Are 120v Heaters Good Enough For Your Garage?

If you’ve got a car garage of small size or not bigger than 30 x 30 feet, a 120v heater would be perfect.

However, if you have a reasonably big garage with an area of about 30 x 30 feet or bigger, go for a higher-voltage 220v heater. That’s especially true if the area is poorly insulated.

Since 220v garage heaters generate a large amount of heat, therefore, they’re ideal for larger commercial applications. You’ve to be careful not to use them if you’ve got a small-to-medium-sized garage; in this case, the potential and most viable option would be a 120v garage heater.

Besides, you need to make sure how many power outlets your garage has. This is important since a 120v heater can draw about 20-amps; anything more than that can result in damage to the power breaker and can pose a risk to your safety.

If the garage deals with more amperes or heavy load, you should check whether the number of circuit breakers it has. If there’s just one breaker in your garage, it’s wise to call the electrician!


Types Of 120V Electric Garage Heaters

The 120-volts electric heaters are available in various types. Here’re a few most widely used garage heater types:

Infrared Garage Heaters

This type operates by heating or warming up the indoor air and the nearby objects. This garage heater is also considered the most energy-efficient.

Even after turned off for quite some time, the garage remains heated, saving you money. This heater functions by emitting infrared rays, similar to infrared light that comes from the Sun.

Electric Garage Fan Heaters

These electric heater types are quite popular among US households for one good reason: they deliver high performance at an affordable rate.

Also known as a blow heater, it uses the fan to pass the air across the heating element. As a result, the air gets heated and circulated in the garage.

Although this type of heater comes with enhanced efficiency and low-cost, it makes high noise, which can be frustrating. However, you can overcome this disadvantage by resorting to more advanced technology.

Under-Floor Electric Garage Heaters

The under-floor electric heating system involves several power lines within or under the garage floor to heat it.

Though these heaters are expensive to install, once in place, they have the same amount of running expense as other products. Plus, they’re highly efficient at warming up the garage space.

How To Choose A 120V Electric Garage Heater

Electric heaters can be an excellent source for heating or warming up your garage if you select right. Here’re a few features to consider before making a purchase.

Size

Here’s a quick fact: choosing a small-size heater for larger garages or a large-size garage heater for tight areas is inappropriate. It won’t give you the heating results you desire.

Here’s why:

In case you’ve picked a larger heater, and the garage is small, it means you’re wasting energy. On the other hand, if you’ve got a small heater and the garage is large, you wouldn’t get enough heat output. In both cases, you aren’t getting what you need!

Therefore, it’s essential to check the size of your garage space before buying. Watch this video to get quick know-how about how you can calculate the right size for your garage.

Efficiency

As far as the efficiency of the electric garage heater is concerned, you need to make sure its thermostat is in excellent condition. You should also ensure the electric heater provides the heat output it claims; otherwise, it would simply be a waste of money.

You can evaluate the efficiency of the product you intend to purchase by seeing the customer’s feedback on popular sites like Amazon.

Cost To Performance Ratio

Improved performance always comes with enhanced, premium features; in other words, the more features a heater has, the more it’ll cost.

However, premium garage heaters provide comfort for hours even when switched off. Moreover, they do that with higher efficiency and consistency. Nonetheless, low-cost electric heaters can provide good heating if the garage is small.

You can go through various customer feedbacks for low-cost garage heaters, and if the product you have decided to purchase carries positive feedback, go for it!


FAQs

Where Can I Put a Garage Heater?
