About two years ago I purchased a 4unit apartment building in Houston.
Each unit has 1 bathroom and a kitchen, no dishwashers or w/d, each with
it's own water heater in the kitchen (a real eyesore). I'd like to
replace the conventional electric water heaters with tankless models to
conserve space and improve the appearance. Has anybody had any
experience with these units? I know that the current circuits will need
to be upgraded from 30amp to at least 50amp. Other than that, is the
installation pretty much plug-and-play? Is there any radiant heat
generated from the operation of the units? Do they make any noise while
operating?

Wow. About every other month, someone posts here thinking that this wonderful
new hot water system they dicovered called tankless is going to save them a
bunch of money every month. This is the first time someone actually has a good
reason!

State Industries has done a good whitepaper on tankless considerations,
including power requirements and installation.

I have a tankless water heater in my home and it works great! Have you
looked at the Seisco? You should try them out - they're a local
company. You can visit there website a www.seisco.com or call them.

The issue is not whether they work well or not. Assuming the tankless heater is
from a reputable manufacturer and is installed properly, it should work fine
under most conditions. There are some corner conditions (like very low flow)
where they may or may not work so well.
The issue is whether or not it is cheaper to use tankless over a storage tank.
While tankless can be less expensive to run in some situations, the overall cost
when you look at acquisition, installation, operation and replacement is at best
equal and in many cases more than would be for a storeage tank system.
That said, there are a few situations (like retrofit, vacation home, unusual
architecture) where you might be willing to pay the extra cost to solve a
specific problem.
