How To Choose An Electric Garage Heater With 240V?

Here comes the ultimate question, how to choose an electric garage heater with 240v? There are few factors that play a vital role in choosing an ideal garage heater with 240v. The goal is not always going for the best one, but to avoid the worst one! As you know, a smart purchase would make you happy, but it can make you twice as much devastated if you make the worst purchase! Let’s take a look at some of the most common and pivotal factors to choose a garage heater.

1. Mounting

This can give you a real headache if you do not consider it before buying. No matter what shape your heater comes in or how much it weighs, mounting can be tricky for some heaters. Make sure your heater is easily mountable and it does not take all the space of your ceiling or wall. It wouldn’t be a good investment if your heater costs you additional bucks just for installation.

2. Remote Control

Controlling your heater can give you real trouble, especially when it’s mounted on your ceiling. Make sure your garage heater comes with a remote control feature to avoid any extra hazards. Besides, it can come up in handy in case of an overheating situation.

3. Safety Feature

This is a very serious issue to take into account. There are lots of cases of fire hazards that were allegedly generated by overheating a garage heater. No one wants to buy something that can potentially burn his beloved house down to ashes unless you are that girl we often see in the memes! The newest models are now designed with a special safety feature that would prevent any unwanted fire situation. You should that into account as well before making any purchase.

4. Design/ Size

I know some people would not like it, but size matters, at least while you are buying an electric device! No matter where you’re using this heater, design is always important to consider. A good heater comes with a great design that increases its performance and durability. Additionally, the size of a heater can be decisive given the space it’s going to take. You might take this into account while buying a garage heater.

5. Heating Capabilities

Each heater comes with some specifications that explain the amount of energy it’s going to take and the amount of heating it’s going to provide in the process. Usually, a heater that comes with a 240v is going to cover the same amount of spaces as a heater of 120v. Nevertheless, there are few more things that need not be overlooked such as the amount of amperage. A 240v heater tends to take 50% lesser amperage than a 120v which is decisive given most house has limited amperage. Depending on your requirement and power supply, make the smart buy.

6. Overheat Protection

It’s quite similar to the safety features we talked about. Before you buy a garage heater, make sure it has any of these options built-in. This would make you avoid any kind of accident. Most electric heaters now come with a safety and overheat protection feature, but still, you should make sure before buying.

7. Maintenance

Again, we do not want you to keep spending on your heater once you buy it. Some heater comes with very complex maintenance, however, if you buy a one that is easy to maintain, you would be capable of maintaining it all by yourself. With that said, we recommend you buy a product that would help you avoid any kind of additional expense.

Product Recommendation

Here comes the verdict. Upon researching multiple products and considering their specs and price, we have a solid recommendation for you. You can unhesitantly go for Dr. Heater DR966 Hardwired Heater. Its world-class design and overall specification are undoubtedly the next things you need for this winter.

Electric Heaters vs. Other Heater Types

As we have drawn our final verdict regarding the best 240v garage heater to buy, let’s talk about other types of heaters as well. Other types of heating systems are most commonly Furnace, Boiler, Heat Pump, Gas-fired space heater, Wood burning, and pellet stove, and Fireplace. The electric heating system is certainly the easiest way to warm up your room or basement and it offers a lot more than other means of heating system. But let’s not forget that it has its drawbacks too. Regardless, buying an electric heater is still worth every penny and if you compare it to others, it’s just logical to go for it.

How Much Power Do You Need?

Ok, one of the drawbacks, maybe the most important one, of an electric heater is its consumption of electricity. Obviously, electricity is going to cost you more than a gas or a wood-burning heater, for instance. However, if you know what we are doing before buying an electric heater, we can minimize our cost significantly. That brings the ultimate question, how much power do we need to operate a 240v electric heater compared to the space you need to warm up?

There are few formulas that can help you estimate the required wattages you need based on the type of room you have. The result is not always 100% accurate all the time as room size, orientation, and a number of windows play a vital role here. 

Let’s say your room’s height is 8 feet and the area is 400 sq feet. To estimate the required watts, you can use this formula:

If you have a room with a ceiling higher than 8 feet, you can use the following formula to estimate the required watts.

Let’s say your room is 10 feet high, and the area is 400 sq feet, the required watts would be:
Result: 5000 watts

This result may vary given the fact that some houses have multiple windows or have direct sun exposure. You can adjust the percentage to get an optimum result.

People from North America can convert this result to BTU/hr with the following formula. P (kW) = P (BTU/hr)/ 3412.14 or you can just use Google to convert them, easy-peasy!

You see, it’s really easy nowadays to identify this kind of technical stuff, and it can offer nothing but a great help for your next big purchase.


How does an electric heater transfer heat?

An electric heater converts an electric current into heat. Some of the most common heat transfer mechanisms are convection, conduction, or radiation. This device is designed to take electrical energy as an input source of power. It later converts that energy into thermal energy for heating the air.

What is the voltage of an electric heater?

Voltage is the dedicated electrical circuit that each electric heater requires to function. An electric heater usually comes with multiple voltage options, the most common ones are namely 120 volts and 240 volts. Taking the size of the room or space you want to heat into account, the requirement of this voltage slightly varies. However, a 240 volts heater tends to make the best use of amperage than 120 volts.

Why is a 240-volt heater more efficient than a 120-volt heater?

Although the no notable difference between the efficiency levels of these two types of volts, however, there is a certain term that makes a 240v heater a better choice than a 120v one. It’s about the amperage. Most electric panels of a home is limited by amperage and a 240v heater is more efficient when it comes to taking up the amount of amperage. A 240v heater would take 50% lesser amperage than a 120v which would make room for you to go for other electric appliances for your home.

Can a 240V heater run on 120V?

Of course, it would run, but the level of your performance would drop. While you should know that it’s not a safety risk to use a 240v heater on a 120v electric panel, however, it would fail to provide the adequate heating it’s capable of. Make sure what kind of power supply circuit you have before purchasing a heater.

What is the most efficient electric heat?

If you are talking about the most efficient form of electric heat, I would go with Electric radiators and infrared panels heating system.

While most electric radiators produce 67% of their warmth as convection to heat up a room quickly, the rest of the heat is produced as radiation. This creates a long-lasting background warmth that does not go away even if you make movement from one room to another. This is also known as radiant heat.

Radiant panels, on the other hand, produce 100% radiant heat which works great for home and business. Unlike the electric radiator, it takes a relatively long time to warm up a room from cold. As it turns out, if we compare the efficiency level, an Electric radiator is undoubtedly is better for electric heat. 


So that was it. This complete guideline of the best 240v electric garage heater to buy this winder would be sufficient enough to make the right decision for you. We know choosing the best electric product might come up as overwhelming sometimes, regardless, once you take the right one, all the afford you put through is totally worth it. You may go with the product we have recommended or make your own choice based on the information we have provided here in this article.
