Shared hot water heaters

[Terence Purcell]

I'm looking for more efficient solutions for shared hot water heaters in a multi-family property. I currently have 3 x 50 gallon tank heaters shared among 6 units - and I pay for water and electricity for the hot water heaters.

I've recently been investigating tankless due to lower operating cost - but they have a higher upfront cost - and feedback from plumber is that cold winters (here in the midwest) can result in them struggling to keep up when the temperature drops below freezing. Hybrid water heaters seem like a viable option to lower the monthly utility costs. They seem like they don't run out of water so quickly either.

Has anyone successfully replaced regular tank water heaters with either tankless or hybrid water heaters successfully?

Thanks in advance.

Your going to laugh. I own a 10 unit in Buffalo for the past 5.5 years and I have the same 60 gallon hot water thank that is shared with 6-8 occupants. They are all studio single occupants. I have $1000 sitting in the bank waiting for it to fail
