1. Solar Heater Guidelines

2. 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

3. Two
Increase the surface area of the water so it will heat quickly

4. Three
Water should be in or around a conductor (for rapid heat transfer)
Metal is good

5. Four
The areas containing the water should be black to absorb heat

6. Five Insulate outer areas of project to prevent heat transfer
Especially the Ground
Over insulation keeps light from entering and will DROP the temperature

7. 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

8. Seven Angle object 45 degrees to the SOUTHWEST
MOST IMPORTANT!!!!!!!!!!
