To start with, let us quickly consider the meaning, types, and benefits of a garage heater. Then, I will also discuss the essential things to look out for before buying a garage heater.

Garage Heater; An Overview

Garage Heater; An Overview

A garage heater is a natural or propane gas unit that provides warmth for car garages of any size during the winter months.

It is a heater that is used to combat cold garages and workshops during the winter months. Also, there are separated combustion models that provide heating for hard-to-heat applications.

Even so, it has a heating capacity that provides warmth for a one-car garage and up to over four cars garage application. Furthermore, it usually comes in a separated combustion model that provides heating for hard-to-heat applications.

More so, it is available in natural or propane gas. However, in the subsequent paragraph, we will consider some garage heater type classifications.

Garage Heater Classification;

Garage Heater Classification;

Although there is no basic rule for classification, however, a garage heater can be classified based on the following types:

  • Heating Technology
  • Mounting Option, and
  • Power Source.

However, I will be stating the types of garage heaters based on these classifications in this article of the “5 best garage heater”.

Heating Technology Types;

There are three types of heaters in this category, and they are:

Radiant Garage Heater

Radiant heaters are also known as infrared heaters. They radiate infrared light that heats the objects it ‘shines on.’

Also, they produce different heating levels around your garage and leave the air as cold as it was before turning the heater on.

However, their disadvantage is that they do not heat the air and directly heat anything that is not a direct line of sight to the heater’s radiator. Though, objects around the radiator’s shadows may receive some reflected heat from other objects or surfaces.

More so, the infrared light makes the object twice as far away from the radiator as other objects that will only receive one-quarter the amount of radiated energy.

In addition, the radiant garage heater will be more effective than the other options they rely on for circulating air to distribute the heat if the garage front door is often opened.

Convection Garage Heater

Unlike the radiant heater, the convection garage heater heats the air directly and produces a more evenly distributed heating effect throughout the garage.

Theoretically, they use a bit less energy than the forced-air heaters. More so, the air becomes less dense than the surrounding cooler air and floats up toward the ceiling when heated.

Also, they produce less dramatic temperature differences around the garage than those caused by radiators. However, it produces a circulating current of air and is continually driven by temperature differences.

Forced-Air Heaters

These type of heaters blows the heated air through a fan. Also, they heat air directly and blow it around the garage instead of waiting for it to be gently circulated.

More so, they produce more heating effects and tend to work better in more oversized garages with two or more parking spaces by forcing the heated air to move around the garage.

Although, they use slightly more energy than the other types because of the additional work of forcing the heated air to move.

However, you do not have to drag them hard like others for the whole garage to be comfortable because of their ability to distribute the heated air.

Power Source Types;

In this category of garage heater types, there are two types, which are:

Electric

You have nothing to worry about while using this type of garage heater. This is because it is the simplest to install and easy to maintain and operate.

Also, it is recommendable for almost everyone as it is the most environmentally responsible option. However, this depends on your electricity supply.

More so, it is reliable for people connected to the electrical grid. And, they do not cause annoying and dangerous fumes.

Fossil Fuels / Hydrocarbons

Different safety requirements, the complexity of installation, and regulations are essential in this power source.

There are two types of fuel heaters, and they include:

Propane And Kerosene: They are used by portable heaters and are less expensive to buy.

These types of fuel should be avoided if you are sensitive to petrochemical fumes or have a medical respiratory condition.

The reason for the avoidance is because some heaters using them will produce irritating fumes even when working correctly.

Most importantly, do not use fossil-fueled appliances in an enclosed space without adequate ventilation.

Above all, the advantage of these heaters is that they are less expensive and very portable.

Natural Gas: It is the most complicated garage heater. Therefore, if you do not hire a contractor to do the work, you will have local codes to adhere to or some inspections to be done.

However, the rules guiding this installation vary from place to place, but in your interest, contact your local authorities to find out the local requirements before buying a gas-powered garage heater.

The natural gas garage heaters are the most expensive type for professional installation but the cheapest to operate if you already have gas in your home.

Gas-powered appliances are subjected to regulations because they can cause the death of anyone if sub-standard work is done. Even more, carbon monoxide poisoning is one of the significant risks.

Mounting Options

These types of garage heaters are about the method of positioning. And these methods are of three types which are:

  • Portable / Stand
  • Wall Mounted
  • Ceiling.

On this note, we have come to the end of types of garage heaters by classification. However, we will proceed to the factors to consider before picking the top 5 garage heaters.

Garage Heater Buying Guide;

Garage Heater Buying Guide;

This section of the article will discuss the factors you should consider when buying a garage heater.

Choose the correct BTU (British Thermal Unit)

BTU is the energy used to describe the rate at which the temperature can be raised in a specific space. For example, it can be determined by calculating the size and height of your garage ceiling.

However, a new generously sized workshop or a 3-car garage will need 50 000 BTUs for operation.

Noise Level

To avoid buying a heater with annoying sounds after installation, check out the detailed specs of your new garage heater before buying it.

This consideration is to help you get a more comfortable environment without any disturbance of your heater’s sound.

However, if your garage is noisy, you may not need to consider this factor while buying.

Installation Process

It is best to use a portable heater to avoid complicated installation processes. Also, you can buy a portable heater if there will need to bring it outside your home or carry it around.

However, if you plan to invest a lot of time in your garage, you will need to buy a hardwired heater into 220V, 110V, or 240V.

With this, you will have an assurance of a well-functioning heater without the risk of ruining a fuse. Although, it requires the help of a professional electrician for installation.

Fuel Types

As earlier explained, a garage heater has two main fuel sources: natural gas and electricity.

However, your garage can be effectively heated with any of the two, having different benefits. The gas heater is recommendable for small and large spaces up to 4,500 feet.

Even so, the gas heater can be less costly to maintain and operate.

On the other hand, the electric heaters are not so effective in larger spaces and are best for spaces less than 500 feet and below.

This is, however, because they do not use fossil fuels. Consequently, they can easily be relocated and even have high-efficiency ratings.

To determine the best fuel type for your need, you may need to consult an expert.

Garage Size

This involves assessing the heat range of your garage knowing the number of square feet needed to be heated in your garage.

Also, this information should be labeled on your heater, but you may need an installation technician to help in the calculation if it is not.

However, installing an ineffective garage heater is more like a wasted effort and money. Hence, it is important to consider this factor before buying your heater.

Environment Of Your Garage

It would help if you considered the environment of your garage, where you intend to place the heater. Sometimes, the insulation in your walls and window or the doors in your garage may not be adequately sealed.

Thereupon, this will affect the capability of your new garage heater as every garage differs. Hence, you should buy a garage heater with powerful BTUs that the supposed necessary.

Safety

This is always important when considering a new garage heater. Adequate ventilation is needed for a gas-burning heater for a garage set up to run on natural gas.

Also, evaluate what is in your garage and who uses it. Finally, consider the accessibility of children and pets while choosing a heater.

If you work in a dusty place, then an electric garage heater will be good for you as it requires minimal maintenance, unlike the gas heater that needs deeper cleaning to air vents, burner, and motor to remove dust and debris that can cause fire hazards.

Additionally, a ceiling-mounted heater makes the burner out of reach and provides safety to everyone.

Other factors to consider are the features of the garage heater, which are:

  • Mounting brackets.
  • Adjustable thermostat
  • Fans
  • Heating Capabilities
  • Portability, etc.
