How to make a solar heater out of beverage cans

Therefore, today we invite you to learn how to make a solar heater with beverage cans, an ideal device to heat small spaces such as a room and reduce the costs of electricity or natural gas consumption in our home. The only thing we must bear in mind is that it will provide heating whenever there is sunlight, so it will be very useful for those who live in arid areas or areas with little frequency of rain.

STEPS

1. Assembling the ducts

The first thing we need to do is collect a total of 196 soda cans. Then we will make a hole in the upper and lower part of each can and we will wash them with water and liquid soap to remove any possible remains of drink that have remained inside.

Join the cans with high-temperature silicone: place the silicone at one end of each can and join it to the end of another, to form a column of fourteen cans (in total we must make fourteen columns of fourteen cans each).

Air for solar heating will pass through these ducts.

Assembling the collector drawer - Materials:

  • Plywood boards
  • White glue for wood
  • High temperature silicone
  • Rock mineral wool (for insulation)

Cut the boards in the desired measurements. Make the joints with white glue and nails (it is suggested that while the glue dries, the panels are held together with some type of clamp).

Once the drawer is attached and dry, we will insulate it with rock wool.

Then we will take a wood the size of the drawer and we will make 14 openings with the circumference of the cans. There the conduits will fit.

3. Assembling the parts

Place a bead of silicone at the end of each can chute and attach it to the hole in the wood prepared for this purpose. Repeat the procedure with all fourteen canals.

Make two openings to the collector drawer, which will be where the tubes that will transport the air in and out of our solar heater will connect. Place an aluminum tube in each hole (one will be for the inlet and the other for the air outlet).

Paint the columns with matt heat black paint so that they absorb more heat.

Cover the box with a polycarbonate surface.

The heater offers a continuous temperature of 70-80 degrees, so it is a good option to help reduce the consumption of electrical energy or natural gas and contribute to the economy of the home.
