I bought a new condo as an investment property and the whole complex is having HVAC issues, cheap non pro install. Anyway, I've never seen this setup before an would be interested in your thoughts. The mechanical closet for my unit has a tankless hot water heater connected to a heater coil in the air handler, I guess much like an AC coil but for hot water. What do you think of this setup? My knee jerk reaction is that that the tankless heater will be running almost 24/7 during the heating season and didnt think they were designed for that tyoe of use.
Any thoughts on this system?
