How large an area will this cover? Does it say it will operate at 30 degrees? I need to use it in an unheated shop and sometimes it gets cold. Thanks!

It's ideal for cold areas as its byproduct is heat. The specifications advise on the size of space, but 2000 sq ft seems to be what I remember.

Desiccant systems generally heat the desiccant to dry it out. Cool air then travels over the desiccant picking up the heat and dropping off some moisture. This one works that way; so will clearly operate at 30 degrees. We live in the humid south, and run it on high all the time. It keeps our 12 X 15 bedroom significantly warmer than expected even with the air conditioner running.

Footprint is about 11" x 13" and about 2 feet tall. Not meant for a large space.The User Manual states "Working Temp Range" 33.8 degrees F to approximately 104 degrees F.

I put mine in a 36x36 shop with 10ft ceiling that is well insulated. It has been down to 40degrees so far and heater work great. These heaters require 240 volt 30 amp circuit. I would install one now and try it knowing I may need another. The are quality American made heater.

I would look for a different width product. This one is only 20"... If you centered it in your 30" space, you'd have 5" on each side that would be unheated. While the heat does spread a little bit, you'd still feel cold spots where there was no wire... it would not spread 5"

Minimum temperature for heat? I use this in home office in 1 walled off bay in un-insulated 3 car Garage. Tonight it was 52 degrees F when I turned it on and after about 45 minutes its 64. I don't see why it'd have a minimum but may not want to try below 32? Read the manual? Might be specified... Extended warranties: Dunno....in general I never use them but have recently started for my kids cell phones but nothing else. This might be a good candidate though ...it works great after a few years but if something breaks its probably not repairable...(spare parts from China??? no Maytag repairmen on this thing???)

If the room is well insulated and the outside temperature is in the 30 degree range it wil probably heat it reasonably well. There are to many variables for a really accurate response.

I heat a 24 x 24 garage with 10' ceiling. Works great, but a bigger heater would be advised for a 30x40 building. Also depends on your location and what you have for heat loss.

We have this heater installed in an open area of our home that is 2 levels (a drop of 2 steps to the lower level) and approx 30 x 40 with an open beamed ceiling. An open hall leads off upper area and there are open doors to other rooms. It takes the chill off the entire 1500 sq foot house, is not very effective in the back 3 rooms of the house, but keeps the upper area where it is installed (30 x 20) very comfortable. I definitely would go bigger if you want it to heat your entire house, but it's great for smaller areas. It is economic to run. We are very happy with it.

Hello, I use my Mr Heater to heat a 16 x 26 area with no problem. But I have it insulated pretty good. I want to say I could run around 6 hours on a 20 lb tank? If your garage is insulated, you would be shutting it off part time. The best way is to run it thru a thermostat. TSC stores use to sell a thermostat the would work on one of these? It's a nice little heater that you would fine is pretty handy to have around.Hope this helps,RGH

I'm using mine on a patio as a slide in under an outdoor kitchen cabinet. Make sure you have about 4 inches around for air flow. This unit has the condenser built in the left and right sides and dissipats the heat unlike a fan blowing air across the condenser on your home frig. What I did do is take the 1/2 inch shipping foam that was in the box and duct tape it to the back and top to help insulate the box a little. Just dont cover any part of the outside that feels warm after it's plugged in. Here is something I want to warn you about but is no big deal. When the box is cold and say you go to get a drink out of it. After you close the door it forms a tight vacuum and makes the door almost impossible to open unless you wait 3 or 4 min. I do HVAC repair and have have seen this same thing happen on walk-in coolers trapping people. You need to make a way for the vacuum to be relieved. What I did was take a 2 inch piece of thermostat wire (this wire is about 1/2 the size of a cloths hanger) tapped it the top and bent it over to go between the refrigerator box and the door gasket. This little wire will allow the vacuum inside to equalize and you can open the door within 15 to 20 seconds and it wont bother the temperature. Buy the way this frig can freeze a bottle of pop if you set it to cold. My control is setting around 5 O'clock and running around 32 degrees. I leave it outside but unplug it in the winter. Good Luck

basically takes up only 1 cubic foot of space!...but heats up my 24 X 16 shop great with no insulation..40 degrees outside ..turn it on and it will get my shop up to 80 degrees in an hour!..great heater!

In a poorly insulated older home, it's way more than adequate for a 15 x 15 room when outside temperature is in the 30s or even lower. In a room that is twice that size, it's just not enough at these temperatures. A space heater is a necessity. Overall, in my situation after exactly one year of use, GOSH am I pleased!!

If you leave this heater in a garage when it gets to 12 degrees F outside, it will be destroyed. Ask me how I know this. I am getting ready to order a new one. You absolutely have to protect it from freezing.

This heater works as advertised. We use ours for the pontoon boat and for the work shop. The work shop is 20 square feet and on a cold day it heats it up very fast ( 45 minuets). The boat has a plastic cover that is 8 square feet and in 20 minuets on a cold day it is very warm. We have a portable or smaller version Mr. Heater with a fan and it is a great heater.

I use it in a 12x 16 ft basement workroom and the temp goes up about a degree an hour--about the same as the small kerosene heater I used to use there. But that room never gets colder than about 56 degrees and I work comfortably at about 62-64. I like it but I feel I have very specific needs.

the unit has a heat source so it doesn't seem to matter the temp of the room (above freezing). I have it in my garage and it is often in the 40 degree range. The unit does put out heat when operating (when removing humidity--if humidity is at or lower than your setting the heat turns off but fan continues to operate). You should be fine. I love this thing. I moved from Eastern WA where humidity is hardly ever above 50%, to Western Wa where it is in the 80-99% most of the time. I am allergic to mildew/molds etc and this unit keeps my home dry and no musty scents. I was prepared to purchase a second one for the upstairs but this dandy unit keeps both floors perfect.

I only used the heater for one night to take the chill off, and it did, our unit, the 12000 btu, cooled a 2100 sq ft house on a low setting of 70 and the house was at 67 degrees. I think it will do it in that small space, I am very well insulated with spray foam and 10 in thick walls, we do not have a furnace, in Iowa/Nebraska!
