I want to show you the best option for selecting the best garage heater for heating your garage or any large space. Before I dive in, it's important that you know......

Things To Consider When Buying Garage Heaters

You can toil for days looking at garage heaters and failing to buy even one. You are not alone; at once I was in your shoes. It is a common thing happens to first time buyers and even veteran.

Today I want to show you the factors that you need to consider before you shell out your cash to buy a garage heater.

Types of garage heaters

They are many types of garage heater and each has different heating capabilities.

Fan-forced garage heater

Most people buy fan-forced heater and this explains why they are so common. These types of heater have an integrated fan.

What the fan does is to blow a stream out hot air outside so that you feel the warmth, the moment you turn it on. The air is passed on a heating element.

Radiant or infrared garage heater

Radiant heat is heat from the sun and it travels in a straight line. This kind of heat warms the object directly unlike the fan-forced heat that warms the air.

Radiant heat has one limitation. You need to be in direct contact with it for you to feel its warmth. This limitation makes radiant heater garage less popular.

Diesel, kerosene or natural gas garage heater

They use fuel in place of electricity. They are perfect if you have a large garage because they produce lots of heat.

Most of these diesel garage heaters are portable and you can move with them anyplace that you want.

However, extreme care is needed when you decide to purchase one of them, because they can be dangerous in an enclosed space. Any leak coming from a diesel can lead to accidents.

Heating capabilities

The heat output you want will depend on the size of the garage. Small garage can be served best by an infrared heater, because all you need is for you to be in direct contact with the heater. They heat objects which is you instead of the air.

British thermal unit (BTU) is used to measure the heat output that heater gives out. If you have a large garage, then consider investing in a heater that has higher watts and BTU. 4000 to 5000 BTU is the perfect range for large garage.

A 1.5kw fan forced heater is the perfect heat output for small garage.

Portable or fixed garage

Do you want a heater that is portable or not? Your choice here will depend on the kind of fuel you choose.

For instance, a diesel heater garage will need refilling from time to time. You have to consider that. Are you comfortable moving it out away.

If you don't want something portable, then you will need to have a fixed garage. The benefit of fixed garage is that you will always be safe wherever you stand.

With portable garage heaters, you have to worry about the possibility of knocking it over or someone else or even your pet.

If you travel or move a lot from workstation to another, you will need a portable garage heater.

Garage heater's safety features

Garage heaters are powerful and dangerous, choose a heater that has safety features such as tip over switch, overheat protection and cool to touch. These features prevent accident from happening 80% of the time.

Which Garage Heater Is Best? Propane, Electric or Natural Gas

I don’t want you to make the same mistake first time buyers make. For most people, they would want to compare these 3 fuel options on the basis of price.

When you compare on the basis of price, you won't get the value out of it. And you will be on the market again, looking for another set of heater, which is expensive on the long term.

I want to compare the three garage heaters on the basis of value that you or the benefit that you stand to gain.

The price should come in the end, because it is not that really important if you put value in place of dollars.

Okay that brings us to the first garage heater....

Electric garage heaters

You will enjoy the convenience that they have. All you need is an electric outlet. They are simple to install. They are also the types of heaters that are least dangerous compared to other types of heaters.

Electric garage heaters have lots of safety features in them such the auto-shut system.

When to come to maintenance, there is little to none. Even if you had a chance to do maintenance, it will be replacing some parts, which can be 2 or 3 years from the time of purchase.

You are better of going with an electric garage heater if the three types of heater are not available in your place or the area where you live.

How about the heat output and the price?

You have to know that electric garage heaters have a standard voltage capacity. That explains why they don't give out much heat.

Three options apply if you need an electric garage heater:

  • Use electric garage heater if you have a small garage
  • Use electric garage heater if you prefer little maintenance.
  • Use electric garage heater if you can't afford other fuel options.

Natural gas and propane gas

I have decided to combine them both, because they all use gas.

Natural gas would be perfect for you in place that you can't find propane. Or propane is expensive in your location.

Natural and propane gas are best used if you have large garage. That is because they provided heat that is 5 to 10 times stronger than the electric garage heaters.

They are portable. If you are the kind of person who moves from station to station, then either natural or propane garage heater will suit you.

But you need to take caution when you are using them. You need to make sure that they are no leakages or loose connection that can lead to fire.

You will need to monitor the amount of fuel that you have on a regular basis so that you don’t run out.

There is some maintenance involved when it comes to fuel refill and you will need the services of a plumber to help you install a gas line, in case you don't have.

The initial purchase of propane gas is expensive. But what I like about is that, it provides more heat in the garage.

Choose propane garage heater in three situations:

  • You have a large garage.
  • You need more heat in your garage.
  • You move around a lot from workstation to another helping your clients. No need to worry about the client having an outlet.

Safety Tips on Heaters for Garage

A heater can increase the comfort and versality in your garage, but it is easy to forget that it can be dangerous.

In fact, most people realize this after they have had an accident. Most accident that occurs in the garage happens as a result of negligence.

Here are some of the safety tips that you need to embrace when you have a heater.

Proper ventilation

Your garage needs to be ventilated. There is must be air flowing freely inside and outside.

A poorly ventilated garage can cause havoc especially if you have propane or natural gas garage heaters. Any leakage, can lead you to fire break out.


If you have a propane garage heater, you will need to check it from time to time.

You need to inspect for any loose connection or leaks. You need to make sure that there is enough gas in the tank.

It is so easy to run out gas and you may know it if it is too late.

Safety features

Any heater that you buy, makes] sure that it has safety features. Here is a breakdown of some of them.

  • Tip over switch: Time and again, you may knock on your heater. This feature makes sure that the heater is turned off before it even gets in the neighborhood of 30 degrees angle.
  • Overheat protection: When the desired temperature is reached the heater is supposed to shut down automatically. That is the purpose of the overheat protection.
  • Cool to touch: Kids and pets are vulnerable; they can touch the heater any time. Look for a heater that has a cool to touch feature, it will saves you lots of trouble.

General tips

  • Never leave the heater unattended to, always make sure that it is turned off whenever you want to leave your workspace.
  • A garage shouldn't miss fire extinguisher especially if you have a big garage and you are using propane heaters.
  • Before you do any general cleaning for your garage, make sure that you disconnect the heater from the fuel supply.
  • The heater needs to be on a stable secure surface or ground prevents the risk of being knocked over.
  • Flammable substances such as debris saw dust should not come into contact with a heater, they can lead to fire.

Follow the safety manual

Easier said than done, most people will read the manual, and then ignore the instruction. On the manual, you will find the amount of space you need to give the heater the clearance that it needs.

Best Way to Heat a Detached Garage

Look into any forum any you will see a debate about detached garage going on.

There is something that is not said and I want to spit it here. The issue of heating detached garages is the same with the shops. Here is how to deal with issues properly.

Check out the local ordinances

You need to know the area code before you place a heating unit in your detached garages. They are some things that the local area doesn’t allow and this creates a problem.

For instance, during certain weather conditions, there must be no wood fires and it can be difficult for you to light your propane garage heaters.

You need to have a permit from them to install any kind of heating unit. An inspector will also come to your garage to inspect if you meet the clearance requirement rules.

You need insurance

If you are going to install heating unit in your detached garage you will need an insurance cover for it. Insurance issues can be tackled first by calling an agent.

Detached garage and shops don't fall in the same category as the home insurance; you will need to consult an agent for these so that you can be specific.

Choice of heat

After you have had a green light check on this two core areas: local ordinance and insurance, then you are fee to use the heating unit of your choice. That is way you can heat a detached garage or your own shop.

Final verdict

I wanted to make the review in-depth and long to achieve two things.

  • Help you select the best garage heater.
  • Give you more information about the garage heater so that you know what you are dealing before you even purchase. That is why I included little bit of information like the cost of operation.

And my hope is that I have done my best to highlight as many possible heating options as possible, so that you have an informed decision.

There is no perfect product that is why for every product I included the limitation.
