Electric Heat for a Cold Garage
Electrical Question: What is the best way to heat my cold garage?

I use my garage as an art studio and am trying to determine the effective and cost efficient way to heat the garage during the winter, (it gets down to the low 30’s and even 20s here).

The problem with the first option is that all outlets are standard 120 volt.

Thanks for any help!

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.

    We have a cold garage that only has 220 volt wiring. So we purchased heating units with fans to boost the room temp. The only thing is, this didn’t heat it to a warm degree and it threw the circuit breaker out. What would be our best bet to use?

  2. Dave Rongey says:

    Hi Barb,
    The type of electric heat that will be installed to heat a cold garage will depend on more information about the garage, including but not limited to the following:
    Are the garage has the walls and ceiling finished off with sheet rock? if so then baseboard heaters may be an option.
    If the walls and ceiling are not covered with sheet rock or the garage is drafty then you may consider portable heater units that produce direct radiant heat that is either infra red or a quartz tube type of heater, however keep in mind that portable heaters should have built in safety switches that turn off the unit automatically if the heating unit tips or falls over.
    The type of heating units that can safely be used in the garage will also depend on what is stored in the garage, such as flammable materials and substances which can pose a potential fire hazard or harmful condition.
    The type and size electric circuit to the garage must be clearly identified to fully understand the size of heater that can be installed, however as mentioned above, all of the other factors about the garage must be considered as well.
    I hope this helps,
