Can a tankless water heater be installed in my condominium?
I've heard mixed answers about whether or not a tankless water heater can be installed in a condominium, where there isn't a direct external "vent" to the roof. Though the unit does have HVAC with condenser on roof, and the dryer vent most certainly externally vents. There is an external vent in the mechanical closet. Can tankless water heaters be installed in condominium units, and if so, what are the limitations and requirements?

Yes you can. However every condominium association has its owns rules and regulations.

A tankless water heater can certainly be installed in a condominium - similar to any other structure. The easiest model is one that mounts externally - typically near the highest use of hot water or midway between multiple usage points. If there is some distance between the use locations, you can also install a D'mand pump to "call" the hot water so you are not wasting water waiting for the hot water to arrive. If you install a unit on the interior of your unit, e.g., in the previous water heater closet, the unit will require venting.  And - FYI - one reason people love to install an on-demand is that you can actually repurpose a former water heater closet creating more useable space in your condo.   One last piece of important information, you will need to check the size of your incoming water line.  Typically water lines are 3/4 inches in diameter.  On-demand units require incoming water lines of one inch.  So you may need to upgrade your plumbing to accomodate the increased size of your incoming water lines.  I hope that helps.
