Sometimes your projects will take you places, but if you’re not prepared to work in the cold weather you’re going to have a bad time! A portable garage heater is an easy solution to this, bringing the heat to anywhere you need. Portable garage heaters are generally more powerful than simple portable space heaters you’d find in the house. They’re fueled with either gas (natural, kerosene, propane) or electric. The most portable option is gas, as portable electric heaters will require an extension chord, but it all depends on your garage needs.

Below is a curated list of the best portable garage heater reviews. These top rated portable heaters are good, efficient, and very durable for on the road use. They are cheap (easy on the wallet) but safe heaters. Most of these options even have added safety features allowing them to be used indoors.

Top 5 Portable Garage Heaters


#1 – Mr. Heater Portable Garage Heater

This portable garage heater is top rated for heating any garage. It’s a number 2 seller on Amazon of all the garage heaters thanks to it’s powerful propane fueled heat and because it’s able to be used indoors (heats up to 400 sq. ft.. At the time of writing the Mr. Heater ‘Big Buddy’ has over 1400 positive customer reviews, so it must be doing something right.

This is the best portable space heater because of it’s rugged design, price, efficiency, and portability. It’s shell can take quite a beating so you can definitely throw it a truck filled with tools without worry. On a single propane tank this portable heater can last over a week and lasts up to two months on a 20 pound propane tank. It’s also the only propane heater that is safe for indoor use thanks to it’s built in oxygen level sensors.

                                            

 

#2 – Dyna-Glo Portable Propane Forced Air Shop Heater

This 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.

                                             

 

 

best electric garage heater overall

#3 – Dr Infrared Portable Electric Space Heater

The 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.

                                             

 

 

#4 – Mr. Heater Portable Radiant Garage Heater

The 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.

                                             

 

#5 – Mr. Heater Portable Natural Gas Workshop Heater

This portable vent-free heater features a natural gas powered blue flame heat. It has multiple safety features (such as oxygen level sensors) making indoor use is no problem, whether that be the garage or the house. This portable gas garage heater is very powerful and can heat a space as large as 1000 square feet in as little as 10 minutes.

It can be portable and stand alone but just as easily can be wall mounted. With a whopping 30,000 BTU there won’t be many garage workshops this natural gas heater can’t warm.

                                             

 

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 ) 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 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.
