The Dr. Heater DR966 was the best 240v heater out of all the electric garage heaters I could find. Not only is it extremely affordable, but it’s also got the features to boot.

You’ll be able to choose between 3000 or 6000 watts depending on how hot you want it. 5 adjustable louvers are included to ensure the air flows in the direction you need it to.

The large 8″ fan provides maximum airflow with minimum noise to distribute the air evenly throughout your garage. Mount it easily on your wall or ceiling with the bracket included.

Purchasers were stating that their 30×30 workshops were easily heated by Dr. Heater DR966. Not only that, they noticed that their electric bill didn’t go up wildly with sporadic use. Be careful though, if left on all day it will use up quite a bit of electricity.

Another thing to watch out for in purchasing an amp breaker that won’t trip from use. You’ll want to buy one that’s 35 or higher to avoid having any issues with the breaker tripping.

All in all, for such a great deal, it was hard to find any fault with this product. This heater was one of the best 240 electric garage heaters I could find!

1) Are electric garage heaters expensive to run?

Depending on where you live and how much your electricity costs, running garage heaters can be expensive. You’ll need to calculate the cost of electricity where you live and how much your electric garage heater will be spending.

Gas heaters are going to be less expensive than electric by around 20%. Be mindful of how long you keep your heater on, you shouldn’t need to keep it on that long unless you’re staying in the garage for long periods. Not that there is anything wrong with that!

2) How do you wire a 240v garage heater?

I’m not a qualified electrician nor will I pretend to be. If you aren’t aware of how to properly wire your heater, please call a professional. 240 volts is enough to kill, always take the necessary safety precautions to protect yourself.

I know that I can’t stop everyone, here is a great video that goes into great detail about how to wire a 240v electric garage heater.

3) Can a 240v heater run on 120v?

I wouldn’t take any risks when it comes to plugging in something where it doesn’t belong. The heater will likely fail to operate and you’re putting yourself and your heater at risk.

4) Is a 240v heater more efficient than 120v?

Not necessarily. 240v uses half the amps as 120v, but that doesn’t mean that your electric bill will be any less. The wattage is what will be the determining factor when it comes time to pay your bills.

5) What size electric heater do I need for my garage?

The rule of thumb is 10 watts for every square foot. A typical 2 car garage is 400 sq. ft so you should aim for roughly 4000~ watts.

Shoot for more than you think you need without an insulated garage. You’d be better off insulating your garage before buying an electric heater to save in the long run.

6) Should I get an infrared heater over a 240v garage heater?

If you do a lot of woodworking in your garage, you may find that a forced air heater will pick up dust around your garage/workshop. If you want to avoid this, you may find that a 120v heater may do you better than the best 240v electric heater.

7) How many BTUs do I need for an electric garage heater?

For a two-car garage, you’re going to want a 40,000 BTU to 60,000 BTU heater. If your garage isn’t insulated, you may want to insulate it first before you go ahead and invest in the best electric garage heater.

8) Can I heat an uninsulated garage?

I think that you may be able to get away with bringing up the temperature a bit even in an uninsulated garage with the right heater. Now, that doesn’t mean you shouldn’t invest in insulation. Before you purchase the best 240 electric garage heater, I would focus first on ensuring the hot air stays in your garage by insulating your garage as well as you can.


We learned a lot today about electric heaters. You can keep your garage warm without spending a ton of money with a little know-how. You’ll be thankful when it’s next winter and your 240v electric garage heater is warming you up. In my opinion, 240v heaters are one of the best ways to heat a garage.
