What Are Some Advantages of a 240V Heater for a Garage?

Temperatures fall significantly in winter, and the movement is restricted. People try to stay indoors. To make the most of their time, people have different activities to keep them hooked. A garage is a place that can be used to do several tasks, like for storage purposes or executing a DIY project. 

The following are some of the main advantages that a 240V Electric Garage Heater gives you.

Adjustable Thermostat

Throughout the whole day, the temperate keeps changing from being cozy during the day to ice-cold in the night. To tackle this, you need an adjustable thermostat. It will help you to set the temperature of your room in a desirable setting. Over the months, the weather gradually changes, and the same amount of heat won’t be enough to keep you warm. Thus, with an adjustable thermostat, you can change the settings according to the usage.

Overheat Protection

A garage is a place that is not occupied all the time. Most of your time is not spent there, and you only go there for a specific purpose. So, you need to be careful when a unit is running in your absence. This is why an overheating protection feature is available in the top units. Most new garage heaters are integrated with overheat protection to prevent any mishap.

Wall or Ceiling Mounted

Keeping a heater indoors always has its risks. Any accidental contact can cause an unfortunate incident. To avoid this, these units are mounted on a wall or the ceiling. This keeps them out of reach and makes them safer than portable or other types of models.

Can You Really Find a Quality 240V Electric Garage Heater That’s Affordable?

The first thing that comes to anyone’s mind is the price of a product. Is it affordable? Is it too expensive? These are some of the more common thoughts. But the thing that matters most is the quality of a unit. An electric garage heater is something you’ll want to have for a long period. This is why quality should be the top priority. 

Most modern affordable electric units are equipped with some of the top features and have a fairly long-lasting design. They are meant to do the job efficiently and provide great value for money.

When Is It Time to Replace My Garage Heater?

While buying a heater for your garage, you would want something that will last longer, requires minimal maintenance, and delivers the best quality. On average, a decent-quality product will last for eight to ten years. 

Several signs can help you identify if something is wrong with your heater. Then you can get it checked by a professional and decide whether to get it repaired or replaced. The first and primary sign is a sudden decline in performance. Additionally, any unusual noises from the unit are also a sign that it should be taken to get checked.

What Do I Need to Know Before Buying a 240V Electric Garage Heater?

Looking for an electric garage heater can get a little tricky due to the various aspects involved that ensure that a product is top-notch. Different people have different requirements, depending on their usage. The following are some of the basic factors that you should consider before making a purchase decision.

Size

The first and most important factor is the size of a heater. It all depends on the size of your garage, measured in square foot. Meanwhile, the power capacity of a unit is measured in British Thermal Unit (BTU). On average, 20-40 BTUs are required to warm each square foot area of a well-insulated room.

Mounting Options

While choosing a heater, you must have a location in your head where it will be installed. Most modern products are mounted on walls or the ceiling. This depends on which part of the garage you spend the most time in and where the heat distribution will be even. A wall bracket is generally required, which is mostly now included with the product.

Safety Features

With increasing technological advancements, more and more safety features are being introduced. The most important safety features include overheating protection, tip-over protection, and cool-touch construction. Make sure your chosen unit has some, if not all, of these. 

How to Wire a 240V Electric Garage Heater

If you are installing a unit for the first time, here are some key steps and tips to remember:

  1. Make sure the unit you are installing is suitable for the square feet area of your garage. Usually, 240 volts or 17000 BTU are ideal for such spaces. 

  2. Unscrew the fitting where you can get access to the wire connections. You will need ten gauge wire and two shielded wires. 

  3. Always remember to tape the wire with the current with electrical tape. 

  4. Before connecting the wires, install the plate or the unscrewed cover that you earlier unscrewed to access inner wirings. 

  5. With 240-volt units, you do not have to worry about polarity. Using wire nuts, you now have to connect wires of the corresponding color. So the black wire will be connected with the second black wire. The same will be done with the white wires. 

  6. To use the wire nut, simply hold two wires together and twist the nut over them clockwise until they are tight and secure. 

  7. When screwing the plate back in position, make sure the wires don’t jumble up and block the fan on the inside of the unit.

If you need further help with the installation and need a visual aid, refer to the video given below. 

Conclusion

In conclusion, after an in-depth analysis of the top-quality 240V garage heaters and what elements make the best products, you now know how to choose an ideal unit that will efficiently heat your garage.

Just remember to don’t go after the premium features; rather, select what will meet your requirements. Expensive features don’t always mean high performance. Sometimes, moderately priced units can do the job equally well.
