The 8 Best Propane Heaters for Your Garage in 2018

Motorbike in Garage

Propane Heaters are a fantastic way to keep your garage useable all year round.

They are cleaner than kerosene heaters, and pack more power than electric heaters (our guide to those here).

Not requiring a plug socket means they are unbeatable in portability, too.

No matter the size of the heater, all you need is a place to put it and a propane cylinder to fuel it. Get caught in a power outage? No sweat. They’re also fantastic back-up heaters.

One thing to note is that you need some ventilation in your space. Even cracking open a window can be enough: don’t worry about losing some heat. You’ll have plenty of that.

Worried about not having enough ventilation? Make sure you pick up a gas detector, too! See the top recommended options on Amazon, and brush up on some top tips from FEMA and CENEX.


What’s in this article for me?

In this guide, we’ll walk you through the types of propane heaters that are excellent for heating your garage.

There are three main types of propane heaters:

  1. Forced-Air – the iconic cannon heaters that blast out hot air 
  2. Convection – ‘barrel’ shaped heaters that spread heat in every direction
  3. Wall-mounted Blue Flame – ‘radiator’ heaters that save space by mounting to a wall

For each of these three types, we’ve compared the models from the two best companies for propane heaters. [Dyna-Glo, and Mr Heater]

(No, we’re not sponsored by them – or anyone!)

Both of these companies, in our opinion, produce the best propane heaters on the market. They both offer a great blend of quality and durability, without excessive price tags.

But first, it’s important to understand how we measure the power of these heaters.

All propane heaters are measured by BTU’s per hour.

What are BTU’s, and how many will I need?

Calculator pen and paper

Some quick maths required for best results..

BTU stands for British Thermal Unit

This isn’t how much power it takes to brew a British cup of tea..

A British Thermal Unit can be defined as:

The amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit

from howstuffworks.com

When a heater has a rating of, say, 14,000 BTU – that means it can heat 14,000 pounds of water by one degree Fahrenheit, per hour.

We can change this to air, and find out how much we need for your space, by following the simple sums below:

To find the amount of BTU’s you need, use the following:

1. Find the cubic feet of your space (length x breadth x height).
(say 25x25x12 = 7,500 cubic feet)

2. Estimate the coldest outside temperature, and find your ideal room temperature
(say 30°F and 70°F)

3. Subtract the cold temperature from your goal temperature
(70°F-30°F = 40°F)

4. Multiply the both of these together and by 0.133 for Farehenheit, or 0.2394 for Celsius
(40 x 7,500 x 0.133 = 40,000 BTU for a 25′ x 25′ garage with a 12′ high ceiling)

5. Use our recommendations below to find a matching propane heater!

 

Now without further ado, let’s get on to the heater reviews..

Type #1: Forced-Air Propane Heaters

Dyna-Glo Heater in Attic Workshop

The immediately recognisable ‘jet engine’ look.

These are the iconic propane heaters that are always such great talking points.

They look more like they should be strapped to a jet fighter, not used in a garage.

They produce a huge amount of heat with a direct airflow – perfect for heating garages or workshops.


Best Forced-Air Propane Heater:
Dyno-Glo RMC-FA60DGD

Dyna-Glo Liquid Forced Air Propane Heater

Best all-around quality and fantastic looks – our top pick.

One of the greatest things about these forced-air heaters by Dyna-Glo is the wide range of models available.

With 5 liquid propane heaters on the market, ranging from 40,000 BTU all the way up to 300,000 BTU, they can suit any size of space.

Each of these heaters include a 10-foot hose and regulator, and the adjustable angle means it’s easy to get the airflow right where you want it.

The build quality is solid. A ‘construction grade’ base keeps dust and debris out, giving the heater a longer lifespan. Safety shut-off switches come as standard, both for tip over and overheating cases.

The only downside of these heaters is that the warranty is only 1 year. However, this is standard for heating products.

If you’re looking for a forced-air propane heater, these Dyna-Glo models are an ideal option.

Mr Heater Models

A close second. Mostly due to looks (our opinion)

Another excellent choice for forced-air propane heaters are these Mr Heater models.

The largest difference between these models and our first choice is the range of options, but also the looks. With a jet-black finish and bright coloured decals, these heaters have a much bolder look to them.

The same great features are included – a 10 foot hose and regulator, fully variable controls, safety shut-off in-case of overheating, and a warranty that lasts a year.

They exhibit everything that’s great about propane heaters.

If you prefer the sleek black finish and there’s an option to suit your space, these are excellent heaters that are well worth the money.

Runner-up: 

ProTemp Models

ProTemp 60000BTU Forced Air Propane Heater

Smaller package, lighter weight, same power.. but a higher price.

We were originally going to list just two models, but this Pro-Temp has every right to be on our list, too.

At the time of writing, it’s price is a fair bit higher than the models above. The higher price rewards you with a heater which is smaller, and weighs less than the equivalent models above.

Weighing in at just 11.2lbs vs. the Dyna Glo’s 16.8lbs – this heater is much easier to handle and move around. However, we just aren’t sold on the color or extra price. Unless you’ve got an tightly packed garage or find that this one is on sale, it doesn’t quite make our top choice. But it’s still a great option.

Check out the Pro-Temp Models on Amazon here.

Type #2: Convection Propane Heaters

Convection heaters are a great option for heating smaller-sized garages or workshops. They radiate heat in a 360° radius.

If you’re able to place them in the center of your space, they are fantastic at quickly heating up a room. Their variable temperature gauges also make it easy to control the heat – something you’ll be thankful for once they really get going.

While they don’t look as powerful, they range up to huge levels of heating power. Up to 200,000 BTU.  (Enough to heat a 50’ by 50’ space!)


Best Propane Convection Heater: Dyna-Glo

DynaGlo Convection Propane Heater

Excellent quality and sturdiness – our top propane convection heater

Once again, Dyna-Glo have taken the top spot.

They’ve maintained the same excellent level of quality that also put them top for the forced air models. The wide, sturdy base is great for stability – but the safety switches are still there just in-case it does get tipped over.

They offer three levels of BTU capacity:

  • 25,000 BTU
  • 80,000 BTU
  • And 200,000 BTU

Runner Up: Mr Heater Convection Heater

Mr Heater Convection Propane Heater

Another close second, because of the narrower base

Coming in at a close second is the Mr Heater convection heater.

These are very similar to the Dyna-Glo models, and are only in second place due to minor differences.

If you prefer the look and narrower size of these heaters, they’re still fantastic products.

These propane convection heaters have the same great features – a 10ft hose and regulator included as standard, and auto shut-off safety features in the event of tipping over or lose of flame.

Our one gripe with this model is that, while the base is still sturdy, it’s narrower than the Dyna-Glo model. This means that the heater is easier to knock over, versus the more stable wider base of our top recommendation above.

Type #3: Wall-Mounted Propane Heaters

These wall-mounted propane heaters are a fantastic solution if you have a smaller garage.

While they aren’t as powerful (typically topping out at a max of 30,000 BTU), they are incredible at saving space while offering all the benefits of a propane heater. They have all the conveniences of an electric heater – without requiring any external power. They’re also ideal for strategically warming small areas, rather than trying to heat a whole space.


Best Wall-Mounted Propane Heater: Mr Heater

Mr Heater Blue Flame Wall Mounted Propane Heater

Fantastic quality and top overall customer satisfaction

As far as wall heaters go, Mr Heater comes out blazing in first place.

They offer three models: 10,000, 20,000, and 30,000 BTU.

Each of these models have a CSA-certified auto-shut off systems in-case oxygen levels are detected to have dropped too low. They also include the legs and a wall-mounting bracket, as well an easy-to-use thermostat for temperature control.

While these models are very similar on paper to the Dyna-Glo equivalents below, the inclusion of a thermostat and better customer satisfaction rating puts these Mr Heater models up to our top spot.

Check out the Mr Heater Wall-Mounted Propane Heaters on Amazon using these links:

10,000 BTU (150 sq. ft)

20,000 BTU (310 sq. ft)

30,000 BTU (470 sq. ft)


Runner Up: Dyno-Glo

DynaGlo Blue Flame Wall Mounted Propane Heater

Only second based on overall customer reviews. Still a fantastic choice.

Just like the Mr Heater models, Dyna-Glo also offer three models: with 10,000, 20,000, and 30,000 BTU capacities.

Similarly, they also include legs and wall-mount brackets, and CSA-certified oxygen shut-off features. While they don’t include a thermostat, they do have easy-to-use manual controls to help get the perfect temperature.

Though the Mr Heater models above do have better reception with customers overall, these Dyna-Glo heaters come in at a close second. If you prefer the whiter look of them to the Mr Heater models, have no hesitation in picking one of these up.

Tiny Alternative: Little Buddy 3800-BTU Indoor Safe Propane Heater

MrHeater Little Buddy Propane Heater

The ‘ultimate’ in portable heating. Take this little guy anywhere.

It’s not a conventional propane heater, but we had to include this ‘little buddy’ in our top list.

This small ‘countertop’ propane heater can put out an impressive 9,000 BTU worth of heating power. If you don’t need that much, there’s also a lower setting at 4,000 BTU. It won’t heat a full garage, but it’ll keep a small area cosy enough to work or relax in.

We like to think of this as a truly portable heater.

A fold-down handle, small cylinder, and slide-away fuel connection make it easy to fit in travel baggage. It’s effortless to take this compact heater anywhere.

Fishing, hiking, camping, boating, the moon.. we really do mean anywhere!

And just because it’s small, doesn’t mean it’s not safe. The oxygen detection and tip-over detection shut off switches are built-in, just like they are in any of the larger propane heaters.

We think this is a fantastic alternative model for anyone looking to prioritise the portability of their heating. While it shouldn’t be your primary source of heat for a garage, it can be a great extra addition or travel companion.
