Can A Mini-Split Heat A Garage?

Also called a ductless heat pump, a mini-split uses an outdoor and indoor unit while taking advantage of inverter technology. The outdoor module collects heat, compresses it, and efficiently delivers the collected temperature to the connected indoor space like the garage.

Additionally, a mini-split system can also work well in cooling a room. Certain variants come with air conditioning and heat pump features, allowing users to enjoy these products in hot and cold seasons.

A lot of mini-split systems can maintain efficient functionality in temperatures as low as 10 degrees Fahrenheit. However, users living in regions that experience temperatures below 10 degrees Fahrenheit should opt for a unit heater or wall furnace instead to bring comfortably warm temperatures to their garages.

What Is A Good Temperature For A Garage?

The ideal temperature for a garage depends on how you use the space. For instance, take note of the items inside the garage storage area when thinking about an ideal temperature range.

For example, you’re using the garage to store your car. Lead-acid batteries for vehicles can remain optimal functionality when stored in temperatures between 41 to 113 degrees Fahrenheit.

On the other hand, you might be keeping some power tools in your garage. If so, various battery-operated machines generally use Lithium-Ion (Li-ion), Nickel Cadmium (NiCad), or Nickel Metal Hydride (NiMH) power cells or packs. These units usually need to be in storage areas with temperatures of 32 to 113 degrees Fahrenheit.

Take note that the garage should still be at an ideal temperature range to stick to a dew point. Dew point is the capacity of the air to hold moisture and humidity at 100%. If the temperature in the space drops below the dew point, excess condensation and moisture will begin to form, causing risks of issues like corrosion and mold growth.

Check an online map to see the ideal dew point range for different states. For example, some locations in Wyoming should prevent moisture-related issues in their homes and garages if their spaces are within 30 to 35 degrees Fahrenheit. In comparison, Florida requires a dew point of 60.1 to 65 degrees Fahrenheit.

Moreover, garages used as living spaces should remain comfortable at 64 degrees Fahrenheit.

Take note that some heating systems, such as radiant heaters, may need unique thermostats for efficient controls. Read the following post for more information about that particular topic: Do I Need A Special Thermostat For Radiant Heat?

Do Garage Heaters Use A Lot Of Electricity?

Garage heaters, particularly space heating models, often require significant electricity to function. The average power consumed by a standard space heater in a typical American home is between 5,000 to 30,000 kW per year. However, the US Energy Information Administration (EIA) saw an average of 10,715 kW per month electricity usage for many residences in the country.

Consequently, garage space heaters can skyrocket costs if left unchecked. Homeowners can expect an increase of about $1,200 to $6,000 per year to their energy bills if heater usage is frequent.

Interested buyers can opt for space heaters that require less electricity on average. However, expect that these models to have less heating prowess than their high-powered counterparts. Another option is to use propane heaters, albeit these choices are generally less safe to use than electric heaters.

Still, if these gas-powered warmers are used properly, homeowners can save a significant amount of money from their energy bills.

Where Should A Heater Be Placed In A Garage?

The ideal location for a garage heater is the coldest part of the space. Test different locations in your garage by standing in different areas. Check for drafts or fairly cold activities in those zones. Then, place the heating unit in the coldest area for optimal heating.

Take note that you should avoid placing a garage heater near combustible and flammable objects. These items include (but aren’t limited to) bedding, clothing, curtains, pillows, and paint.
