DR. INFRARED HEATER DR218-1500W Greenhouse Garage Workshop Infrared Heater, 1500-watt

Purchased this to keep the chill out of our outside unheated bathroom and even on the lowest setting it's a tad too warm. We will definitely keep it and use it when the temps get really low!

I’ve had one since 2018, literally almost 6 years. I’m having to finally replace it as the rats or mice in my greenhouse chewed wires. Great heater, last year I forgot and left it inside during the summer which was around 130 degrees inside if not hotter. Still worked great. Definitely ordering another and I may upgrade to larger size.

It’s a great little heater.. I have a greenhouse bubble top and the sides are polyurethane it’s about 10x10 ft If you live in the northern part of the US as I live in Michigan this will not be strong enough for temps under freezing. I have citrus plants and need the grenehouse to be at least 45 at night and this can’t do it with temps in single digits. If the sun is out it’ll stay a good temp during the day but it’s more of a concern at night. I had to add an additional heater to keep the temps up. This honestly could just be a mistake on my part as I need something stronger.. just wanted to share my experience.

The heater is well built and has sustained my makeshift greenhouse through 12 degree weather functioning on the lowest setting. I am so impressed with the overall clean technology.

Works better than I expected. On the lowest setting my tiny greenhouse stays quite warm. I only intended it to keep my baby trees from freezing because I couldn't get them in the ground in time. I need to adjust something because my spring bulbs are starting to sprout! I also purchased an InkBird(?) as per other reviewers suggestion but have not hooked it up yet. That's my plan for tomorrow since it's supposed to be in the twenties every night for the week.

This heater has an all metal case, heavy heating element and quality fan. That is hard to find in 120V heaters. Unfortunately there are significant bad reviews with photos of wires melting, thermostat burning, etc. Anything that burns up out of the box has to get 1 star and probably explains why it got discontinued. So when I received my heater I immediately took it completely apart and rewired it for use with an external line voltage thermostat (Peco TF115-001).1500 Watts is 12.5 Amps and that is really a lot of power in a heater because any defect will overheat and melt. The contacts in the thermostat are apparently rated for the load but are poor quality and apparently can't take repeated cycling of that much power.There is a thermal fuse built in which is good and probably explains why some units stopped making heat but continued to blow air. It saved the unit from a full melt down but is considered trashed. Replacement thermal fuses are not easily installed.I rewired using 14 AWG marine grade wire, crimped and soldered connections and a heavy cord and plug. I reconnected the thermal fuse but took out the thermostat and switch. That removes the problem areas completely. Again, this setup is for use with a good external thermostat. The fan should run continuously while in operation.A few weeks later, I ordered another unit and rewired it differently. I used an HVAC contactor (Eaton C25BNB230A). This contactor is designed for repeatedly cycling a 30 amp load. The original built in thermostat and switch drive the contactor and fan and now has much less power going through them. As before, I upgraded the connections and wire. See my photo. Later, I wired in a GGXAC1F480 NOsparc Arc Suppressor to protect the contacts. Now this is a 5 star product.These modifications are not something you should attempt unless you have electrician skills.The good news is the price on open box returns keeps going down so I bought a couple more and rewired them too.

This little heater is perfect for my small greenhouse. This was my third attempt at finding a heater that works correctly and maintains the right temperature. Even in below freezing temperatures, this heater keeps my greenhouse at a consistent temperature and all my plants (even tropicals) are doing great! Would definitely recommend!

My first one worked great for about one winter then it just stopped and would not work at all. The seller replaced it quickly. The second one worked about one winter then it just stopped heating. The seller sent a new piece for me to install. I got that installed and it still does not heat. I have emailed the seller THREE times and have yet to hear back from him. Loved it when it worked but lots of money for one that doesnot last a whole season. It’s been months with very cold weather and still no response from the company. VERY DISAPPOINTING, BUY AT YOUR OWN RISK!!

This was the second unit I bought, the first by a different company, which I returned. This one seems to work perfectly. Ive had it running in my little greenhouse for a month and it works perfectly. Even the set up and thermostat is intuitve and obvious

Todo de acuerdo a lo solicitado, Super bien

good

This little heater does heat my 8 by 12 greenhouse. I have to see how much running this heater will cost me on a monthly basis. But my tomato plants are doing well with the added heat at night.

Plugged this "greenhouse/workshop" heater into my garage workshop and it wasn't blowing any hot air just cold.Tried several unplugs and plug in again, to no avail.Called the manufacturer, she suggested that I wait 1 hour and it might begin blowing hot air. This was ridiculous as it was advertised as instant heat.Sent it back to Amazon, Waste of money at $218.00.
