Best Garage Heater Reviews & Easy Guide for Beginners

Garages are usually meant for the cars, and thus they’re not the coziest place to be in, especially in low temperature. They’re constructed from brick and timber only, and often without any kind of insulation to keep them warm. However, there are some like myself who are interested to find other prospects as well – a garage can be an efficient workplace and a perfect little secluded world to be in. Remember how Nirvana was born? Or perhaps Apple?

But usually, at a low temperature, you will not be encouraged to use your garage. So, if you have to prevent pipes and equipment from freezing, keep cars relatively warm overnight and practice with your garage band or complete workshop projects during the most frigid times, a garage heater might come in handy. Winter is coming, and maybe it would be clever to invest in one.

Different heaters can heat different sized spaces, so it is vital that you measure up your garage and ensure that the heater that you choose is adequate for the size of your garage. If you choose a heater that is made for a larger space than your garage, you may find that it is not very energy efficient, whilst a garage heater intended for a smaller space will leave your garage feeling cold.

Before buying a garage heater, a number of factors have to be considered so as to ensure you get a heater that fits your home’s specific needs. Here are some tips:

Learn about the Heater’s Range

Heat range is a measure of the space your heater can warm up, measured in British Thermal Units (BTUs) for gas heaters and watts in electric heaters. You want the heater range to be appropriate for the size of your space, so that your garage can be warmed as efficiently as possible.

Consider the Maintenance

Both electric and gas heaters require maintenance, though at different levels. For electric garage heaters, wiping with a damp cloth and vacuuming is all it takes to maintain the unit. For gas heaters, the air vents need to be unblocked, dirt vacuumed out of the motor, and the burner cleaned with a wire brush.

Ensure the Heater is Safe

Like all things that involve gas or electricity, the safety of your heater should be ensured. Buy a heater with discharge grills and a fireproof intake. Be sure to keep heaters away from flammable objects in the garage, and clean them often. Additionally, check for an automatic shut-off, in case you forget to turn the system off.

Heaters come in all sizes and types. You have a variety to choose from different power sources like electric, natural gas, propane, hot water, infrared, wood/coal, wasted oil. As per efficiency, you can very well rely on good old electricity, which may cost a little, but gives in return a 100% efficient heating. But, if there are frequent power shortages in your area, or if you want the heater to go easy on your pockets, there are several other options as well. Coal, shelled corn, or waste oil might be the cheaper alternatives that you're looking for.

The Most Popular Variants:

Electric Garage Heaters

An electric heater efficiently converts electricity into heat to warm your garage. Most devices feature thermostats and gauges that let you easily establish and regulate the temperature. Many electric heaters can be mounted onto a garage wall or ceiling, and most include a thorough manual to let you quickly install the unit yourself. How much power your heater needs depends on your garage’s size, its insulation and the temperature you want.

These heaters don't cost much, apart from the power usage.

Natural Gas Garage Heaters

With a natural gas garage heater, a pilot igniter uses gas flowing through a valve to create a flame inside a heat exchanger. A fan then circulates the warm air.

Natural gas heaters can rapidly turn blazing hot to heat large spaces, they do not need electricity. You must connect the device to your natural gas line. Most products include detailed instructions to properly install the unit and connect it to an efficient ventilation system to remove harmful combustion chemicals from your garage.

Propane Gas Heater

A third option is a propane gas heater. It creates a flame inside a heat exchanger, and a fan sends warm air into your garage. Propane heaters are very powerful and highly effective. Because propane gas is extremely flammable, you should ensure that the heater is out of the reach of children and far from flammable materials. You may want to hire a professional to install your unit.

Gas Infrared Heaters

Gas infrared heaters, also known as radiant tube heaters or infrared tube heaters, are the most efficient way to warm people and objects in large open areas with high ceilings, poor insulation and overhead doors. Infrared technology heats people and objects, not the air. Gas infrared heaters can consume 50% less fuel than fan forced heater systems. The upper half of the space is not heated and occupants underneath the radiant heater feel immediate warmth. This allows thermostats to be kept at lower set point temperatures. Infrared heaters are factory built for use with natural gas or propane.

Hydronic Unit Heaters

Hydronic unit heaters are found in commercial and industrial buildings where central hot water and steam boilers are used for heating. Hot water unit heaters are designed to produce a lot of heat fast. Multiple hydronic unit heaters are typically installed in large facilities. Each hydronic unit heater is controlled independently with a wall mounted thermostat. Many heat exchanger types are available to meet the most demanding applications. Hydronic unit heaters are available in horizontal air flow and vertical airflow designs, with several fan styles with varying airflow rates.

Choosing the perfect heater is not easy. Like the wand, rather it chooses you, depending on the space and insulation of your garage, which fuel you are using, and how cold the temperature is.

Now, there are plenty of machines in the market. You may act accordingly on your choices and preferences. For your help, I have prepared a list of the best garage heaters. Feel free to scroll down and see.
