        Q:Your documentation says "Do not connect to a GFCI or AFCI circuit." 2023 NEC electric code requires GFI on outside outlets. How do you address this conflict? Thanks

        Answer This Question

        A:  Hi Dmrfo and thank you for your question. You can install on a GFI if required, just note there maybe nuisance GFI trips. It will not hurt the water heater.

          I bought and installed my own.
          Three years in, and not a glitch. I think I oversized mine because looking to sell and not knowing future home owner's needs. Just like air conditioners, don't oversize just because. heater performs better when allowed to run wide open. Don't store hot water! Makes no sense.

            A great, easy to install hot water heater
            It was simple to install right outside the bathroom wall to have hot water available in only 20 seconds. It does make lots of strange clunking noises when the water is turned on and off which I hope is normal. This should also use less natural gas than the tank hot water heater located in the garage, a long distance from house fixtures

            i had this water heater professionally installed, been using for about 3 weeks. I think it's taking a longer time to heat up water than I anticipated and I live in Orange County, CA, which outside temperature is around 50 degrees at night and around 70 in the day during winter time. I'd expect it to heat up faster for such an expensive unit.

            This unit seems to work fine. It is to bad I had to wait a week for it to be delivered instead of picking it up at the store.
