How to choose the best electric garage heater 120v?

It is possible to heat or warm your garage with electric heaters if you select the right ones. To help you choose the right product, here are a few features to consider.

1. Size

It’s inappropriate to choose a small-sized garage heater for large garages or a large-sized garage heater for tight garages. It won’t give you the heating results you want. If the garage is small and you have chosen a large heater, you will waste energy. Alternatively, if you have a small heater and your garage is large, you wouldn’t get enough heat. You’re not getting what you need in both cases!

2. Efficiency

Make sure the thermostat on the electric garage heater is in excellent condition in order to maximize its efficiency. Moreover, it is important to make sure that the electric heater produces the heat output it claims; otherwise, it would be a waste of money. Popular sites like Amazon will let you know how effective a product is based on customer feedback.

3. Cost To Performance Ratio

Enhanced, premium features are always associated with improved performance; the more features a heater has, the more it will cost. Although premium garage heaters can be switched off, they still provide comfort for hours afterward. Furthermore, they do so with greater efficiency and consistency. However, if the garage is small, low-cost electric heaters can be effective.

When purchasing low-cost garage heaters, you can read various customer reviews and if the product carries positive reviews, then purchase it!

4. Adjustable Thermostat

It is necessary to use a garage heater with a built-in adjustable thermostat if you want it to monitor the ambient temperature and turn on or off when the temperature is too high or too low. It allows you to set the ideal temperature for the garage and the heater will automatically begin heating once the temperature is reached. The auto-on and auto-off feature makes it perfect for colder climates that may require 24-hour heating. These features help your garage stay at the right temperature without wasting energy.

5. Maintenance

For garage heaters to remain efficient, they must be maintained like any other heating or cooling appliance. Heaters that are lightweight are less expensive, but they tend to last less long than those that are more durable. As long as you don’t mind replacing your heater every couple of years, you can get enough heat without much maintenance.

If you want your electric garage heater to last longer, you have to clean it regularly, inspect the power inlets for cracks, and test the heat outputs as often as necessary. Rather than having to replace several lightweight heaters on a regular basis, these more expensive heaters may end up costing less over time.

6. Safety Features

If electric garage heaters aren’t installed, set up, and used properly, they can be dangerous. Safety features, including tip-over mechanisms, overheating protection, and cool-touch features, have been added by many manufacturers to make the products as accident-proof as possible.

  • Tip-over mechanisms they’re designed to keep electric garage heaters from falling over, especially when placed in busy workshops, small garages, or homes with small children. In the event that the heater is knocked over, this mechanism automatically shuts it down to prevent damage.
  • Overheating protection the heater has a useful feature that comes in handy on days when the ambient temperature fluctuates by several degrees, causing it to overheat. To prevent external damage to your garage as well as internal damage to the heater, the overheating protection shuts off the heater when the temperature rises.
  • Cool-touch features in garage heaters that are wall-mounted or portable, heat shields are most often used because they are often placed in places where children and adults can come into contact with the heater’s sides. It is possible to burn yourself when you touch or grab the outside shell of a heater without injuring yourself. Heaters without this safety feature can cause a severe burn if not installed correctly.

Frequently Asked Questions related to the best electric garage heater 120v.

Where Can I Put a Garage Heater?

Your heater’s type largely determines where it should be placed. The device should, however, be placed near your workspace. Furthermore, it must be 73 inches above the finish floor and away from any combustible materials.

Is An Electric Heater Costly To Run?

The reality is that electric garage heaters are not as costly to run as many people believe. These units have the same running costs as other heaters, if not less, when considering their lifespan, installation, and maintenance requirements. On average, you’ll spend about 10-15 cents per hour on them.

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

There is no way to tell whether the 120 voltage of a garage heater will be enough to heat up the garage from the outside since it only indicates where the plug should go. It is important to determine how much heat a heater can produce at an optimum price.

It is possible to heat a small room with a heater of 1500W and 5000 BTU, for example. If you wish to heat a medium-sized room, you should consider a 2500W heater. BTUs are a measure of how much heat a heater can produce.

Again, many of us make the mistake of thinking that the wattage of a heater indicates how much heat it can produce. In its simplest form, wattage refers to how much electricity the heater needs to function efficiently. It is possible to run a 1500W heater on a 12.5amp circuit with a 120V supply.
Measuring the size of your garage will help you determine which garage heater is right for you. Multiply the area by 20 to determine how many BTUs are required to heat the space sufficiently. To complete the warm atmosphere, you can buy any of the above 120V garage heaters.

How to Wire A 120V Electric Garage Heater?

There is no doubt that wiring the heater makes anyone freak out. It is, however, possible to save yourself the hassle by hiring a professional electrician. Alternatively, you can follow our tried-and-true method. Here’s how to wire a 120V electric garage heater.

Wiring the Garage Heater
1. First, attach the ½ flexible metal conduit via the knockout hole on the junction box with the first FMC connector. Once the metal conduit is attached to the heater, attach the other end using the second FMC connector.

2. From the end of the cable at the heater, remove 6 inches of sheathing and place it in the junction box. You will need to pull through the conduit 2 pieces of 10 AWG black wire and 1 piece of 10 AWG green wire.

3. Remove one inch from the five wires at the junction of the ceiling after pulling them. In order to connect the black wires, they must be twisted together and capped with wire nuts. In addition, you will need to color all the wires in accordance with local regulations.

4. The black wires and the remaining wires should be twisted gradually and capped with wire nuts. The junction box should then be grounded and the twisted ground wires attached to it. After that, cover the box.

5. At this point, you will see 3 wires connected to the heater junction. It is recommended that you strip 1 inch of insulation from them. Therefore, the black heater wire should be connected to the black supply wire. Make sure both ground wires are connected simultaneously.

6. Then, cover the junction box with cautious care by using wire nuts to cap all of the joints. You can now feel the warm air once the circuit breaker is turned on and the heater is switched on.
