I used autocorrect and I did not notice the error. I was in the plumbing section of the DIY forum but my reply ended up here. Oh well, no harm done. I truly love my tankless water heater and I would not go back.

The only thing I see is that they are running the same software and my reply wanted me to log on.

I think you have to calculate the heat, it might require a big enclosure with venting or even air condition enclosure. Which rating standard are you using? NEMA rating or IP standard? I found this site might be valuable if you looking for NEMA electrical enclosures. They provide many types and design including addon features like hinges, couplings, wheels, air condition, and many more. My company did order from them recently and everything worked out fine. https://www.nemaco.com, to study for type and protection recommend study from https://www.nema.org/pages/default.aspx and https://www.nema.org/Products/Documents/nema-enclosure-types.pdf
