What Size Breaker For Tankless Water Heater
The size of the breaker you need depends on the wattage of your tankless water heater. Most tankless water heaters have a wattage between 12,000 and 27,000 watts. To find the right size breaker for your heater, check the manufacturer’s documentation or look for a sticker on the back of the unit. If your water heater is over 27,000 watts, you’ll need to use a breaker rated for more than 30,000 watts.
It’s also important to consider the amperage of your tankless water heater. Most tankless water heaters have an amperage of between 15 and 20 amps. To find the right size breaker for your heater, add the wattage and amperage of your water heater. For example, if your water heater has a wattage of 18,000 and an amperage of 15 amps, you need a breaker rated for at least 33,000 watts (18,000 + 15 = 33,000).
When choosing a breaker, it’s important to buy one rated for more than the wattage and amperage of your water heater. This will give you some wiggle room and help prevent an overload on your electrical system.
If you’re unsure which breaker to choose, talk to a professional electrician. They can help you choose the right breaker for your tankless water heater and install it properly.

Tankless water heaters are becoming a more popular choice for homeowners. They have many benefits over traditional tank-style water heaters, such as taking up less space and using less energy. The most important decision you’ll make when installing a tankless water heater is what size breaker to use.
The National Electrical Code (NEC) requires that a circuit breaker be no greater than 125% of the rated load of the equipment it protects. If you have a 15 amp tankless water heater, your circuit breaker should not be any higher than 18 amps. If you attempt to put too much load on a circuit breaker, it will trip and shut off power to the entire system.
