SOLAR HEATER GUIDELINES
One
Allow sunlight in but trap heat in (greenhouse effect)
Glass or plexiglass, double paned with air space between works best
Plastic wrap is too thin
Two
Increase the surface area of the water so it will heat quickly
Three
Water should be in or around a conductor (for rapid heat transfer)
Metal is good
Four
The areas containing the water should be black to absorb heat
Five
Insulate outer areas of project to prevent heat transfer
Especially the Ground Over insulation keeps light from entering
and will DROP the temperature
Six
Use of reflectors or mirrors to concentrate light and heat onto water
Difficult to get the right angle due to moving sun
Least important
Seven
Angle object 45 degrees to the SOUTHWEST
MOST IMPORTANT!!!!!!!!!!
