Can you install a tankless water heater next to an electrical panel?
The only code requirements I’ve found regarding clearances around an electrical panel are allowing at least a 30″ working space (side to side).
Do you need a dedicated circuit for a tankless water heater?
A tankless water heater will require a dedicated circuit as specified by the installation manual of the unit that has been selected. If you need additional space in the panel for the circuit breaker then a quad circuit breaker may be allowed as specified by the make and model of the panel.

How do you hook up a tankless hot water heater?
Quote from the video:
Quote from Youtube video: Two is gonna be a white one L 2 now these are both off the same breaker both these wires are off the same breaker. They go to the same unit here and those that goes to the to the heater element.
How close can water heater be to panel box?
Water heaters require clearance in front of them at the service side also. A gas water heater needs a 30-inch by 30-inch area, per International Residential Code (IRC M1305.
How far does electrical panel have to be from water heater?
Basically, the panel can be anywhere in the 30″ width working space. There is no mention of center of the panel or otherwise. Meaning, the panel can be at the extreme side of the 30″ space as long as the space is clear for 30″.
Does a tankless water heater need a GFCI breaker?
Most tankless water heaters are placed outdoors. The attachment plug serves as the disconnect and the receptacle shall be protected by GFCI. If there’s a new circuit that serves only exterior receptacles, no AFCI is required. If the receptacle is added to a circuit, there’s most likely a requirement for AFCI.
Do tankless water heaters need to be hardwired?
It can be plugged into an outlet or wired directly to a service panel. An indoor, electric tankless water heater does not need to be vented to the outside. It does require 240-volt power. It may be plugged into a 240-volt outlet or directly wired to a service panel.
What size breaker does a gas tankless water heater need?
A gas tankless water heater only needs a 15-amp, 120 volt dedicated single-pole breaker for this purpose.
How do you install a whole house electric tankless water heater?
Quote from the video:
Quote from Youtube video: The entire process only took a few hours and that's with installing two tankless water heaters.
Can I use a 40 amp breaker for water heater?
With our answer, a 40-gallon water heater needs at least a 25-amp breaker, the closest to the amperage value. However, I highly recommend using 30-amps for a safer breaker size. Meanwhile, an 80-gallon heater powered by 5500 watts and 240 volts, will result in 5500W/240V x (1.25 continual load) = 28.64 amps.
Is 200 amp service enough for tankless water heater?
A 200-amp service allows operation of multiple appliances at once, while a 60-amp service won’t provide enough power to run an electric hot water heater, air conditioner and hair dryer simultaneously. The EcoSmart Eco-18 model requires two 40-amp breakers for installation and has a 75-amp draw.
How many amps does a tankless water heater pull?
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 happens if you oversize a breaker?
Fuses burn literally, breakers safely discontinue the circuit. If they are oversized, they may not be the weakest points anymore. In case of failure they won’t be the first to burn – it may be the most expensive device you own or, even worse, it may be a conductor in the wall.
How much can you oversize a breaker?
It is ok to oversize the wire as long as the breaker is not over sized. If your shop was 75 feet from the panel, then upsizing the wire to #4 combined with the 50 amp breaker would be proper. Larger wires have less voltage drop. Longer runs require larger wires to prevent excessive voltage drop.
Are oversized breakers safe?
Oversizing a circuit breaker can be a safety concern. If there is a direct short in an appliance a breaker will kick off even if oversized, but if there is simply a crossed or burned wire it may not turn off. This would cause a possible shock hazard.
Are bigger breakers better?
When the breaker is tripping, it is almost never a good idea to replace it with a larger one. Here’s why: It increases the risk of fire. If the breaker is tripping because it’s overloaded (say, drawing 25 amps on a 20-amp breaker), increasing the size may cause the wire or the receptacle to overheat.
Can I replace a 20 amp circuit breaker with a 30 amp?
The answer is, “No, do not put a 30 Amp breaker in place of a 20 Amp breaker because the wiring is most likely’sized’ for the 20 Amp load and -may- overheat if a 30 Amp load is used with wiring sized for a 20 Amp load.”
What size wire should I use for a 30 amp breaker?
For a maximum of 30 amps, you’ll need a wire gauge of 10. The most common household item that requires a 30 amp circuit is a central air conditioner.
