Reznor Udap-350 Power Vented Gas Fired Unit Heater - Ng - 316 Stainless Steel Heat Exchanger - 350,000 Btu Review Sep 13, 2016

I have owned this same 400k btu unit for 8 years and it is the best purchase that I have ever made. It is used in a commercial setting and has never had a problem or service call. Reznor quality is second to none and definitely worth the extra cost.

Nice Panel Radiator Oct 16, 2016

I just wish it was more simple to figure out which connectors were needed. The description should be simpler. All I wanted was 1/2" copper connections but somehow the unit showed up with PEX connections. Overall good radiator though.

It's really helps a lot with one heater in a large room. Very Happy n Love it! Thank Runtal!

Good Unit, No Problems Aug 06, 2016

Used this unit with a 12, 18, 9, 9 set up with a 4-way distribution box, it has worked very well with very little noise. There is a very high pitched sound you can hear if you are near it, but it is not very noticeable.

Excellent Product Jul 27, 2016

Have had it up and running for about 4 days now, and have had no complaints. Using this for the main source of heat in a single wide trailer in the state of Maine. Got this for my sister and she called me last nite, temp was in the 20's outside and inside was 75 degrees, warmest she has ever had it in the cold weather since she has lived there for 30 years. Even one of her cats is not sleeping with them now, she is sleeping in the cat toy next to the furnace.
