Does the Monterey wall heater work during power outages?

Hello, thank you for reaching out. Yes, the standard unit operates without electricity, ensuring heat is available when power is lost. If you install the blower accessory, the blower will not work as it requires electricity to do so. If you have additional questions, please feel free to reach out over the phone to our Customer Service line at 1-888-901-5460. Have a great rest of your day.
