So, you have weather and isolation of their home. Everything has changed, okay most of the CFL bulbs and to install a low flow showerhead. Your programmable thermostat is scheduled for 66 ° at night and use a whole house fan to cool your home in the summer. Now you are considering entering the world of alternative energy, but you do not live in a windy five hectares, or have the funds to invest in a photovoltaic array or solar hot water system. The answer to your dilemma is a heater solar air.
It is first necessary to determine that the window you want to build a solar heater for air. This type of heater runs on a double-hung window, should face south-west to south, and must be in direct sunlight for most of the day. Increase or remove the screen and measure the minimum width of clear opening.
If you are using a piece of old window, you have to scrape the paint ole, glass repair putty, and paint the first band, and clean glass.
Building the wood frame: 1 ½ "wider than the minimum clear opening and 36" to 48 "tall. O building to fit the window of age who are using. Other designs by use of insulation to the frame, but the treated wood is much more durable cover for your hot air will last years and years. Marine grade plywood or 1×6 prime numbers and can be replaced with painted cover.
Add the arms that extend across window to ensure that extend far enough for the air heater can be fixed inside the window. Follow up this issue with parts of coating and other cutting 1×4. Seal all joints with sealant.
Cut rigid insulation to fit into the back, leaving a 5 ½ under a "breach in the top. Use a chalk line to mark a line or a square of drywall with a new sheet in his knife to make clean straight cuts. Secure this in the framework a continuous bead of construction adhesive. Add 2 "spacers along the edges and in the middle.
Add the horizontal rigid insulation between the arms at the bottom, and then one at the center of the arms. Again, sure both pieces with a continuous bead of construction adhesive on all four sides.
Cut the front insulation panel and secure with a continuous bead of exterior construction. Cut the cord from the corner and secure with roofing nails for the isolation of fins to pinpoint. This is a slight modification to the photos shown here.
Paint entire interior of the solar air heater plans black spray paint.
Apply the compressible foam weather stripping along the face of the entire frame. You may choose to use silicone sealant, but this would prevent the elimination of the glass in the future.
Secure the sheet of window glass or old structure. Screw directly through the band structure or use 1 "long pieces of aluminum angle to hold the vessel in place. Insert a piece of weatherstripping between the angle aluminum and glass.
Now you are ready to install your solar air heater and acclimatize to heat so you do not lose more than gain. Open the window and adjust the heater in place. Lower the blade and install foam insulation along the line where the band will comply with the heater. Cut the "air conditioning" foam weatherstipping the width of the blade and inserted between the tapes in the bottom of the outer leaf. Then put a piece of plastic between the air heater arm and jamb of the window, ensuring insurance in place and cover all surrounding surfaces. Filling the gap between the air heater and the window jamb with expandable foam. Finally, install the movie insulating window of the window, ensure the bottom of it to cover the horizontal piece.
Finally, cut a piece of rigid foam to fit in the upper opening of the heater to avoid heat loss during the night, or a roll of old bath towel and placed in the hollow just below the belt. Addendum of a piece of aluminum flashing on top of the solar air heater to help keep water out, and in spring you may want the first and paint the frame treated wood.
