Have you ever dreamed of having a fireplace in your home to keep you toasty in the winter months? Fireplaces are great but unless you have a steady stockpile of firewood, they tend to just gather dust. Duraflame has come up with an elegant solution for anyone who has ever longed for their own fireplace or anyone who simply wants to warm up a large room. The Duraflame 3D Infrared Fireplace Stove puts out 5,200 BTU’s of heat which makes it capable of warming a room up to 1,000 square feet.

It is shaped and designed like a small, rustic, cabin-style stove furnace but there are no actual flames. Instead the Duraflame 3D Infrared Fireplace Stove uses a quartz heating element and infrared heat technology to warm extra-large spaces all while displaying realistic 3-D flames inside the glass enclosure.

You can adjust the built-in thermostat depending on how warm you want it and control the whole unit with the included remote control. And if you just want to see the flames dance without the heat, you can set it to a no heat mode. The whole thing weighs 28 pounds so it’s not too heavy and stands only 24 inches high.

  • Auto shutoff safety feature
  • Doesn’t rob the air of humidity

This is another forced air space heater from a manufacturer known for making rugged, long-lasting and powerful tools. While this space heater was designed for large construction sites, we couldn’t resist trying it out in our backyard. That’s because the DeWalt DXH190HD puts out a whopping 190,000 BTU’s which makes it capable of warming spaces that are up to 4,200 square feet.

Needless to say, you aren’t going to want to run this beast indoors. It was designed for construction sites and will turn any indoor space into an oven very quickly. It runs on kerosene which the tank holds 14 gallons of. That gives this DeWalt forced air heater a run time of about 10 hours. It features a rugged design, easy to ignite switch/dial system and wheels for easy transport.

  • Runs on kerosene or diesel
  • Safety shutoff feature
  • Great for outdoor use

This heater can hold up to 5 gallons of K-1 kerosene and on a full tank it lasts for about 14 hours. But it’s not hard to tell when you need to refill because there is a clear gas gage right next to the gas cap.

The Dyna-Glo KFA50DGD is easy to refill when the time comes and has a top-mounted handle so you can easily move it from room to room. The whole unit only weighs about 26 pounds without a full fuel tank and starting it up is as easy as flipping a switch. This space heater would be great to keep the RV warm while you are camping or to make a drafty den more comfortable in the winter. In fact, we used this space heater in our garage and it worked so well that we totally forgot that it was 38 degrees outside.
