ModineHD45AS0111Natural Gas Hot Dawg Garage Heater 45,000 BTU with 80-Percent Efficiency Grey

This heater works awesome !! I installed it myself in about 4 hours including cutting in a vent through the outside wall, but the gas line, power and thermostat wire were already roughed in from when I finished the garage in last summer, so I didn't have to run them while installing this heater. I had to use 1 1/2" slotted angle braces to hang it from the ceiling because I wanted it angled and mounted in the corner of my garage. The mounting holes in the heater's hanging brackets are not wide enough to mount it angled without putting additional blocking in the ceiling between standard 24" OC trusses, or using slotted angle braces like I did. I pulled a homeowner installation mechanical permit which added another $65.00 to the cost. I know a lot of people install them without a permit, but if something goes wrong and my garage burns down I don't want my insurance company to have ANY reason to try and get out of taking care of it. $65 is cheap peace of mind in my book and working with the inspector was very easy. I used 3" double wall B vent pipe and fittings sourced locally which are easy to work with and attach to this heater. I do think it's time for Modine to replace the ugly green/ grey color in favor of a more modern/ pleasing one like white, black or silver. They make a limited edition one that is black but it costs a lot more and I couldn't find it on Amazon. This thing looks like it was coated in prison colors lol !! I have a nice bright finished 3 car garage and this thing heats it up fast !! It just looks ugly. I am taking mine apart this spring once I don't need it anymore and having it powder coated white. The inspector and I both like its compact size and quiet operation. I used an Emersen UP310 programmable thermostat also from Amazon which works great and adds a fan only function which is nice if you want to circulate air without the heat on. I mounted the thermostat on a short partition wall shielded from the heaters air flow 12' away. It works great and keeps the heater from short cycling. My garage is properly insulated and drywalled and this heater can handle our Northern Idaho winter with ease, taking it from low 30's to low 60's in the garage in 15 to 20 minutes !! Once warmed up, it runs once an hour or so to keep the temp where I set it. What a difference !! Other than the cosmetics, this thing is great and I highly recommend it !! I only wish I had bought one sooner !!

I had a gas line ran around the side of my house to the back of the garage. Originally, I tried a non-venting wall hanging gas heater. NOPE! TOO MANY FUMES. Regardless of what I heard people saying . It will be fine. Just crack a window open won't be a problem. This Bodine Hot Dawg heater is the cats meow! I mounted it to the ceiling and had an installer hook it up the gas that is. I did the venting thru the wall and out just passed the overhang. Only purchasing the vent pipe and a thermostat, those were the only extras. You just can't take the cheap route. This heater is worth every penny I spent!

I installed this in the fall and it has been wonderful all winter! It's high-quality and reliable, and kept my garage above freezing all winter, even at -15 outdoor temp. I have a detached garage (AKA "the man-cave") and this year has been much more enjoyable to work in a "sweatshirt" environment instead of heavy coveralls. It's efficient and cost less to operate than propane tanks for the space-heater I used before. It's terrific not worrying about open flames like I had with the glow-heaters in the garage. In the future it will be a "value-added" feature for selling the house, "heated garage." I'm extremely happy with it.

Installed about 3 months ago.It is working nicely and keeps my 2 1/2 car freestanding garage warm. I have 6 inch insulated walls. Ran 1/2 inch CSST gas line and connected heater to Honeywell programmable thermostat. No issues with installation. Used double wall stainless steel venting through the wall with a thimble which was fairly expensive (about $100). I have a 400 sq. ft. apartment above the garage and am able to heat it with just a small space heater. This morning was -12 degrees in northern Indiana and heater is doing its job. I keep the temp at 55 degrees and turn up to 60 when working in the garage. It takes about 10 - 15 minutes to increase from 55 to 60.

I mounted this in my garage nearly two months ago and just now got the gas line run to it. This heater raised the temp in my garage from 42 degrees to 65 degrees in about fifteen minutes. I have a two and a half car garage, about 90% insulated. I have no doubt this heater will do fine, even in the coldest of weather here in Ohio. Mounting it to the rafters (alone) was very tricky, and wiring the new programmable thermostat was a bit confusing, but all is good now. This is something I should have done five years ago when I built the garage, instead of using VERY expensive electric heaters. Oh yeah, it,'s very quite too. No rattles or loud noises. NICE!

Got us through our first winter in Colorado without a glitch. Set it up in our garage gym. 15-20 mins running and the garage is ready

works better than expected. Its only 80% so 20% of your heating costs go out the chimney is all. I knew that before I purchased it.Also, I converted it from NG to LP and that went very well. It does what they say, so I am impressed.

We wore the old modine furnace out after only 25 years. Found out the btus it used to have and started looking. We found some a little easier to buy. However the reviews made those seem like trouble. Living in the sticks dependability means something. We ordered from Amazon and they said okay. This was the most expensive purchase and the heaviest we have ever done with them. The debit card was billed when they shipped. Prime is a good deal. Ordered a thermostat. When it all arrived it arrived on time and in good shape. My Elder Son and my Son in law had it up. in short order. Only three trips to town for parts. Lag bolts and 4inch to 3 inch conversion to tie in to the existing flue and a few feet of new pipe. A roll of wire for the thermostat. The wife and Daughter made barbeque. Took 15 minutes to cook off the factory coating. Its been so hot here it then sat there for over a week before it came on again. It is quieter than the old one. My Grandson thinks the box it came in is a lot of fun. We will feel safe at night and will be warm in the woodshop. Thanks everybody!

Had it installed by a licenced fitter. Heats a 24 x 24 shop with no issues. Runs well and heats quickly. Fan is a bit loud but not annoyingly loud.

FANTASTIC HEATER......I INSTALLED THIS OVER THE SUMMER IN PREPARATION TO THE COLD WINTER MONTHS AHEAD. AFTER DRYWALLING AND INSULATING MY GARAGE THIS YEAR , I COULDN'T BE HAPPIER ON HOW THIS UNIT KEEPS MY "MAN CAVE" Nice N Warm IN THE FREEZING COLD TEMPERATURES FOUND IN MY REGION. VERY REASONABLE TO OPERATE....FARILY QUIET TOO

What a great product. Look forward to trying it on this winter. Only thing used was the box

It,s exactly the gas furnace I needed,, easy to install, and great performance,,now,I,m ready for winter..

Just tried it and it looks great on the heat production. Hope it will work well thru the winter .
