Everything you probably want to know about the DR-966
The heater requires a 35A circuit with #8AWG wire per Article 424 of the National Electric Code. The heater only pulls 25A on highest setting, but is considered a "fixed" device with a "continuous load", so the wiring and breaker need to be rated at 125%. That puts it at 31.25A, over a #10AWG wire and 30A breaker's rating. Don't risk your insurance company denying your claim if something goes wrong. At that power, you don't want to use a line voltage thermostat designed for smaller baseboard heaters. If you want a wall mounted thermostat, look into any conventional thermostat, a 24VAC HVAC transformer, and a 40A 2-pole 24V HVAC contactor. I have three DR-966 heaters with their built-in thermostats all the way up and their switches on the 6000W setting, running off a single 24V transformer and Hunter 429999B thermostat, with a contactor near each heater switching the 240V AC on and off. If I'm not in the building I keep the thermostat at its minimum 45 degrees setting to prevent pipes from freezing. Using a contactor, you're essentially automating turning the heater on and off, no different than using the instruction manual's method of using the circuit breaker, and not voiding any warranty. This is not an infrared heater, the manufacturer calls itself both Dr. Heater and Dr. Infrared Heater. The heater is a wire coil type, the front two coils are 1500 watts each tied together, the rear coil is a single 3000 watt for a total of 6000 watts. With the fan blowing on them, a spiral or two of the rear coil may get red, primarily near the coil supports. If the fan doesn't turn the coil will get red hot, and probably break the support wire inside and then droop. I received one heater that had a bent fan bracket not allowing the blade to turn and when powered up the rear coil did just that. I received a refund to buy a third heater and since the vendor was filing a damage claim, was told to discard the defective heater if after 10 days the shipping carrier didn't contact me to inspect it. After the 10 days passed without being contacted, I straightened the bracket out, verified the fan worked and then adjusted the drooping rear coil so there was a minimum of red spots. I ended up with 3 heaters for the price of 2. Although the output of the heaters may feel like no more than a hand held hair dryer when your area is cold, follow the instruction manual's recommendations of keeping it the proper distances from walls and other objects. If you feel it isn't putting out like it should, use a clamp-on ammeter to verify the heater is drawing around 25A on each leg with the temperature control fully clockwise and the switch on 6000W. If it's not, contact the vendor. I have a 30x50 pole barn shop with a 10' ceiling, so the roof peak is about 12'. It has "double bubble foil" insulation on the walls and roof, with exposed trusses. The heater's manual recommends 1.25 watts of heating per cubic foot, so 30' x 50' x 11' x 1.25W = 20,625 watts. With 18,000W of heaters, I can set the thermostat at 60, go to the home store 10 miles away and by the time I get back the heaters have shut off. If I already have my materials and I'm in a hurry to get started, I supplement the electrics with a 3-burner 45,000 BTU tank-mounted propane heater to raise the temp to 60 faster. So a single 6000W heater in an uninsulated 3-car garage may not be adequate. Before I contacted the eBay vendor about the damaged heater, I contacted the Dr. Heater by phone. They told me they would send a replacement heater and pre-paid shipping label. Then I received an email stating they would email me a label within one business day and start the replacement process. I never received the label by email. When I called Dr. Heater on the second business day they said they would email a label by the end of the day. I never got that, so I resolved the issue with the eBay vendor, a 10 star solution. So it may not be worth the stamp to send in your warranty card. If you get a working unit, it's worth the money. Good luck repairing one later, since parts don't seem to be available. Due to one of mine having a bent fan bracket, if you get a DR-966 in the 160014xx serial number range, stick a screwdriver in the back and try to spin the fan blade before installation. A pallet of these might have gotten dropped on the dock after coming off a ship from China. If that bracket was bent before the heater was assembled, then don't trust the QC sticker on the back. It hasn't got to zero outside yet, and I haven't got my first electric bill, so I may be in for a shock in that respect.Verified purchase: YesCondition: New

DR Heater DR966 240v Garage Workshop Infrared Industrial Space Heater
It's an OK heater. You MUST user the heavy 8 gauge wire and the 35 amp circuit breakers that the instructions say. It has a much quieter fan than my old one, so that's a really nice thing. Puts out a good amount of heat for a small heater. So Great so far? The only bad thing that I have to say about it, is the same as a couple other reviews. The thermostat just doesn't work right. It turns on at 65 degrees and cycles on and off like you would expect. But during the day it keeps turning on more and more warming up the shop by turning on at higher and higher temps. By the end of the day it was turning on at 79 degrees and this was with the thermostat not being moved, set the same all day long. So if it had a better thermostat it would easily be a 5 Star heater. Better yet a remote mounted thermostat would be Great! Heats up my well insulated shop 20X16X8 even when it dropped to zero outside. So it's a GREAT heater with a crappy thermostat.Verified purchase: YesCondition: Pre-owned

Good heat great price
Installed this heater on a 20 degree day in a dairy milk house ( block building). It had that space up 65 degrees in 20 minutes.This was at the full 6000 watts. Then left the thermostat at 3/4. This was adequate for me. Maybe 70 degrees at full power? A really quality unit for price!Verified purchase: YesCondition: New

Mr Heater
1000 square foot shop stays warm when it’s 30 degrees outside. I keep the temp about 58 to 60 when working. Any warmer and it’s not comfortable. Fairly quite on high. Great value on a heater. Propane was costly and dangerous in a shop using flammable liquids.Verified purchase: YesCondition: Pre-owned

Great deal.
I got this as an open box, but looks brand new. Got it for a great price. I have it on a 30 amp breaker with #10 wire. Seems to work very well with no issues.Verified purchase: YesCondition: Pre-owned

Very satisfied with this heater. I would purchase another one if needed.
This is a well built product at a reasonable price. It is easy to install. It cycles properly and maintains the temperature in my 24'X24' garage. I was expecting more fan noise but it is fairly quiet.Verified purchase: YesCondition: Pre-owned

Good replacement for for my old Comfort Zone heater.
Does a good job heating my garage/wood shop. Some mentioned a need to upgrade the electrical capacity. I have a 30 amp breaker with #10 gauge wire. Recommendations are 8 gauge with a 35 amp breaker. I decided to check the amp load of the heater before upgrading. I wired it up and put my clamp meter on both legs at high power. Reading was 21-22 amps per leg. 10 gauge wire is rated for 30 amps. I now run the heater on low when not present in the shop. I switch to high only when I’m in the shop if necessary. No problems at all. Puts out the heat when I need it. Anyway, I do plan on upgrading wiring and breaker when the weather warms up. Good heater, good price.Verified purchase: YesCondition: Pre-owned
