The perfect heating of this propane portable heater for the garage helps you to keep warm while you working. Mr. Heater F215100 MH4B Little Buddy has automatic ignition, and you can turn it on by flipping the switch. 

From that moment, you can utilize one of the two settings the unit offers. The low-heat option delivers 4,000 BTUs per hour, while the high-heat mode can produce 9,000 BTUs. That should be enough to warm up a portion of the garage that’s approximately 100 square feet large.

The idea of this unit is not to heat the entire garage at once. Instead, you take it with you to the area where you are working and place it close to you. It is lightweight and comes with a ceramic burner tile and a wire guard to protect you from high temperatures.

You can choose between four positions to ensure the right heating angle. It also has tip-over and low-oxygen protection features. This propane radiant heater for the garage is my personal favorite.

Larger models are available if you need to heat bigger areas. Overheat protection is among the safety features of the unit.

This portable RV propane torpedo heater comes with a regulator and a 10-feet hose. However, you will need to purchase an LP tank to run it, and the minimum required is 20lb. According to my personal experience, this is one of the best portable propane garage heaters on the market right now.

How to Choose The Best Garage Heater

You’ve decided that a propane heater is the most suitable choice for your garage. However, you still have no idea which unit you should purchase. If that is the case, here is how to choose the right propane heating appliance for your needs.

Consider the Space You Want to Heat

Take a look around and observe your garage. Is it a small space that is relatively well insulated? If that is the case, you might not need a powerful heater, and only a moderate heating appliance will do. On the other hand, if you have a large garage that tends not to keep the heat, you should consider a heater that is more powerful than usual.

The same goes if you are living in a cold climate. We will discuss the sizes and BTU power of propane garage heaters later. However, the general rule you should follow is that the bigger your garage, the bigger the heating appliance you need.

Do You Need a Portable or Fixed Heater?

When it comes to options that you have for heating your garage with propane heaters, two types are at your disposal:

  • Portable propane heaters for garage.
  • Fixed propane heaters (wall-mounted or ceiling-mounted)

Portable propane heaters are perfect for small spaces. Although they provide only moderate heat, it should be more than enough. They are also useful if you don’t spend a lot of time in your garage. They can heat the space quickly, and you can take them with you to the corner of the garage where you are working. 

On the other hand, fixed propane heaters offer more heat, and they are an excellent choice if you frequently use your garage. You can mount them on the wall or ceiling and make use of the propane gas line already running through your house.

Safety Features

When using a gas heater or gas powered fireplace indoors, you need to make sure to take all the safety precautions. For starters, you need to read the instructions carefully. See if the appliance requires you to ventilate the room and do so accordingly. Alternatively, choose a heater that doesn’t require ventilating.

Always look for a model that is rated for indoor use. You don’t have to worry about the ones you find in the reviews in this article. As for other safety features, thermal overload protection and protection against tipping over the unit are always welcome.

What about the Cost?

The truth is that propane garage heaters are not necessarily expensive. In fact, the portable models are quite affordable, and I’m sure you can find the one that fits your budget. I also urge you to consider not only the initial cost of the heater but how much it costs to run them. It’s a good idea to look for highly efficient models as they tend to spend less fuel. Know more here.

Automatic or Manual Ignition

If you are looking to make things easy for yourself, find the models where the fuel ignites automatically. These models are turned on by just flipping a switch, and they start heating the garage in seconds. On the other hand, there are units with manual ignition. But why would you bother to ignite the fuel yourself when there is an automatic alternative?

Frequently Asked Questions About Propane Garage Heaters

How To Cool My Garage?

  • Park your car outside if it was recently used.
  • If you are on a tight budget, use a fan (ceiling fan, box fan, pedestal fan, etc.) or a window.
  • If you have enough money, improve the ventilation system of your garage or implement air conditioning.
  • Use a dehumidifier.
  • Make sure the garage is insulated correctly.
  • Use lighter colors for the exterior and door of the garage

Where Should I Put My Garage Heater?

If you bought a portable propane heater, you could take it with you anywhere in the garage as long as it is not close to combustible items. For direct-vent fixed heaters, it’s crucial to secure that they can be connected to the propane gas line running through your garage.

How Much Does It Cost to Heat Your Garage?

You will need to start by investing in a heating option. These include:

  • Electric heaters
  • Natural gas heaters
  • Propane heaters

The last one is undoubtedly the best option as it delivers the most heat at the most affordable running price. 

However, if we are talking about heating your garage, you also need to consider that it has the proper insulation. There is no point in heating the space if you lose all the heat due to poorly insulated space. That is why investing in insulation can save a considerable amount of money in the long run.

How Much Does It Cost to run a Heater in a Garage?

It depends on the power of the model. If the heating unit delivers more heat, it probably costs more to run it. You should look for highly efficient models to save some money. 

How Many BTU Do I Need to Heat a 2-Car Garage?

It depends on the size of your garage and the usual weather conditions outside. However, an average 2-car garage has approximately 500 square feet of space. That would mean you need around 45,000BTUs to heat it. 

How Much Does It Cost to Have a Garage Heater Installed?

You might not need installation at all. If you choose a portable propane garage heater, it might come pre-assembled. However, if there is some setup involved, you should be able to do everything by yourself if you follow the instructions carefully.

On the other hand, if you don’t think you are up to the task, it might be best to hire a professional. Direct-vent fixed propane heaters can be tricky to install. It might cost you a bit to get a helping hand, but you will save yourself the time and hassle.

Venting Garage Heater through Wall – How?

When setting up a garage heater, you want to ensure proper venting. The best option is to vent it through the wall. Alternatively, you can go through the roof, but you will lose far less heat if you choose the wall option.

You just need to make a hole in the wall and pass the combustion exhaust pipe of the heater through that hole. That is how you will secure your garage is adequately ventilated at all times. Once you do that correctly, you don’t have to worry about venting anymore.

Propane Garage Heater Sizing Guide

You don’t want a buy a heater that is too small for your garage because you will end up being cold whenever you are in there. However, you don’t want a buy an appliance that is too big or powerful because you will overspend on running costs. It’s a tricky task to find the right balance, but here is how to correctly size the heater for your garage needs.

So, the basic thing is choosing the best propane heaters for your garage isn’t going to solve your problem or keep warm your garage. You have to choose the best and right one. Here goes my calculation about which heater going to be best for what size of garage.

Start by measuring the size of the space you are planning to heat. In this case, it is your garage. Your goal is to calculate the square footage. To do so, you need to multiply the width of the interior by its length.

Let’s say that your garage is 25 feet wide and 20 feet long. That would mean you have 500 square feet that you need to heat. 

Now, you need to determine the total amount of cubic feet you want to be heated. To do so, multiply the floor space with the height of your garage. Measure the height from the floor to do the ceiling and do the math.

In our case, we have a 500 square feet garage that is eight feet tall. That would make the calculation 500 x 7 = 3,500 cubic feet that we need to heat.

The next step is to determine the temperature rise. Think about the heat level you want in your garage. Let’s say you want it to be 70 degrees when you are inside. Now, consider the lowest outside temperature during the cold season.

Let’s say that it is 50 degrees. Finally, calculate the difference 70 – 50 = 20. The temperature rise you want is 20 degrees.

The final piece of the puzzle you need is insulation. This is something you would need to observe and try to appraise yourself. In general, the rule is to use “0.5” if the insulation of your garage is excellent, “1” if you believe that it is average, “1.5” if it’s inadequate and “5” if there is no insulation whatsoever.

Finally, use this equation:

Insulation * Cubic Feet * Temperature Rise / 1.6

In our case, the garage is averagely insulated, which means that we calculate like this:

1 * 3,500 * 20 / 1.6 = 43,750

This number is the amount of BTUs you need to heat the garage. That is how you will choose the size of your heating appliance. The unit that can deliver that much heat is the one that you need.
