key factors: Overall power or wattage. Electric tankless water heaters can have a power input from 10,000W (10 kW) to 40,000W (40 kW).
What size breaker do I need for a gas tankless water heater?
Usually, it's about 12 amps and less than 120 volts. Gas tankless water heaters need a minimal amount of electricity to power the electronic ignition system. A gas tankless water heater only needs a 15-amp, 120 volt dedicated single-pole breaker for this purpose.Jun 17, 2021
What kind of wire do I need for a tankless water heater?
You must utilize either a 120- or 240-volt circuit, wholly devoted to the heater. Both voltages require 8-gauge wire, and the section exposed to the area under the sink must be armored cable. If the manufacturer's instructions call for a larger cable, the National Electrical Code says you must comply.
