11 Easy Ways to Keep Your Garage Warm This Winter

A cold garage can ruin your productivity. Whether fixing a car or crafting wood, you need a warm space. Many garages lack insulation, which leads to freezing air and icy tools. Without action, even strong heaters may not help much. Use these smart solutions to heat your garage in winter efficiently and comfortably.

1. Use a Properly Sized Space Heater

Visit a hardware store and grab a heater that fits your garage’s square footage. For larger areas, ceiling-mounted forced-air heaters work best. These models distribute heat evenly and often come with thermostats. Add a baseboard heater near your workbench to warm your feet. Together, they provide consistent comfort.

2. Add Fiberglass Insulation to the Walls

Uninsulated walls lose heat fast. Fill each stud bay with fiberglass batt insulation. Cover it with drywall, plywood, or OSB. This combo traps warmth and reduces your heating bills. Plus, it’s a manageable DIY job for most homeowners.

3. Insulate the Garage Door

Garage doors are often thin metal that lets in freezing air. Attach a garage door insulation kit to trap warmth. Most kits are easy to install with basic tools. This small upgrade can increase the garage temperature by 10 to 12 degrees.

4. Seal Drafts and Gaps

Cold air sneaks in through unsealed cracks. Apply weatherstripping around the garage door frame. Replace worn door seals at the bottom. For drafty windows, apply shrink-film insulation to keep out chills.

5. Install Radiant Floor Heating

Radiant heat starts from the ground up. This option works best if you’re pouring a new floor. Pipes installed beneath the concrete circulate warm water, heating the entire space. It’s dust-free and great for woodworking.

6. Try a Portable Propane Heater

Propane heaters offer strong heat without tripping breakers. A 20-pound tank powers smaller models. For larger needs, install a bigger tank and gas line. Use vent-free models for safety in enclosed spaces.

7. Consider a Wood-Burning Stove

A wood stove offers warmth and a cozy vibe. Choose a model with a safe, insulated exterior. Vent it properly through the roof to meet local codes. Always place it away from flammable items.

8. Use a Kerosene Space Heater

These torpedo-style heaters shoot intense heat across the room. They’re great for targeted warmth. Ensure your model is safe for indoor use to avoid harmful fumes.

9. Install a Radiant Heater

Radiant heaters warm objects and people directly. Ceiling or wall-mounted models work best. Some include lights to brighten your workbench. They’re efficient and don’t stir up dust.

10. Expand Your Mini-Split System

If your home has a mini-split, you may add a garage unit. Check that your compressor can handle the extra load. This is a cleaner, quieter way to maintain consistent warmth.

11. Cover the Floor

Cold concrete floors chill your feet fast. Lay down rugs or interlocking rubber mats. These insulate your feet and make long projects more comfortable.

Stay Warm and Productive This Winter

Combining several methods will help you heat your garage in winter without breaking the bank. From insulation to heaters, small changes go a long way.
