Any commercial water heater is big dollars vrs residential. 2 -3/4" pipe size heaters piped reverse return have more pipe area than 1- 1" pipe size water heater tank style.
Two things to remember the flue size and gas line / meter size with larger or multiple heaters.Thanks for all the great responses. I do appreciate it. The Weil indirect thank I have is 80 gal I believe. Next step up is 120 gal and that is 7k for a tank. I reached out to armstrong for a recommendation on a recirculator system. i may try that. It'll be less than 1k to put in and I can go from there and see what is next. I'd hate to just drop the indirect and go directly to a tankless or tank, but I may if I have to. House was built in 2008. So it has whatever epa wanted from that time.
luckily this house has a 2" gas pipe and larger meter and flue size shouldn't be a constraint as i can direct vent out side of the house (about 6') so I have room.Two things to remember the flue size and gas line / meter size with larger or multiple heaters.
Similar but very different to the way we do them in Australia. Are most of your systems steel lined?you suggesting something like this?
