The water heater is very important because it provides heat to the entire house. The advantages between hybrid water heaters and solar water heaters are that they both have cash incentives that help homeowners save money and they both save resources. There are many benefits to using solar water heaters. Sunlight is free and environmentally friendly and this planet has so much to use (“Know Yourself Better”). The energy of the sun is renewable, the energy of the sun is present everywhere in the world (“Better know yourself”). Solar energy has many uses and can be stored and used. “Solar energy can be used in many ways to provide heat, light, mechanical energy and electricity” (“Better Familiarized”). New measures are being taken in solar technology to save resources. America will save a lot of money and many barrels of oil by going solar, "skyrocketing fuel prices and a nearly 30% tax credit established in the Energy Policy Act of 2005” (“exploiting the sun”). The solar water system won't cost much, only "$3,000 to $6,000" ("Tapping into the Sun"), so it will be affordable. “This technology can reduce the average family's water heating costs by 20 to 40 percent (up to 90 percent in some areas of the Southwest)” (“Tapping into the Sun”). Solar water heaters operate using energy from the sun. There are two types of solar water heater systems, an open system and a closed system (“Tapping into the Sun”). These systems depend on the type of climate in which they are installed (“Tapping into the Sun”). Open systems are worth installing if the weather is sunny all year round, closed systems are better if the weather turns cold. Water can't run in winter so the system will be switched to fuel and in summer when it's hot so the system...... middle of paper ......e Tank; like tankless – these are super efficient alternatives.
