DR. INFRARED HEATER Dr966 240-Volt Hardwired Shop Garage Commercial, 3000-Watt/6000-Watt

Installed into a 650 Sqft, 3-bay Insulated garage. Unless its below -20 degrees Celsius, it does a fine job of warming up garage to work in or melt snow off the cars. If you have steel garage doors that are not insulated, you should at a minimum start there with 4'x8' sheets of foil-backed styrofoam insulation that you can cut into pieces to snap into the door sectionals and tape the seams. Throwing up fiberglass bats between the wall studs is a very quick job. Drywall is an added bonus. This is an expensive unit to run, so you will make back what ever you spend on insulation. Highly recommended you use 10/2 or 8/2 armored cable to hard wire it. At 240v, you don't want to ever nick a a flexible dryer type plug cord. That voltage is enough to knock your balance off a ladder. I installed a mini 2-space breaker panel in the garage, wired to the main panel with 10/3 wire. (You should not bunch high current cables with other cables back to the main panel. Stove and Dryer runs are always given their own stud holes and space to avoid over heating). In the mini-breaker panel I plugged in a 15-30-30-15 quad breaker. The 30-30 is tied together for 240v and acts like a switch for the heater. Extra piece of mind, the heater has no power. The other two 15 breakers, I use for 2 additional 15a dedicated 120v outlets for tools. Obviously, I can't use them when the heater is in 6,000w mode, but they can be used at same time at 3,000w mode, or whenever the heater is off. The heater looks great and runs quiet, and the thermostat works accurately. I have left it on for 3 days at a time with no issues. You should run at 80% capacity for a 240v-30a (7,200w) circuit. And 6,000w is very close to that. As others have mentioned, you won't find a 35a breaker. Highly recommended purchase.

This heater is awesome. It performs very well. I have a 20x26 shop with 8 ft ceilings and shop is well insulated. I can warm the shop from the 30’s to the 50’s in an hour whic is well workable. I also have it positioned on where I’m working and periodically have to turn down the thermostat. I have it set at 6000 watts and don’t monkey with it. why would you. Let’s get some heat. There’s only one drawback with having it mounted from the ceiling because heat rises and your feet may be a little chilly but I’m only wearing sneakers. Wear an insulated shoe and you will be fine. I would definitely buy this heater again when it goes. It’s going on its 5th year of use with using it about twice or three times a week for about 4 hours each time. The price was good too. I recommend this product

Great heater, heats up a 2 car garage in minutes. Not super quiet but acceptable fan noise. Easily installed and works very well. Needs a 35 amp breaker and 8 guage wire.

So far, so good. Installed a day ago in my insulated garage. (an over-sized double garage) I had to run a separate line to my panel so I went with a 40A breaker - manufacturer recommended 35A but those don't exist. This is the first time heating the space and so far I'm really happy with the performance. It was 0 degrees C and went to 10 degrees C in less than an hour - so basically I can work in my garage with a t-shirt on cold days -- expect to wear a light jacket on really cold days like -20. Important - this thing does NOT have a power switch so I ran the power through a high current wall switch - also installed yesterday. It does power off if you rotate the knob all the way to the left so this was just me being particular. I don't plan on running it all the time and I really wanted to make sure I could easily kill the power to it when the garage was not in use. I found it odd the manual recommended switching it on and off by cutting the breaker --- circuit breakers are not meant to be used as a switch.

Internal fan motor broke, after 12 months and 1 week of age. It was used approximately 5 to 6 times maximum. The unit does provide great heat, and appears to be built with quality. Customer service was fantastic however.
