Rotational Molding Machine for Small Parts

Reducing the cost of heating water for household use by the means of a passive solar collector is the goal of this project. A solar hot water heater system with the ability to heat water from a pre- existing household water heater was designed and built to reduce both the cost of heating and reduce the carbon footprint of each household. The panel consists of a frame that is well insulated and uses conduction as well as convection processes to heat the water flowing through the copper tubing. It was determined from testing that four gallons of water could be heated from 65 degrees Fahrenheit to 120 degrees Fahrenheit in one hour. It was also determined that a savings of $10 per month could be achieved by recirculating the water from the household water heater to the solar collector
