  1. Solar Hot Water Heating Name: Ho Yan To

  2. Objective • Different Types of Solar Systems • Types of Solar Panel • Solar Hot Water Heater System and your home • Cost of installing and lifetime • How it would effect your life • Money saving • Huge change in your lifestyle?

  3. Types of Panel • Flat-plate collectors Insulated metal box with glass and glazing cover and a dark-coloured absorber plate. Heats at less than 82°C(180°F)

  4. Types of Panel • Evacuated-tube collectors Glass tubes with selectively coated absorbers inside transferring energy to heat. Most efficient at above 82°C(180°F). • Concentrating collectors Concave mirror with focal point directed to an absorber or receiver. Can reach higher temperature than Flat-plate and evacuated-tube collectors.

  5. Your home and the system • Installation varies depending on size of family, tanker, and solar system; type of roof, building codes, and collectors. Usually range from $1,500 to $3,000. • Some states offers rebates to reduce costs. • Example, family of four saves up to 85% yearly. • Can heat swimming pools and hot tubs. • Long lasting parts and easy maintenance.

  6. Lifestyle • Cannot totally replace conventional boilers but enough to save significantly. • Best results for hot water around late morning and early afternoon. • Hot water use should be spread out over a week so solar system can be most efficient. • Lower mortgage rate. • Better environment. • Still effective in colder climates
