Every tankless I’ve used has been a piece of crap. Constantly breaking down. Heat surging and going cold in the shower. Outright just not heating water. All within 2 years of install. Never again. Tanks only for me from now on.
I ended up getting 2 hot water tanks and putting them in series. Endless hot water doing it that way. I’ve also plumbed it so that if one fails I can adjust a few valves and run on one tank until I can fix/replace the other.
I should note, I live 160km from the nearest city so I can’t just call a guy out to fix things.
I talked to a plumber and it’s what he recommended. I decided to not to question someone with far more experience than me. Your solution would probably work too.
