Garage Heating. Unit Heater.

When it comes to garage heating the first thing to ask is are walls and ceiling insulated? Insulated garage door is a must. You can get a garage door insulation kit if needed. And of course plug all air gaps. And if an attached garage, good insulation may be all you need to keep the space above freezing for paint cans, gardening, tools and workshop.

With frigid temperatures working in a garage can be tough. A small space heater will only raise the inside temperature a few degrees. Portable heaters generally are not powerful enough for a good sized garage. The best garage heating are those that are efficient and powerful.

Ceiling mounted garage heater located in a corner can be a good start. The downsize is if you work closer to the floor heat will be harder to come by. Electric baseboard or hydronic baseboard heater can help.

Garage heating choices.

Unit heaters can include: radiant heating, infrared heating, electric heater or gas furnace. Many heaters can have a remote control thermostat to make life easier.

  2. An infrared garage or shop unit heater focuses the heat on people or work areas. Indirectly the infrared heating warms the surrounding air and highly efficient, but more expensive. Provides consistent, steady warmth without a fan.
  3. Electric garage heater for powerful output in garage, work space, basement. Mount on the ceiling or where you like. Can have thermostat to set temperature. Some models come with adjustable louvers to direct heat where you want it. Can be expensive for quieter fan and more options or budget-friendly with a louder fan, less power and fewer options.
  4. Gas garage furnace. Unit heaters built-in electric fan pulls cool air into the heater rear then over a heat exchanger, forcing hot air into the garage. Common garage furnace heater can be 30,000 to 75,000 Btuh with 80+% efficiency to hold off the chilliest of winters. Proper venting is required in the roof or out a wall
  5. Ductless mini split electric system can be a nice option but more costly.
