What do we mean by a Solar Garage Heater, and how does it work?

A solar air heater comes with the latest technology and is an active system, which you can use to heat spaces like a garage. It works on the principle of warm air rising and cool air circulating through a solar collector. It picks the heat, warms the room efficiently and quickly, and works using renewable energy. 

Why use a Solar Garage Heater?

The solar heater uses the sustainable form of energy, and the solar collector uses sunlight to heat the air, which gets transferred to the garage or any working space. The solar garage heater uses renewable energy and provides free and clean air from the sunlight that hits your garage walls.

Are they worth it over other conventional options? 

The current cost of fuels in the market has turned many industries and people towards cheaper options such as solar garage heater, which uses solar irradiance which is cheaply and abundantly available. 

Should you just DIY a solar garage heater?

Heating your house or garage doesn’t have to be expensive. You can always select a sustainable form of energy to help you save on energy costs. Solar air heaters are usually cost efficient and not the replacement of traditional heaters but a supplement. You can create your DIY solar-powered heater with a few simple materials and some easy steps without electrical expertise.

The concept of air passing through the panel and heat flowing into the room is usually the same convection method. In this solar heater, a fluid, in our case, rises when it gets hotter. At the same time, the denser, colder air goes down through gravity. It results from heat transfer. 

Tip: To have more heat transfer, use a fan. Also, by painting the boxes black, you heater will absorb more heat, making your room warmer.

Required Materials

Measurements depend upon the size of your window and you large heater you want to build.

  • Board Insulation
  • Great stuff foam insulation
  • Metal Duct Tape
  • plyboard
  • Black spray enamel
  • 3 v computer fan. 
  • 3 v solar cell (s).
  • screws
  • brad nails

Steps to create a solar-powered heater are:-

  1. The can’s collected should be free from dents, cracks, or tears—Sand the surface of the cans with sandpaper, to roughen the surfaces so that you can paint them easily. It would be best if you assembled the side of the can by the side of the metal heating tubes. Use punch holes to create baffles between the cans. Permanently remove or cut the tops off to make stacking better.
  2. Paint the sanded cans, and plan your array. You can place cans side by side, leaving small spaces to ensure the board will not break when drilling.
  3. Make sure the pattern you create, line up and run straight within the window box you created. Once you complete the top, use it as a blueprint to make the bottom layer.
  4. Make sure the tubes are of the same height. A small chamber should exist on the top and bottom of the framework to collect and exhaust the air. 
  5. Now the can tubes are assembled. Carefully tape the pipes through the bottom framework to the top and handle it cautiously as rough handling may break the seals. In this step, the vents are installed, and we drill holes for effective heating. Install vents into the pre-drilled holes.
  6. Ensure the fitting of the computer fan and use black electric tape after splicing. Keep some space in between the board for the fan to spin freely.
  7. Your solar heater is ready to make sure the sun hits the solar cells so that the fan can engage.
