2. Dyna-Glo Portable Propane Forced Air Shop Heater

dyna glot F40 salamander heaterThis heater makes the list as the best-value pick. It’s cheap but safe and most definitely our best pick for portable commercial heaters. Available in models as low as 30,000 BTU all the way up to 300,000 BTU, there’s a Dyna-Glo portable torpedo heater for any occasion. The 30,000 BTU model starts at just under 75 dollars, a steal when compared to it’s competition which starts at over 100 dollars.

This portable garage heater needs a lot of ventilation, so I only recommend picking this heater up if you have a lot of ventilation in your space or plan on using it mainly outdoors. The 60,000 BTU model (pictured left) heats up to 1,350 square feet in minutes, way more than the average sized garage. This is the best portable commercial space heater available, so I recommend checking out the review and prices for an in depth assessment of all the Dyna-Glo models.

portable indrared heaterThe first thing that caught my eye with this little portable electric space heater was the sheer number of positive reviews. It’s a best seller in the space heater category with over 2,200 user reviews. It’s very capable of heating up to 1000 sq. ft. because of its dual-heat technology. The main benefit of this portable heater is it’s use both in the garage and throughout the house. It’s safe around children and dogs because the heating elements are all inside, so the outside of the unit stays temperature controlled (not to mention it has a suitable style to fit in with household furniture).

If you need a dual-purpose space heater this one is the most cost effective and packed with features (remote, digital thermostat, overheat auto shut off, and more). If you need household portability this is the number one pick, but read the full review and check the recent price to make sure it does everything you need.

portable propane heater on wheelsThe Mr. Heater Radiant heater is a very unique design, but that hasn’t stopped it from getting lots of positive user reviews. It comes fully assembled, so all you need to do is hook it up to a natural gas line and there will be instant heat.

It’s design says it all for portability. It needs ventilation so it’s not totally safe for indoor use, but it can heat up a 750 sq. ft. room and is priced affordable. The infrared heater covers a large area with its rectangular space, so the infrared waves quickly heat up the objects directly around it. It’s a bit less portable than the other gas powered options simply due to its trolley like design, but for those of you looking for a radiant heater this is a top choice.

What’s the Best Portable Garage Heater?

This list of top portable shop heaters was created using the following criteria;

  • Portability and Fuel Type
  • Heat Ability and Total Power
  • Overall Construction and Life Span
  • Price

While my number one pick stands (the portable propane garage heater) your choice will depends on a few factors. It just so happens that every possible heater fuel type made the list (electric, propane, natural gas) and both heat types (radiant/infrared and forced air) so if you’re looking for a specific fuel type or combination that will be above. Generally they can all heat a normal garage space, but numbers 2 and 4 are optimal for mainly outdoor use.

The best part about a portable heater is there’s no set up time. All of these heaters simply require a fuel source and they’re good to go. A portable heater is often a better choice for anyone who is travelling or simply wants a back up heater in the case of a power outage. So that’s my definitive list to getting a portable space heater, I recommend checking both my detailed review and the current price to read some user reviews as well.
