Default 75 gallon tank vs. Tankless

Calculated demand and a house im working on needs over 12.5 gpm tankless. Which apparently means two tankless units. He currently has a 75 gallon water heater. How does a tankless with 8gpm compare to a 75 gallon tank unit? Cant find anything really online far as a chart may be concerned.

I'd call a manufacturer they would know what to recommend.

its mostly going to boil down to cost.....

unless the fool wants endless hot water in the shower
where he can stand there all day long...... the 75 gal power vent
is what I would prefer having ...


I am having this debate right now with a customer ....

I have never met an unhappy tankless water heater customer. All positive reviews and feedback. I mean performance not defects or installation issues.

What about a jetted/soaking tub? 75 might not be enough. A new customer of mine has a 4 person sized jetted tub and it's used (according to him) sometimes twice a day.

He currently has 10-15 guests at his house for Easter weekend. Extremes? Yes, but a few dollars more and you have the extremes covered. We probably install 20+ tankless a year.

I'd go tankless in that range. Get a Navien 240A, get two of them if needed. 75 have gone up so much, in that range tankless makes since imo. Rheem also makes a good tankless(Paloma)

I only install takagi tankless heaters, so far no issues, but that doesnt mean they will change design in the future, I try to stick with 1 manufacture until systemic problems occur ...and you have to look at performance and the luxury side ( unlimited hot water) before you worry about price...the guy buying a Lamborghini doesnt shop by price, he shops for performance first, thats what a tankless is..a performance heater...

After reading all these posts you guys all get free gas licences??? Or you did a plumbing contractor licence and another separate contractor exam for gas? What about insurance for gas? One of my boss told us it cost him 8 000$ a year for gas insurance.
