Review Title: Garage Heater
Comments: I have just completed installation of my new heater in my three car garage. The process was simple and easy since I had previously wired the garage with 220. The heater works fine,but it has not really been cold enough yet to thoroughly test its ability to heat the garage. I look forward to the first really cold day so I can test its capabilities.

Review Title: NewAir g73 Garage Heater
Comments: Okay first read all the reviews. They were all good. So ordered two for my detached two car garage, which isn't fully insulated. Plan is to be able to work restoring my 65 Stang during the winter and want to be able to turn heater on for bit before going out to work. Temp the other morning was 33 turned them on for a bit went back inside to finish my coffee. Came back later and it was nice. These will work as planned. Not loud, easy wiring (used dryer cord) quality in workmanship and design. Well worth it. When I expand my garage will purchase again.

Review Title: G73
Comments: Delivered quickly, packaged really good, surprised how small heater was, hooked up easily with 30 amp breaker and 10-2 wire. Hooked heater up, didn't smell on start up and relatively quiet fan, puts out plenty of heat, have to keep it on lower setting. Might buy another for other garage.

Review Title: G73 Heater
Comments: Product arrived in good condition. The box was a little beat up from shipping, but the heater did not seem to take any damage. Installation instructions were good. I would like to see the instructions cover the usage of 10-3 wire in addition to the 10-2 that is listed. Wiring was easy (after I figure out how to use the 10-3). Installation was easy as well. My garage has been staying at a comfortable 50 degrees since installation. Having heat in my garage has basically added another room for me to use, especially in the winter months. I would recommend this heater to anyone that asks.

Review Title: Love It!
Comments: I looked around for some time before I decided to get the G73. Wow! What a great heater in a small package. My shop is not even insulated yet and it has brought the temp up 10 or more degree's in about and hour.

Review Title: Nifty!
Comments: This is one nifty solution for when you need to work in the garage in winter. I've got a 750 Sq.Ft. garage and at the 4kw/14,000 BTU setting it will hold a 60 degree temp when the ambient is 20. The flexibility to adjust its output depending on available circuit capacity is a nice feature. I have a 20amp circuit to the garage which is just a tad shy of what I need for the full 5KW output of this unit. So, just move a jumper to set the output to 4kw/17.6A and I was in business! I'll pull a 30amp circuit this summer to take advantage of the full 5KW/17,000btu capacity

Review Title: G73 Garage Heater
Comments: I live in the north east-Long Island, NY and purchased this heater to heat my 2 car insulated garage, which is attached to my house and is approximately 425 sq. ft. The product was delivered in a timely manner and arrived in tact. I followed the installation and mounting instructions that were included. As a do-it-youselfer I directly wired the heater into a subpanel in the garage. My biggest disappointment is that it doesn't heat the garage very well, especially on very cold days. It has to run hours to get some slight warming. It seems "undersized" to do an acceptable job in this size space. The heater works fine BUT I would only recommend it for a much smaller space.

Review Title: Great heater
Comments: I've owned this for about a year now, and I'm telling you, this is a great little heater! I have a 2 1/2 car garage (not insulated but dry walled) 600 sq. ft. mounted on the ceiling, and this heater is more than enough to heat it! (Midwest winters) The only drawback is the thermostat. I took it off and mounted it on the wall so you can reach it. #12 wire and conduit, and a box, and you have it.

Review Title: good service
Comments: I ordered the G73 unit after researching a bit on the net. I got a good price (10% off on the day I ordered) and shipping was quick and easy. I installed the unit with a separate circuit and line and it works nicely. It is quiet and heats my shop well. I like the "moments notice" heat. It's there when I want it to be and if I choose to run it for days at a time, it's up for that too.

Review Title: Good Little Unit, G73 Garage Heater
Comments: We installed this in a 13' W X 25' L X 9' H insulated garage. It easily raises the temperature 20 degrees F, on the low setting. The thermostat allows us to adjust this for warmer temperatures when we're working in the garage. It is a very quiet heater.

Review Title: Heater reveiw
Comments: I was very happy with the great price and timely fashion it arrived. The free shipping was a huge deal too. However, I was a little disappointed with the heat that the heater produced. I guess I was thinking toaster oven. Or even home depot electric heater.(they get pretty hot)..But any way. The biggest complaint was that the motor in the unit vibrated so bad, it made the heater extremely noisy. I had to remedy that by stuffing a folded piece of foam between the back of the fan and the grill. That absorbed the vibration and made the unit very quiet.(I think the fan blade is not balanced) But you don't figure that all out until it is wired and mounted. Hope this was helpful. Jim

Review Title: G73 Garage Heater
Comments: When the Weather was 17 degrees I purchased the G73 For my 2 car size garage workshop. Hung it by the single 3/8 bolt to swivel it and made sure it was centered in the joist. (the shield cable I used doesn't allow it to swivel. I may change to one more flexible.) The first time I turned it on the pause feature threw me, thought I had no power, but it came on as the instructions said and has worked beautiful ever since On the low setting my shop is warm enough for a light jacket. Will see what it does to the electric bill when it come in. Would do it again if I need another.

Comments: It is 19 degrees this winter here in NJ, and although our garage is insulated, it seems just about as cold in there. I was refinishing some antiques, and was really tired of trying to do it in a coat and gloves. So it was off to Lowes to buy a heater. I one I got was woefully inadequate, so I went online and found yours. It arrived in about a week. A quick call to my electrician and the next day he had it installed in about an hour. The heat is perfect for our 600 sq. ft. garage. Thanks.
