Installing 3 water heaters

[siklife]

Hi guys, how would you go about installing 3 75 gallon power vent water heaters (big house). The heaters will have a circulator pump and an expansion tank. Also, what kind of circulator pump would you recommend for this setup and expansion tank? Thanks for any help ahead of time!

hopefully you have the 3 heaters separated into 3 zones and are not trying to
tandem the things

The rough was done by another plumber. I’m guessing zones you mean each water heater for a different part of the house? If so that’s not the case.

draw a floor plan of the house, include the piping

is the house already sheet rocked?
is the piping looped under the slab, or is it piped over head?

the house is almost completely finished. One of the last steps is the water heaters. Im guessing the original plumber was going to do them tandem. 3 water heaters seems excessive but thats what the original plan was. The house has 3 kitchens, 6 or so bathrooms, 2 laundry's. Ive never installed 3 water heaters like this in a house so wanted some advice.

There is one pipe for inlet and one for outlet left by original plumber. These 3 will have to be installed parallel or in sequence. Im trying to figure out the best way to do it.

I’m not too familiar with the house and I can’t get into it to try and draw out a floor plan. Would it matter at this point since all that the plumber left was the inlet and return. Everything is looped above.

it would matter, if you can get to the water piping

and cut in return circ lines

if not just plumb the thing like the drawing i drew and fuk it it either works or it dont
holler back,
