Question by sean s: what size tankless water heater would I need for a 10 unit apartment complex?
I hear these new tankless water heaters are much more efficient and affordable. But is there one large enough to supply hot water to 10 apartments? Which one?

I don’t have an answer for you but I think not I would get a hold of one or more or the manufactures. He will be asking questions which should be easy to answer if you have the prints for the building or other wise they may offer to send a representative out take a look and see what is required for the job to be accomplished. The cost factor may be cheaper to install more then one or even ten. They are great!

The whole purpose of tankless water heaters is to right size them. Ideally, it would be a small tankless heater per faucet but it’s often one per bathroom, one for the kitchen and one for the laundry hookups. It would defeat the efficiency to get a single tankless water heater for a 10 unit apartment complex but it may be conceivable to have one per apartment.
Consider a solar thermal water heater if you do want a single unit for the entire complex, perhaps with a gas powered tankless water heater per apartment. The vacuum tube solar collectors can get the water to temperatures above boiling even on a cloudy day. With vacuum tube collectors, the water would get hot enough to run lithium bromide absorption chillers to provide for air conditioning and ten units would be just right for the smallest such unit (absorption chillers are typically large capacity for large campuses requiring hundreds of tons of cooling but 30 ton units are available)
The flats in Asian countries typically had one gas tankless water heater per apartment mounted out on the balcony which often doubled as an extension to the kitchen, you could often see the flare of the flames in the apartments across the street. I’ve noticed that the older apartment flats in Brazil had a similar gas powered tankless water heater in the bathroom tied into a central flue shared by many apartments (the flue shared not the tankless water heater), the ones that I saw were in disrepair, replaced with regular water heater tanks but it must’ve been quite disconcerting to have that flame flare up within the bathroom itself (those older tankless water heater had a window cutout so you could see the flame). Of course, the ones marketed in the states are much more subtle and inconspicuous and are often a sealed gray box rather than something that looked like a flame throwing jetpack for the Autobots.
