That may, or may not, work. Depending on the rules and codes. If it’s required after a certain date, and you’re not able to install it yourself, then you’ll have to hire a contractor, who will have to pull permits (yeah, I know, cash is king). Those permits will necessitate inspections, and they may not like your old-style water heater being installed after the cut-off date.
First it as the more efficient toilets that need to be flushed a half dozen times then it was the washing machines that use water savers and leave suds and powder stains all over your clothes, they both suck and so do the idiots that are passing laws and force us to purchase this crap
Hmmmm, not a bad idea !
The codes intertwine.
If you don’t need it, don’t replace it.
When the energy efficiencies are calculated, tankless will probably prevail, especially if you have 3 phase power available.
