Posted thread in wrong forum, so you Reznor owners are you happy with the heater? I have a Hot Dawg 60000 btu propane unit installed in my shop and it is louder than loud. Fan pushes the air good, no issues there, just unacceptable noise level. I see Reznor addressed this issue for the better so inquiring are you all happy about the noise issue generated by the fan. Thanks

Yes.
I installed a brand new Reznor heater in my garage in 2002. It's a 2.5 car garage in Minnesota and I keep it set right around 60 degrees for 5 or 6 months out of the year. I have had absolutely ZERO problems with that furnace. It has worked perfectly since the day it was installed roughly 22 years ago. I've never considered my garage heater as noisy. Sure I can hear the fan, but I can hear the fan on ANY hanging heater. It's no louder that is "should" be.

It's the only brand I have installed since 84 just replaced the first one I ever sold. They do cost a lot more than big box stuff.

I've made mention of this in multiple posts about how loud and annoying my Modine Hot Dawg 70k btu overhead gas heater was in my last shop. For the first 20 years in my old 34'x34'x14' shop I had a used Reznor 75k btu gas heater and loved it. About 4 years before selling our home I had a new furnace and A/C installed in the house and while I was at it, I had the gas heater in the shop replaced as it was getting old and I had already replaced a fan and gas valve and was worried about the combustion chamber rotting.
The contractor recommended a Modine Hot Dawn even though I had asked specifically for a replacement Reznor. I was very disappointed and had to live with that POS for the last four years we were at that home.
When I had my 50x60x16 shop built at our new home, I insisted that the contractor install a 150k btu Reznor and not to even talk to me about anything else. I couldn't be more pleased as this is our 6th winter in the shop and it is quiet as can be. All we use currently at work is Reznor as well.
I have been very happy with the air movement and heating provided by our Reznor 150k UDAP gas fired heater and especially how nice and quiet it is.
Thanks for replies, I'm so disgusted with Ecomfort.com , they had a million opportunity`s to say something about the noise this unit generates. Gave up trying to hear radio or if I do and heater shuts off, it's blaring. Modine in my opinion has a big design issue and seriously wouldn't recommend it for nothing. I also see now Reznor is using the quietness of there unit's as a big selling point. Not sure what outcome I'm going to have with this heater but have to come up with something.

Yeah, I learned the hard way. I will never recommend a Modine Hot Dawg to anyone, not even someone I don't like.
I have a 60k btu Reznor UDAS and it's been great. I don't have any problems with noise. Now, I also have a mitsubishi mini split heat pump so the propane fired Reznor doesn't run as much. It's great for quick heat up or for really cold days.

I have a Reznor and it had a terrible rattle. It was caused bu the front bracket that supports the heating coils. I had to wedge a thin piece of metal and used the red high temp adhesive on each shelf to stop the rattle. Unit is 5 years old, maybe they did a mod to stop it.

I've had both a 45k and then a 75k Hot Dawg
Both are fine in the "noise" department , not loud and not a concern

My first winter with a 40K Reznor. Very happy with it and don't mind the noise. I occasionally hear it go on or off, but mostly just fades into the background. I'd say it is roughly the same noise as the 100K units in the house - you hear them go on/off once in a while, but it is mostly background noise.
I keep my TV on YouTube in the garage, and I have noticed I have to bump it a couple notches on some channels with poorer audio quality.

How do you have it mounted?
I have had some success with hanging a heater with rubber mounts. Sometimes mounting right to the ceiling, or with threaded rod puts some stress in the cabinet and causes noise.
As far as which unit is quieter the votes are about 50/50!
I used to sell Reznor, then later sold Modine. IMO, Moline is a better unit.
I used 3/8 all thread attached to trusses and then incorporated 1 5/8" unistrut braces. Its not going anywhere, now considering reducing the wire shroud around fan a little at a time. Beyond that maybe not such of a aggressive fan, not needing this unit to blow air to end zone. Building shop I installed ceiling fans to help move air, just a ridiculous amount of awaranted noise.
Thammel, how high is your ceiling. Thanks
You've had way more experience with these units than me but just a fyi I see Reznor is hooting there horn about quetness of operation.
Before I retired about three years ago I had adds showing that Modine was quieter than Reznor!
Figure's.

I deal with both brands weekly at least. Not once have I said, wow that is much quieter than brand B.
Other than the one occasionally rattling I have not been offended by the noise either. If you want quiet either go with mini splits or in floor heat.

I sold a Modine to a contractor and it was loud! We looked it over and didn't see anything for certain. I talked to him a few days later and he said he figured it out. He had it mounted close to the ceiling on 3/8ths threaded rod. He removed the rods and added four rubber hangers and it was quiet as a Reznor! 
Something about the mounting had the heater distorted the cabinet a bit and caused a rumble.

I have a Reznor 45k btu that I don’t think is overly loud. In fact it’s on right now 10ft over my head as I’m watching the Mecum auction and didn’t have to increase the volume on the tv at all. Now the 5 second rattle when it first fires is a different story.
twelve feet....

My buddy has the smaller version of the Hot Dawg, and it's pretty quiet. Different mounting methods can couple different amounts of noise to the structure. Additionally, it appears you have a new shop with bare walls/ceilings and presumably nothing in it. It's just going to be a huge echo chamber. It will probably sound a lot quieter with stuff in it.
Also,I really wouldn't put any blame on eComfort. They publish the full unit specs, and provide all of the factory documentation on the website. Loudness is objective, and it's not for them to say "Warning, this unit is loud!" on their site, especially since they never fired one up. If Modine doesn't give them the measured noise level, what are they supposed to do?

I had a 75K Hot Dawg natural gas unit installed this summer in my 2- 1/2 car garage.
I consider its noise level "normal" and certainly not excessive.
Though my noise perspective is comparing it to the 1953 80K Janitrol unit it replaced.
I have two ceiling hung heaters, one in attached three car garage and one obviously in shop. Two things I was trying to convey was finding a solution/ repair of loud heater and give future prospective buyers one of a gazian negative hands on experience' s with this unit. As for the seller I'm not sure how in good faith that these units would be in there inventory for sale. They certainly did me a big $$$ disservice. So big thanks to everyone for insight and help. Go Seahawks.

But are both spaces still empty, or are they full of things? Shelves, benches, vehicles, tools? The "things" inside a space absorb A LOT of noise. Even a very small noise in a big open room with nothing in it can sound very loud. You also need to keep in mind that these are "shop" heaters. They are never going to be as quiet as a residential furnace with a blower sitting in your basement.
Like I said before, ecomfort is just a retailer. They don't take every heater out of the box, hook it up and assess its "loudness" (which is completely subjective) before sale. The unit has good reviews on the site, and a few comments said it was quieter than their previous heater.

Shop is 60% full up to the 10' level + - . Retailer doesn't have to test them all, simply grab anyone of them, off the top of the pallet or the bottom . 99.9% Sure if there's a competent person there with reasonable hearing it's not going to be a green light. Theirs way to many negative post about this heater and there all the same ( LOUD fan NOISE ). So for a final closure, good luck fellow GARAGERS. AND HAPPY NEW YEAR.

You obviously have more experience selling them than I as an end user, however, from my experience having a Reznor in place for 20+ years and then replacing it in the exact same shop with the exact same size, I can say my experience is quite different. Even now with my 150 btu Reznor, I think the burner is almost louder than the fan and I can be recording video and don't have to stop when the heater comes on. The last shop I had to suspend any filming when the heater started until it kicked back off.
