Do Tankless Water Heaters Require a Dedicated Electrical Circuit?
Whether or not a tankless water heater requires a dedicated electrical circuit depends on the size and type of unit.
Electric tankless water heaters typically require a dedicated circuit, while gas tankless water heaters do not.
Electric tankless water heaters can draw a significant amount of power, especially when they are first heating up.
This can put a strain on your home’s electrical system and could even cause a power outage.
To prevent this, it is important to have a dedicated circuit installed for your electric tankless water heater.
Gas tankless water heaters, on the other hand, do not require a dedicated circuit.
They use very little electricity to operate, typically only enough to power the controls and ignition system.
You can safely plug a gas tankless water heater into a standard outlet.
However, there are some exceptions to this rule.
If you are installing a gas tankless in an area with a high electrical load, such as a bathroom with two showers running simultaneously, you may need to install a dedicated circuit.
This is to ensure that the water heater has enough power to operate properly.
If you are unsure whether or not your tankless requires a dedicated circuit it is always best to consult with a qualified electrician.
They can assess your home’s electrical system and make sure that your water heater is properly installed.
Here are some tips for choosing the right electrical circuit for your tankless:
- Make sure that the circuit is rated for the amperage requirements of your water heater. You can find this information in the water heater’s owner’s manual.
- Use a circuit that is dedicated to your water heater. This means that there are no other appliances or devices plugged into the same circuit.
- Use a circuit that is protected by a ground fault circuit interrupter (GFCI) outlet. This will help to prevent electrical shock.
By following these tips, you can ensure that your tankless water heater is safely and properly installed.
