Customer Reviews for Dr Infrared Heater 7500-Watt 240-Volt Hardwired Shop Garage Electric Heater Wall/Ceiling Mounted with Remote Controlled Thermostat

I bought 2 of the 7500 watt heaters for my detached shop. It's two bays, with a dividing wall. Big bay is 20 x 40, with 13 foot ceiling. Small bay is 16 x 36 with 11 foot ceiling. It's insulated and interior is sheeted with osb. Ceiling is also insulated and has a plastic sheeting instead of wood or drywall (it was much quicker and cheaper). These heaters use 8 gauge wiring and double pole 40 amp breakers. Let me say the 8 gauge wiring is expensive and tough to work with, as it's not very flexible and it's very thick. I started by running the wiring in rigid conduit, into wall, panel, etc. I left a chunk of wiring stubbed out where I was planning to mount heaters. When I went to wire the first heater, I couldn't do it while it was mounted 13 feet in the air. Between the tiny opening on back of heater, large, thick 8 gauge wires and wiring in flexible conduit, I just couldn't get the wires connected to the heater. I ended up pulling out all my wiring, then prewiring heater on workbench, then re- hanging it and re-running all the wiring. It sucked! When I fired up the heater, it all worked great. After about 2 minutes, it shut down. I followed trouble shooting instructions, but found it would not stay running on the high mode......so basically I spent all that time and money, and extra big wiring for a 4700 watt heater. I called the company and it took a couple days and conversations with several people to resolve the matter. Basically they said they had some units assembled with the wrong parts, so they wouldn't operate on high mode. They sent me out 2 new units (with correct parts) and included shipping labels to return old units. I pulled everything apart and installed the new units. They've only been running for a couple hours, but seem to be operating correctly. I'm not sure how expensive they will be, but hoping they will be more cost effective than the two 1500 watt portable heaters I had been using for past month. I'm in Montana and Temps have been in the 20's a lot during last month. My electric bill went up about $60 last month running those 1500 watt heaters a lot. I'm not using external thermostats. I'm sure they would be more accurate, but the in- unit ones are fine. You just need to find temp you like and use that. As an example, my heaters are mounted near ceiling, in corner of bays. I set thermostat for 55 degrees, to keep shop a little warmer during cold. That way I can get it warmed up quicker if I am out there working. If I leave the heaters on 55 degrees, the shop won't ever get that warm, as the heat stays in the high corner, so heater shuts off when it senses 55 degrees. I find that running a small fan somewhere in front of heaters helps to pull heat away and get heater to run more accurately as far as overall shop temp. I just run a small fan on a timer to help with this. Overall they seem to be well built and produce decent heat. I don't think they will compare to like a wood stove, or larger system, but for the cost, they will keep the shop usable during winter months. Installing is pretty straight forward, with some basic electrical skills.

This is a very nice heater with great features! Powerful heat, especially for a large garage! I love the remote control, also. Now I enjoy going in my garage while it is freezing outdoors!

First off, this should be installed by a licensed electrician. I also had the wall thermostat installed to control the temperature. The way mine got mounted to the ceiling allows the unit to rotate if needed, but the directions make it look like it needs to be mounted in the forward position in line with the mount. In planning for it to be rigid mounted, we installed the mount at a 45 degree angle diagonally across the garage. This was to try to evenly disperse the heat across the garage and seems to work as planned. The unit heats our 24’x24’ garage with ease. The only trouble I’ve had is that the unit self powers off when I run it in the high power mode. When the garage was nothing but open studs it could run continuously on high, but as soon as drywall went in it started shutting off by itself. I tried the low power setting and now it runs without a problem. I think on high the unit was heating the area too fast and the heater would sense it and shut off. Even if you want to use the wall thermostat you need to keep the remote control to power the unit on for the first time or if it shuts itself off for any reason. This is also how you set low/high power and set a timer on the device. Overall this is a great electric garage heater and would buy it again.

Perfect for me .work grate in my garage 26x18..

This heater does not work as advertised. We paid several hundred dollars to a licensed electrician to rewire our garage to accommodate this heater. The heater will only run for about 15 minutes and then it shuts off. I have been in touch with the manufacturer and they sent me a part that took my husband an hour and a half to put in. This part did not fix the heater. The manufacturer does not have any idea what is wrong with this heater and therefore we are left with a heater that barely works. Do not buy this heater

Hearter works great, but the internal thermostat does not. It cuts the heater off before the room reaches the set temp. The thermostat is too close to the heater. The heater should be sold with the recommended exterior thermostat.
