What size breaker do I need for a 80 gallon water heater?
30-amp
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. Meaning, a 30-amp dedicated circuit breaker is enough.
How many amps does a 80 gallon hot water heater draw?
A water heater will only draw depending on the wattage of the element(s). So your WH has 2 – 4500 watt elements. When only one runs it is drawing about 22 amps (208 is nominal voltage which is what you have in your building) 4500/208= 21.6 amps.
How many amps does an electric water heater need?
18.8 amps
Most electric water heaters use 18.8 amps with 240 volts and a 4,500 watt heating element. A gas water heater uses less amps—about 12 Amps with 115 volts. The average residential container heater has a 40-gallon tank and usually requires a 30-amp breaker.
Does a water heater require 220 volt power?
Voltage Requirements Most electric hot water heaters operate on 220 to 250 volts AC. This voltage in homes requires a double circuit breaker rated for the amperage draw of the hot water heaters.
Can I use a 40 amp breaker for a water heater?
In general, NO. Doing so is very dangerous and could start a fire! 10 gauge wire requires at most a 30A breaker, whereas 8 gauge requires at most a 40A breaker.
What size breaker do I need for a 240-volt water heater?
A 240-volt dedicated circuit is needed for electric water heaters to work. A 30-amp double-pole breaker and 10-2 non-metallic cable are included in the circuit wiring.
Can I use a 40 amp breaker for water heater?
How many amps does a 50 gallon electric water heater use?
18.75 amps
A typical 50 gallon electric water heater runs at 4500 watts. In an electric circuit of 240 volts, 4500 watts is equivalent to 18.75 amps.
What size breaker is needed for a 50 gallon electric water heater?
The standard for water heater circuits is #10, two conductors with ground (10/2) and a 30 amp circuit breaker for a water heater.
Will a 220 water heater run on 110?
If you are trying to run a 110v 1500 watt heater from 220v, you need a step-down transformer of at least 1500w rating. If you are trying to run a 220v 1500 watt heater from 110v, you need a step-up transformer of at least 1500w rating. The rating is still “at least 1500w”.
What size breaker do I need for an electric hot water heater?
Electric water heaters require a 240-volt dedicated circuit, which serves only the water heater and no other appliances or devices. The circuit wiring typically includes a 30-amp double-pole breaker and 10-2 non-metallic (NM) or MC cable.
How much energy does an 80 gallon water heater use?
Depending on the services offered by local utility providers, it can provide Demand Response, Energy Storage and Time of Use savings benefits. With a 80-gallon (nominal) tank delivering 5,500 watts, the EG6-80-DRRT delivers a first hour rating of 80 gallons at an Uniform Energy Factor of 0.93.
How many watts does an electric water heater use?
Exactly how many watts an electric water heater uses depends on a number of variables, including the age and size of the unit, whether it is a tank or on-demand model, what temperature you set it to, how much hot water you use in a day, and other factors.
How much energy does a tankless water heater use?
Generally speaking, these units will consume less energy than a traditional hot water heater, although how much electricity tankless water heaters use will still depend on the demand you create in your home. Since they don’t need to heat water when you aren’t using them, tankless heaters may only run for two hours a day or so.
What happens if my 80 gallon hot water heater falls over?
An 80-gallon tank filled with hot water can make a mess if it ever falls over, so it’s important that the unit be properly leveled on a stable surface. It must be strapped to the framing if you live in a seismic area. If you have a gas unit, you must vent it, and that may affect where you place it.
