I've seen one at an HVAC show, it's not unlike most condensing furnaces. 93% efficiency has a draft inducer and appears to use PVC exhaust. One thing about a condensing unit is that you need to plumb both an intake and exhaust piping.
Am I right in understanding if you use this type furnace as an occassional turn on unit, rather than w/ a thermostat that there will be freezing issues if it's used in sub freezing weather?
