What to Look for in an Electric Garage Heater

Here are some factors to consider while investing an electric heater for your garage:

Garage size

The best way to heat a garage in winter is obviously installing a heater. Probably the easiest way! Before purchasing an electric garage heater, you need to know how much area you are planning to control the heat. The selection of which type of garage heater will depend on the size of the garage. 120V electric garage heaters aren’t ideal for home garages over 160 sq. ft, which means you can’t use electric heaters in a large area, they are only compatible with small size garages. So, you need to measure your garage size before purchasing an electric garage heater.

Safety options

You may notice Electric heaters are much popular among customers. Ever wonder why? Due to the advancement of technology, electric heaters are coming with updated safety features. Overheat mechanism, cool-touch technology, mechanism of tip over, and many more are a few of them. But remember this: Make sure; your selected electric heater has enough safety options to keep you safe from any unwanted situation.

Cost

You can’t depend on the price only while purchasing the best electric heater. You need to know your requirements. And you can narrow down your choices depending on conditions.

And know the coolest part? You should not break the bank and select the affordably priced heater. The good news is; the majority of the 120v garage heaters in our top 10 are coming at a reasonable price with high-quality features. So, choose wisely and don’t eliminate the best one for saving few bucks.

Maintenance

Like every other device, the best electric garage heaters also require maintenance. You should look for an electric heater that is straightforward to clean and can be reassembled again easily after cleaning.

Is It Enough to Have a 120V Electric Garage Heater?

The 120 voltage of a garage heater indicates the outlet to connect the plug, and it doesn’t reflect whether it is enough or not to heat up a garage

What matters is that how much heat a heater can produce at an optimum cost.

For example, a heater of 1500W with 5000 BTUs can heat up a small room. Whereas, if you want to heat a medium-sized room, you should go for a 2500W heater.

In short, the higher the BTUs, the more a heater can produce heat.

Again, many of us get it wrong, thinking that the wattage of a heater means the capacity of producing heat. Rather, wattage is the amount of electricity needed to run the heater efficiently. A 1500W heater of 120V can easily run on a 12.5amp circuit.

For assuring which garage heater is enough, measure the area of your space. Then multiply the area by 20 to find out the BTUs needed to heat up the space sufficiently. Finally, buy any of the above 120V garage heaters to get enough warm ambience.

How to Wire A 120V Electric Garage Heater?

Undoubtedly wiring the heater makes anyone freak out. However, you can either call a professional electrician to save you the hassle. Or do it yourself by following our simple tried-and-true method. So, let’s get started to wire the 120V electric garage heater.

Wiring the Garage Heater

Start by using the first FMC connector to attach the ½ flexible metal conduit into the junction box via the knockout hole. Then, use the second FMC connector to attach the other end of the metal conduit to the junction box of the heater.

Now, from the end of the cable at the heater, remove 6-inch of sheathing and put them into the junction box. After that, you will need to pull out 2 pieces of 10 AWG black wire and 1 piece of 10 AWG green wire through the conduit.

After pulling the wires, slice 1 inch from the 5 wires at the ceiling junction. The black wires must be twisted in one piece and cap them with a wire nut. Plus, you will have to color all the wires so that they match the local codes and ordinances.

Gradually, twist the black wires along with the remaining wires and cap them with a wire nut. Then, ground the junction box and attach the twisted ground wires to the box. Then, cover the box.

From here on, you will see 3 wires in the heater junction. Strip 1 inch of insulation from them. Hence, connect the black heater wire to the Black supply wire. Connect the two ground wires at the same time.

Finally, use wire nuts to cap all the joints, replace the junction box and cautiously cover the box.

At last, turn on the circuit breaker and switch the heater to feel the long waited warm air.

Wrapping It Up!

So, have you picked the best electric garage heater 120V yet? We’re sure you did because these heaters are not something you see every day, right?
