This is a well-built and effective unit. I carefully investigated many competitor units and settled on this one. At the price, I am very pleased. My shop is 25x25x12, making the volume of the heated area 7,500 cubic feet. I mounted this unit on the ceiling and it keeps the shop at the selected temperature with ease. I like the remote control features, and the timer is real energy saver. Installation was easy (I am a handyman) and it looks great.

I'd been thinking for a long time about installing a heater in my garage. I'd looked at several brands and the Tempware product seemed better reviewed than some much more well known names. The only question was whether to go with the 7,500 or 10,000 watt model. While poorly insulated and with somewhat drafty doors, at about 730 square feet, my garage is about half the size that Tempware claims this heater will cover. The ceiling is low and space at a premium, so the 7,500 watt heater it was.You absolutely must have decent electrical service coming to the location where you want to use this heater. If you don't, you may end up heating things up in a way that you won't appreciate. If you aren't sure, hire an electrician.The good: this heater definitely takes the edge off. It was not difficult to install. The manual is pretty well written. If you're moderately handy and understand the risks of working in an electrical panel on a high current circuit, you can install this yourself. I opted for the remote control model, and the remote control has excellent operating range. You'll need to provide your own batteries for the remote. I felt pretty confident allowing this heater to run unattended (doing so is most definitely at your own risk). It does what Tempware says it will do (240 volts x 31 amps = ~7440 watts). You may get a bit more or less out of it depending upon the line voltage coming to your building, though this will not be a huge difference. The control board (see further comments below) is pretty well made and uses components that should be heavy enough to stand the load and last a decent amount of time.Set to 45°F, with a low of 0°F outside while the wind was blowing briskly, the heater actually did cycle and stay off for a while in spite of the poor insulation and drafts. I set up a thermometer as far as I could get it from the heater, and the garage never got any colder than 36°F. I don't think it would have kept things much warmer than that. I didn't need it to do anything beyond taking the edge off. If you're not sure, have a poorly sealed space or are right on the point of jumping up to the next size, you probably will want to do so.The bad: when cold, the fan motor takes a while to reach full speed. There's only about 1,200 watts difference between the "high" and "low" heat settings. The thermostat bottoms out at 45°F (~7°C). I would have liked to set it at 40°F. While not really a "bad" point, you should consider what it will cost to operate one of these heaters. They are essentially 100% efficient at turning electrical energy into heat. With the large amount of energy used, there may also come a substantial cost if you use your heater often. With the cost of electricity here, I figure that it cost me a shade over a dollar (about $1.30) per hour to run this heater.What could be better: build quality is pretty good. The only quality control issue I noticed was the power supply controller chip (used to produce the low DC voltage needed by the control panel and remote sensor) was not fully seated in the board when it was soldered into place. The internal wiring strikes me as a little lightweight for the load it's under. A slightly more powerful fan would certainly help to spread the heat around. If you plan to clean dust out of the heater, be careful when removing the rear fan grille. That's where the temperature sensor is attached, and if you damage it, the heater may refuse to operate. I would like to see more range between the low and high heat settings, and maybe even a "medium" setting.Time will tell how this heater holds up and I will update this review accordingly. As things are right now, I would definitely buy Tempware again.

The Heater will heat up a 2-car garage in about an hour (from 45 degrees to 60 degrees).The heater is relatively quiet, measured at 60dBA at 3' from the front of unit. Installation is relatively easy, hang the bracket with the screws provided and mount the heater to the bracket with the 4 thumb screws. (make sure you add the wiring first, since the bottom of the unit must be removed, and this is much easier to do on a workbench)

The wiring is easy. The fan is quieter than I expected, but after a day it’s making a wobbly type sound. The sound isn’t loud enough yet for me to look into it.

Item was well packaged having 4 plastic reinforcing corners on the bottom of the box. Despite that, the foam that is packed in the box was cracked all around indicating the typical rough handling of packages we have come to expect from the delivery service in our area. I mounted the bracket 16" off the back wall of my garage, which lined up with a ceiling joist. I had a 50' piece of #10/4 SOOW cabtire with a 230V Hubbel twistlock connector in the middle. I wired it directly to a double 40A GFCI breaker that I had previously used to run the hot tub I no longer own. While I had the bottom off, I noticed some of the wires that went up into the heater section were bearing quite tightly to the edge of the access holes in the main heater floor panel, so I installed rubber grommets in the holes and manipulated the wires so there is now less tension on them. After installing the bottom cover and powering it up, there was a slight smell from the first-run of the heating elements. Just a note that there is no instruction manual with this unit, so if you don't feel comfortable around electricity, don't try to wire it up yourself. For the ground "bolt, I just split the #10 stranded wire in two equal sections and twisted them around the shank of the bolt. I had previously added a larger diameter washer to the bolt to ensure the ground wire was fully captured. I was unaware how the 3 switches worked initially, but if you look at the wiring diagram, it shows switch 0/I as one heater element and the fan, II and III are just additional heating elements. From reading the advertisement of a different heater (same features, just different colour) I understand that the O/I switch is 3000W, then switch II brings it to 4000W and all 3 switches make 5000W. I can tell you that with the thermostat set at 1/4 of the way the switches at the 4000W setting, it heated up my garage overnight (about 6 hours of running) to the point where everything in my garage was at. or above room temperature. When I checked current flow through the cable, it was reading about 18A. I have since been running it on the low temperature switch and left the thermostat at the 1/4 of the full sweep of the dial and it's toasty warm in my garage.This unit replaced a 120V 14" infrared heater that was encased in an aluminum body, (like a big halogen flood light, only emitting a red light) having a tempered glass window. It got really hot if you were too close to it. I ran a 6" 3-speed fan behind it to provide some convection and it would warm the garage ok, but even overnight, my tools hanging 10' away behind my workbench would still feel cold to touch. This is not the case with the new heater. It's pleasant to be in there now, even when the overnights were -12 here, the whole garage is warm because everything gets heat-soaked. I have read in some comments that the fan motor may be loose, etc. I did not check every screw, but I definitely will to be sure. I would rate this as a 4.5 stars only because there was no manual included to explain the operation.Update: 1 month laterThis unit is still working great. We have had some very cold spells in the Niagara region this winter and it's so nice to open the garage door and feel a wave of heat coming up from under the door. I figured out the operation of the 3 switches. Each switch engages a separate heating element, so if you need to heat up the space very quickly, flip them all on. I will turn the thermostat almost all the way down when I am finished in the garage for the day and leave just the first switch on.

Like y'all I needed supplemental heat in my unheated garage. The 400sf garage is insulated and has a quality door and window so has never dipped below freezing, but I have 2 chest freezers and a fridge in there so I want to keep the temp above 10C, preferably 13ish. I wired this unit is using 12AWG and it works great! I am using it on the 3000W setting and the thermostat is at 8 o'clock and the temp bounces between 12 and 14. The thing barely runs! Couldn't be more pleased. I figure it is costing about $0.25 a day when the temp outside drops below 12C. Totally worth it. There is also a ceiling fan in there running on low which helps I am sure. It costs $0.05 a day and runs 24/7. Considering the cost of food, this is no-brainer insurance.

So far it works great, keeping our 24 x 24 garage space warm. I have it set at 60 degrees F but it can be set higher. It was fairly easy to install, but I had to get an electrician to wire it, which adds to the cost. The only complaint I have is that the loafers don't angle down enough to push the heat toward the floor.

I had this installed with 10/2 wire added a 240v thermostat turned on the power and it ran for 12mins then stopped. Power lamp is out so went down to the check the breaker, it’s tripped felt the hot wire and it was very hot. I’m lucky my breaker was good or this could have caused a house fire.. this heater is defective and not work the fire risk. All I wanted to warm my garage so can work on my car in winter. Too bad.

FIRST IMPRESSIONThe unit seems fairly well constructed although the sticker on the front with all the buttons/labels was half peeling off but easily stuck on again. The unit it shockingly light and small for what I expected a 220V 7,500 watt heater to be. The terminals on the connection block don't feel extremely sturdy although they did the job. One of the heating element grates were bent but didn't seem to affect safety/functionality. We connected a 50 amp range cord to the unit that would connect to the NEMA14-50 outlet we had installed by our home builder for this very purpose. As recommended, we popped in a 40 amp breaker and flipped the switch. Worked great.CONDITIONSBecause a heater's performance can be dramatically affected by the environment, I'll spell out the conditions in our garage. We mounted it in a 13ft tall, 26x26 partially (attached to home) insulated garage that has a doorway left open to a standard 9ft 22x22 partially insulated garage. The primary garage to heat is 676sqft and the other garage is 484sqft for a total of 1160sqft of garage. The unit is mounted roughly 9ft off the ground in the 13ft garage. Ambient temps outside are 37 degrees today and we ran the unit on high for 2 hours. By the 1 hour mark it had taken the garage from 41 degrees to 50. By the end of hour 2, it was only 55. (Please note - the temperature was taken on the opposite side of the garage, roughly 5ft off the ground) The thermostat on the heater never read above 67, which tells us it was struggling with the size of the garage.When standing on a ladder, it became immediately obvious that all the heat was sitting about 7 to 8 feet off the ground, and a ceiling fan in the garage would do wonders for pushing that heat down. Still, I'm questioning if this unit will be enough with an uninsulated garage this size. I'm sure that insulating it would definitely make a difference but I'm not out in the garage enough to need that. I just want to keep the garage at 45 to keep everything from freezing and simply need some heat blasting in the half hour I'm doing any projects outside. I'm not a fan of turning on a heater for 2 hours before i'm gonna be out there to get into the mid 50s, plus in Ohio, high 30s outside is pretty warm for winter. Usually we're close to single digits to teens this time of year, and that has me much more concerned how this would perform under those colder conditions.FUNCTIONALITYThe very best part about electric heaters is that you immediately get very hot heat. Within 15 seconds it was blowing nearly 200 degrees. 2 minutes later it was in the high 300s. This heater makes quick work of spitting out that heat.It has 4 modes, Fan only, Low, High and Eco. It might be a stretch calling Eco a mode as it more or less switches between the other 3 modes depending on the conditions in the room. I found it a little useless personally, so I stuck to low and high. Fan mode does just that, blows only the fan without any heat, Low mode turns on most of the heating elements and high turns them all on. As I'll explain down in the cost section, low mode only uses 15% less energy than high, so it might simply leave one of the heating elements off. I found that pointless as it barely saves any money but somehow feels like it's putting out A LOT less heat. I would have preferred a low mode that were closer to half the cost to run. To no surprise, High worked best of all, but of course costs the most to run.Of note, the fan does NOT change speeds on any of the modes, it just uses less/more heating elements which make up for the cost difference. If I'm being picky, I feel like it's a little on the weak side. Would have been nice to have seen a little more oomph to push all that heat farther out in the room.When turning off, the unit, it will run for 90 more seconds to cool off the elements enough to shut down. It even counts this 90 seconds down on the temp display, which I thought was a pretty cool touch. Most manufacturers do NOT recommend cutting power to heaters immediately (via an external power cut-off) except for emergencies for this reason, as cooling the elements off both affects longevity as well as safety of red hot elements.The remote is simple and not confusing at all to useEFFICIENCY/RUNNING COSTEveryone keeps asking how much this unit costs to run so I've decided to post some cold-hard, no BS numbers captured with our energy monitoring software we use. Your own cost to run may vary wildly depending on your electricity rate, but I've included pictures of the wattage/cost for all 3 modes. These are based off our electric rate of $0.16 per kW. Fan only mode draws 38 watts and barely costs $0.01/hr. Low runs about 6,350 watts and costs roughly $0.92/hr. Lastly, High will pull the full 7,500 watts and will be around $1.09/hr. Low mode only draws about 15% less energy than high, so I found the savings to be moot when the heat put out feels like about half. In the 2 hours we ran it, the cost averaged out to about $0.15 per degree raised from 41 degrees. That number can grown very quickly as you get below freezing and into the single digits/zero.SUMMARYI was very happy with the performance of this heater, although I've spelled out quite a few reasons why it isn't what I was hoping for in our situation. We're presented with a couple of options to solve our issue with this unit under-producing for our needs (A) We can either buy a ceiling fan for the garage that will push a lot of that hot air down making it much more efficient and likely much closer to the size we need, (B) We could insulate the garage (which would be substantial cost) or lastly (C) we can just try the 10,000 watt unit, which will run roughly $0.38 (or 25% more) per hour more. Given that Amazon gives your free returns for 30 days, we will likely try the 10,000 watt model and compare their performance, then return whichever we don't feel like keeping.Granted we only used this heater for one day, but my initial impression is 5 stars for anyone with a smaller garage/workshop with lower ceilings and/or insulated walls. If you've gotta overcome 1 or both of those issues, you may need a bigger unit or a ceiling fan to make it work for you.
