Good & Affordable Garage Heater: 2018’s List To Make Your Workspace Worm!

These cold mornings or winter days, perhaps that late night work out, whatever the reason you need to use your garage, a heater is always a great piece of equipment to have around.

The concept behind the garage heater is simple; it’s a stand-alone unit, connected to the electric mains and heats up small spaces quickly. There are also larger units to heat up larger spaces too. This guide is a look at the top 11 garage heaters we tested out of hundreds that applied for a quality check during 2018.

2. TPI Corporation OCH46-120V-SS Quartz Electric Infrared Heater

Quality88%
Durability85%
Practicality 86%
Price86%

Introduction

This is the TPI Infra-Red (IR) heater that uses quartz tubes to generate heat. OK, now that we have the name started out, let look at this properly. IR is just a fancy way of saying heat since all heat is generated in the IR range. Now, this unit produces a lot of directed heat to a small area very efficiently. The reflecting agent is a gold colored anodized aluminum surface. Aluminum is a better conductor of heat since it needs to heat up its entire surface (quantum heating).

Watts: 1,500 to 3,000

BTU/CFM: 5,120BTU

Dimensions: 48” x 5.375” x 6.5”

Overall Impression

This is a bigger unit in comparison to other models, but it does heat up more efficiently. It comes with a minimum 60o angle, which is fine, and it does provide three forms of heat transfer; convection, conduction, and radiation. Pricewise its great value for money.

Choosing the Best Garage Heater for you

To decide which heater, you need you to have to consider three factors:

Size: How big is your garage or room space that needs to be heated?

Energy: What power source do you want to use; Electricity or Gas?

CPH (Cost per hour): What is the estimated cost per hour of using the unit, and will it perform that heating job as you want. This is not the purchase price; it’s the purchase price + the operational costs. This is where you take the purchase price and split it over three years (expected lifetime for depreciation) and add the monthly O/H.

By answering these questions, you will be able to ascertain which unit falls within your budget constraints.

Now, within the category of choice, you have to decide whether you want a wall fixed unit or a portable model. In general, portable models give you more freedom to focus the heat on a specific direction, while the wall mounted heaters are used to heat up general areas.

Let’s take a look at the two different power sources more closely:

Gas powered heaters are more economical to use than electric heaters, and the best versions are the natural gas heaters.

Natural Gas Garage Heaters

These provide clean heating and come in two varieties, a fan forced heater or an infrared tube heater. The fan forced is the better delivery method, but remember both methods are dangerous. Natural gas, when burned, can leave toxic gases, so you need to install a proper exhaust system, and your room should have good ventilation. Another issue with gas heaters is their fire risk.

Electric Garage Heaters

Electric garage heaters are still the most popular choice, mainly due to their easy installation, lack of replacing gas bottles, and being safer and less toxic to the environment. On the other hand, they are more expensive to run, and the higher the wattage, the higher the electricity bill you get every month.

These heaters come in two versions, the radiant and the fan-forced. The fan forced heaters to tend to work faster at dispersing heat over larger areas, while the radiant heater units tend to be more localized, focused and better for heating smaller spaces.

The downside of a fan-forced heater is that it will dry out the room and suck out the air quickly, so you need good ventilation. The downside of a reflective heater is that it works best at close range or in small spaces.

Power Output Levels

BTU (British Thermal Unit) is the preferred power output test for garage heaters, CFM is another option, but CFM only gives you the time it takes to heat a space to the temperature you desire, while BTU gives you the absolute temperature you can reach. Watts are used when an electric heater is a preferred choice. However, Watts is not a heat measurement only a power usage measurement. You still need to know how many BTU’s or Fahrenheit your electric unit will generate at the watts they provide.

250’ garages are best heated with 4,000 to 9,000 BTU; you don’t need more than that.

500’ spaces will need a larger unit, and preferably a gas one that generates 25,000 BTU’s and up.

Safety Issue

Never underestimate the dangers of a heating unit, whether electricity or gas powered. These are one of the main causes of house fires and as such, must be properly maintained and operated.

When installing any heater, make sure the connections are secure and safe. For gas this means no leaks, for electricity, this means closed circuits and no water.

Touch-safe: Make sure your heating element has either a cool touch surface or a wire guard to protect you from touching the heating element by mistake. Remember, the right guard is also hot, so don’t touch that either.

Overheating Protection: One of the biggest issues with heaters is overuse. Sometimes, on very cold days, you will turn the heater on and leave it on even after finishing your work. This can lead to overheating and will either damage the unit or pose a health risk. Find a unit with an overheating safety switch; this means the unit will turn off automatically when the integrated sensor registers pre-set danger levels.

Tip-over Switch or Sensor

The best models today come with a tip over safety switch. This means that when a portable model falls over, the unit will recognize this through an integrated tumbler switch that will turn the unit off.

Heater Settings

The best heater units will come with a heat adjustment setting. The most basic ones will come with a pull cord, this will either turn the heater on and off or go through two or more modes of heat.

The more versatile models will come with adjustable switches that allow you to choose the heat levels, either by increments or by smooth curve adjustable heat levels.

Adjustable Louvres

Certain fans come with adjustable louvers that can direct the flow of heat to a specific location, these are usually found on fan blown heaters and are very useful in smaller confines or on portable models, where you want to control the direction of the heat.

Power Cord and Gas Hose Length

Always make sure that your unit has enough power cord and gas hose length. Electric units only need a power cord, and the fixed ones just need to connect to a main. The portable ones should come with enough length to enable you to position them wherever you want in your room.

Gas models should come with enough hose length to allow you to keep the gas tanks safely secured away from any heat sources.
