It also has 2 Hot Plates on it . When you turn the heater on low 1 hot plate will heat up , and when you turn it on High both Hot plates will heat up.. This is the Best Heater to invest in.
Lightweight, easy to use, and works great! This is one of the very few propane heaters in this class to be rated for both indoor or outdoor use. I purchased it to heat my diesel tractor to facillitate starting in <20 degree weather. I was worried that it might be too small for the job compared to the larger tubular 60,000 btu type construction heaters. It worked better than expected and had plenty of heat. Its small size and indoor/outdoor dual use rating make it versitile as a back up heater in a variety of circumstances. It is also one of the few with a built-in fan which helped a lot. One note - I purchased a conversion adapter to hook up a larger 5 gallon propane tank. The instruction inside the manual clearly state that a secondary inline fuel filter is needed for this case, but there wasn't good advance warning in any external literature. I had to make a second trip to purchase the inline filter. The filter is definitely needed because the larger propane tanks are filled with unfiltered propane, whereas the smaller tanks this heater is designed for are filled with cleaner propane that has already been filtered.
works great, got this as a backup in case of power outage. It took a little bit to get the air bled out, but once I got it done, it fired right up. The built in fan works, but really doesn't move much air, although some air movement is better than none.
the heater and accessories arrived promptly with no shipping charges. the heater works as advertised, and the convenience of using the hose to connect to a 20 LB tank is more than worth the price. the heater will be used as heat on the patio and is an important emergency backup. this heater works as well as my first Mr. Heater still working after 15 years.
We own a remote cabin in the Colorado high country. I own two of these which I use to heat the cabin when we first arrive to supplement the furnace. When it is 10 degrees outside I can heat the cabin from 40 degrees to 68 degrees in two hours using the heaters, furnace, and gas fireplace. Once it's 68 I shut off the portable heaters and use the furnace and gas fireplace to maintain heat.
This model heater arrived in perfect condition well wrapped and was here in less than 24 hrs with all the features I wanted which were in sparse supply with a blower fan built-in. Driver was very professional and a great communicator. Great job Walmart!
propane gets costly, it takes quite a bit to run it for long durations. some of the directions were a bit confusing. overall once you figure it out and can afford the propane it works pretty well. i do believe it was over priced, but i bought it when it was freezing out and heaters are a necessity. obviously i purchased it in season so it was at its highest price which was barely affordable for an already struggling me whos heater wasnt working and HAD to purchase something to keep me somewhat thawed out.
Not sure how it worked since we couldn't get it to work. Once at home we noticed the box had been opened before and resealed. When we opened the box and cut open the plastic it was sealed in we noticed the heater was a used item. The problem is we thought we were buying a new heater. It still had dirt, grime and lots of scratches from the previous owner. Well, since we had an impending winter storm we can live with it as long as it works...but it didn't. After multiple tries and conferring with people who had one of these we realized it wasn't us. I mostly have a problem with Walmart rather than the product. Walmart obviously just put it in a box without testing or cleaning and resold it.
