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.

Got 2 of these absolutely what was required. Very pleased. This is context. Very large community center in church basement (7200 sq. ' with 14 ' ceiling). Church has central heating, therefore obliged to heat entire building when community center was being used. These have allowed us to maintain 18 C in rest of church while raising the temperature to 22 C in community center. The 2 units will raise the temperature by 4 degrees in under an hour at 3000 Watts each and in about 25 minutes at 6000 Watts. So they are turned on via a timer before the event, raise temp to required level, also burns off the humidity. Golden age, Bridge Club etc. super happy. So what we are spending more on electricity which is more than offset by not having to turn up thermostat in the church section, which is 12,000 sq. ' with 90 ' ceiling. After 1 month we have seen electrical bill climb by about 2% but our gas bill has dropped by 7%. The net saving is about 500$. So given 2 units cost us about 1400$ installed that's about 3 month payback period. If you are not using this as a main heating system but as a supplementary point system, is a great solution. Especially in Québec ( -20 C today) with electricity at 6 cents KWh. this is a great solution. The ability to use (low 3000 Watt and high 6000 Watt is bonus as allows us to adjust for outside temperature. As a primary heating system who knows but to address our problem turned out great.

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.

I bought and installed this heater just before the Snow was predicted to hit Southern Alabama in 2025. It arrived well packaged from the manufacturer. Installed it in a 20x40 metal shop building, 10' walls. 3 inches closed cell spray foam in the ceiling and 2 inches in the walls. 3 double paned windows, 2 insulated man doors and a 16' x 8' insulated garage door. Admittedly, a little undersized, but I was hopping to avoid a big wiring expense, and it worked. I picked this heater for several reason, even though it was one of the more expensive models for its ratings. 1- 6000 watts vs 5000 for most of the under 30 amp draw heaters. 2- it came with a sturdy wall mounting bracket, I didn't have to make a ceiling mount. 3-I can add an external thermostat without having to add relays etc. That does require rewiring the supply line however. 4-No complaints of it being loud. It is noticeable when it comes on, but I can still hear the shop radio, and the heater is between my workbench and the speakers. 5- Good previous reviews. Bottom line- It works very well. It would heat the shop to 70 plus if I wanted it too. I turned it off in the evenings after I was done. The coldest overnight was 19 degrees outside, the shop was 49 inside. The day never got above 24 degrees. Turned on the heater, within an hour it was in the 60s inside and steadily warming up. I wired the heater to a flexible cable and ran it to a plug and outlet, In the picture of the heater, behind it is a little black box, that is the garage door opener, it has a thermometer built into it, and its temporarily mounted 8' up. The close up shows it at 76 degrees. The heater is mounted about 7' up. The round thermometer is in the coldest part of the shop, furthest from the heater, and it is 69 degrees or so and that is about 5' above the floor. At those settings, the heater ran about 35-40 minutes of every hour. I also ran a little battery powered Makita fan on low pointed up into the ceiling space to circulate the heated air up there back down, it made a noticeable difference. All in all, I'm pleased with the product and would recommend it.
