If you’re thinking about heating your garage with one of the dozens of different models of electric garage heaters, 120 V may not be enough for you. Yet most of us don’t have 220 V lines in our garages. So deciding whether a 120 V model is sufficient depends on how well the garage is insulated, how much heat you want to produce, and how warm you’re trying to keep the space. Depending on those parameters, the 120 V electric garage heater has some pros and cons.
Electric Garage Heater 120V
Before we get into those things, however, let’s calculate how much heat the average 120 V unit will produce. We do that by using the following formula, assuming a 15 amp (1.8kw) circuit:
1.8KW x 3412 = 6141BTUH
Unfortunately, at that rate, it would require at least several heaters to keep your garage comfortably warm on cold winter days. Even a single 120 V heater running 24/7 will barely keep the temperature above the freezing mark on a day when the outside temperature is 20°F or lower. So where do we go from here?
If your goal in using electric garage heaters of 120 V is simply to keep the air temperature warm enough to start your car in the morning, you’re golden. For some people who live in extremely cold environments, they would prefer to use this type of heater instead of installing a block heater in their vehicles. For the purposes of this discussion, whether or not that is wise is irrelevant. The point is, the 120 V heater will do a sufficient job if it’s placed near the front of the car.
Likewise, if your heating goals consist of simply keeping the garage above freezing or warming up your work area, a single 120 V heater should be sufficient. You just have to make sure that you allow it to run for enough time in advance so that the work area is warm enough when you’re ready to begin. While you certainly won’t be able to work on your car in shorts and a T-shirt, you will stay warm enough to work comfortably.
Heating your garage so that it’s as comfortable as your house probably will not be practical with electric garage heaters, 120 V or otherwise. Perhaps with a 220 V heater and the proper insulation you may get close, but portable space heaters are designed specifically to heat small spaces for temporary periods of time. For comfortable heating on a permanent basis, you’re better off installing a standard gas or electric furnace just like you have in your home.
That said, sometimes local zoning laws make installing a regular furnace cost prohibitive. In some cases, it may not even be allowed. It’s then that you might consider several electric garage heaters placed strategically around the space and hard-wired to the garage’s electrical system. In a scenario like this, you’re much more likely to keep the garage warm for longer periods of time. And by hard wiring the units to the electoral system you reduce the chance of fire.
Protecting against fire is important for both safety and legal reasons. Obviously, a fire is dangerous to you and your family even if it occurs in the garage. From a legal standpoint, a fire could lead to charges of zoning violations, endangering the welfare of a child, and other things depending on the jurisdiction in which you live. So making sure all electric garage heaters are used safely all times is important.
In summary, if you’re thinking of heating your garage with electric garage heaters of 120 V, be sure to compare all the pros and cons in order to make a wise decision.
Your garage is the place where your car spends the night, where memories are stored and where you relax while pottering around with some woodwork or another hobby; however, when the garage is cold you are unable to enjoy the space and it’s unlikely that you’ll spend time there doing your beloved hobby, so this is where electric garage heaters 220v come into play.
