Review: received today - so tentatively, it's doing well at the moment (more in review text below) - I have a new 35' x 50' x 18' "minimally insulated" RV garage/workshop (with a 3rd floor 8' attic) - I ordered the heater a few days ago and it arrived very fast. (ahead of time I had been told) notes: - heater was started with garage temp at 52 degrees F - outside temp dropped today to 29 degrees F - heater has been able to gain 2 degrees F to 54 F on the first level in this huge space (I'm more than a little surprised at this) - heat output seems unimpressive in my opinion standing at the unit, but the results (again so far) on my first day of use, far exceeds my expectations - the thermostat likely will have to be replaced with something with a better "differential," but for the moment I'll just set it a bit higher. - To connect it to a 50A welder outlet, I ordered a 6-50P to 6-30R adapter cable from desertcart, which, as expected, worked perfectly (https://www.desertcart.com/gp/product/B07P6THGKJ/ref=ppx_yo_dt_b_asin_title_o07_s01?ie=UTF8&psc=1) - so my only (minor) negative is the stock thermostat differential - the unit is adequately quiet - this units fan is "balanced" and no vibration - the unit came very adequately packed and double boxed - this is a big building... All I was expecting was to be able to maintain something above freezing so I wouldn't have to winterize the RV. I am shocked this heater alone, seems to be gaining temp - I will be installing a heat pump for this building, but for now, I'm pretty much surprised this single heater has maintained or slightly gained temperature. - at the time I took the attached pictures, the outside temp was 29 degrees F (attic temp was 48 degrees F-1st level temp was 54 degrees F) - bldg insulation is 1-2" of spray foam (closed cell) in attic and walls are 2" rockwool) on edit 2/18/2021 - well this heater didn't gain on 12 degree days, but it held the temp at 45 (and still cycled) - at 23 degrees it's able to gain (set at about 45 degrees) - it is probably the most expensive way to heat the garage, but I only need it to keep the temperature above freezing - so it doesn't run all the time, it cycles - I remain satisfied - I won't be trying to reach 50's and 60"s - I think that may be a little rich - I just want it to keep paints and the RV I have stored in there above freezing and it's doing that easily - I haven't had any problem with the unit so far - I know some say they had issues, but it seems decently well built and I basically like the unit very much, again, so far... I'll update if that changes, but I have no reason to expect a change edit 3/12/22 - changed my mind and my review to 5 stars - this heater has just worked too well for me - I can hardly believe how well it's been working - very very satisfied edit 12/24/22 Yikes! 0 degrees F yesterday -20 degrees F wind chill 2 degrees this morning -6 degrees F wind chill The heater is running "flat out" and continously, BUT, at least on the 1st floor, it's 45 degrees F and NOT losing. 3rd floor is at 32 degrees. (dry storage floor) "Color me amazed..." I can easily work in there... Building has some insulation. (not a lot though)
Review: Excellent operation and excellent customer support - Over the summer I purchased two of these units for my 40 x 40 x 16 lightly insulated workshop building located in central SC in the country. I built my own larger, hanging brackets to move the heater farther away from the wall to allow better overall operation with better temperature sensing and the ability to rotate the units ~ 100 degrees for more flexible heat flow direction. The heaters are mounted to a 6x6 post, ~ 7' off the floor. I also removed the temperature sensor tie wrap and allowed the sensor to hang down the connected ~10" wire length for more accurate temperature sensing. I wired the heaters to NEMA 6-50P outlets using 6/2 copper due to cable length and used the DR Heater DR-PS101 power cord for flexible heater use. . https://www.desertcart.com/gp/product/B07NSV8GDG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 The unexpected cold fronts we had earlier than normal in November and December with temperatures down to the upper teens allowed a decent test of these heaters and their installations. At the beginning of this period, we rescued a stray cat (have four other rescues...) who appeared to be starving and would not have survived this unexpected weather. We fed and placed him in the workshop and turned on one heater located in his quarter of the workshop and set the temperature at its lowest setting of 50 degrees. We also provided a pet heated bed from K&H Pet Products https://www.desertcart.com/gp/product/B000ICGJZK/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 . With these two products, he is warm and happy. The one heater easily keeps that area at 50 degrees and does not run all of the time. I have yet to see the electric bill... The heater fan will intermittently cycle for a short period of time without the heating elements being engaged and seemed like a useless function and wasteful of electricity. I contacted DR Heater through their email link and received a same day response requesting additional information, which I supplied later that day. Overnight, I had received the following response from the OEM: "Hello, Thank you for the information. If you feel the fan blowing but no heat, it is because it samples the room temperature It will sample the room temperature every 5-10 minutes for around 60 seconds, it will keep doing it every 5-10 minutes" At this point, I am very satisfied with these heaters and support from the OEM.
