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!

    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,

    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?
