Hey don't say that!!
I might of landed a job putting in a HUGE Rinnai tankless.
Guy just bought the house, has 8 people living in the house. 5 kids and 3 adults.
No chance for any water heater supplying that demand.
Told him to go with an oversized tankless for his needs and only because he wants tankless.
But when I told him that it'll cost as much as the heater to install it, he pulled back.
And when I told him that the sections of stainless steel piping near $100 a 4 foot section, he sat down.
Then I told him that he needs to clean the compartment regularly for hard water, he took medicine.
When I finally told him that no one in the area works on them and that hot water would take days, not hours to accomplish, he passed out and fell out of the chair.
In all seriousness though I told him that he would be one of the better candidates for the application figuring the requirements of so many back to back showers. Two water heaters I don't believe would work given the confined space the area allows.
I'd kill to have his tax status though; government probably pays him to have created all those social security numbers!!!
