    Guidelines
    • must I use copper tubing in/out of water heater

      Guidelines
      • Thank you for contacting us 1kaz. You can use either copper or PVC, unless the temperatures you are reaching are above 180 degrees. In that case you would want to use the copper supplies. Please let us know if you have any further questions.

    • What size unit should I use for a 1 bathroom Studio apt with a maximum of 2 people.

      Guidelines
    • does this item come with all the necessary attachments? How do I know what size to get for my square footage? I have 1800 sq. foot.

      Guidelines
      • Hi, coolsesh1234. This water heater does come with a mounting kit. The right size for you would depend on the amount of water you use in your home rather than the square footage of your home. This product has a maximum flow rate of 5 GPM. Please let us know if you have any further questions. Thank you for your interest.
