Ultra - 155,000 Sep 30, 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.

Easy Install Apr 15, 2016

Using in warehouse to prevent pipes from freezing, but since the weather hasn't been very cold it is difficult to evaluate. The install was fairly easy.

Reznor Udap Series Aug 12, 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. All heaters were installed and work beautifully. The heaters look great! They are installed in a warehouse with great WIFI access so we controlled all 28 individual heat zones using 28 WIFI thermostats from Honeywell. Couldn't be a happier customer!

Way Too Slow...using Too Much Water Nov 17, 2016

I installed the heater per the installation instructions...upgrading my natural gas line to 3/4" from the meter to the heater.

Any savings I may have gained from doing away with the pilot lite and storage tank will be more than lost letting the water run for 2 to 3 times longer than with a tanked water heater.

Great Service And Great Product! Apr 15, 2016

I ordered the Modine unit from this site. After i placed the order I received a call from a customer rep to verify the order details. I realized then that I did not ask for lift gate on shipping. The rep added that for me. I received the unit within three days and it installed quickly. It works great!
