Ultra - 155,000 Sep 29, 2016

My suggestion is to have a very experienced high efficiency furnace plumber install the unit. From what I now know all aspects of the system need to be in balance to work properly. My unit is exceptional and my wife likes the colored pictures designating the various modes of operation.

Reznor Udap Series Oct 17, 2016

We purchased 75,000, 120,000, 150,000, and 200,000 BTU units, 28 units in total. The 83% efficient rating helped us offset the cost of the upgrade by being eligible for a rebate from our utility.

I'm so glad I didn't opt for air conditioning, saving a lot of $$.
