Hello. I have recently received 2 quoted to have installed a unit heater for the garage. I am looking at the Reznor UDAS or the Lennox HotShot (sealed combustion). They were both quoted at roughly the same price. My question for the pros (and I hope it does not contravene any of the rules) Are there any strengths or weaknesses with either of these units? They appear the same on paper, but is one likely to outlast the other/provide better service?
Not looking for a "this one is better" but maybe an opinion from someone who has installed both in their carreer. Thanks in advance.
