FAQ
Is 60 amps enough for a tankless water heater?
A typical tankless water heater requires a 40-50 amp breaker for each wire that supplies one heating element. In the mentioned example, three breakers of this rating are needed, resulting in a total of 120+ amps. However, the main breaker for the house is usually 150 amps, and to ensure safety, it is recommended to use only 80% of its capacity, which amounts to 120 amps. This means that there is no electricity left to power other appliances.
How many amps is a 240V water heater?
The typical electrical water heater operates at 18.75 amps when connected to a 240-volt power source. The wattage rating for most electric heaters is around 4500 watts, although this can vary between different models.
Is 30 amp enough for water heater?
In North America, the majority of regular full-size tank-type electric water heaters need a 30 ampere 240 breaker with two poles. However, if you have a fast-recovery electric water heater or a tankless electric water heater, you might require a larger circuit breaker.
Can a 200 amp service handle tankless water heater?
Tankless water heaters require a power draw of 15-20 amps, and most houses with a 200 amp panel should have sufficient capacity to accommodate them. However, it’s important to note that these heaters have a higher power demand than that. To effectively operate a shower with an inlet water temperature of 50 degrees, you will need a minimum power draw of 80 amps.
