As per the\nEESI, residential solar water heaters cost around $2500, compared to $150 to\n$450 for electric and gas heaters. With savings in electricity or natural gas, the\ninvestment in solar water heaters gets covered within four to eight years. <strong>Solar\nwater heater systems<\/strong> have a working life of approximately 40 years, the\nsame as conventional systems. So, after that investment gets covered, zero\nenergy cost essentially means having free hot water for years to come.<\/p>\n\n\n\n<p>You may\nget amazed to learn that in the <strong>United States<\/strong>, the federal government\noffers homeowners tax credits of up to 30 % of the cost of setting up a <strong>solar\nwater heater<\/strong>. The credit is not available for hot tub or swimming pool heaters,\nand the <strong>solar water heating system<\/strong> must be certified by the Certification\nCorporation and Solar Rating.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Things to know before installing a solar water heater<\/h2>\n\n\n\n<p>According\nto the United States Department of Energy\u2019s, zoning and building codes relating\nto the installation of <strong>solar water heater systems<\/strong> usually reside at the\nlocal level. So, customers should make sure to research the standards and hire\na certified solar heater installer familiar with local requirements. <\/p>\n\n\n\n<p>Homeowners\nbeware: Most municipalities require a building permit for the installation of a\n<strong>solar water heater system<\/strong> onto an existing house.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The mechanical engineers at Wisconsin\u2019s Solar Energy Laboratory University have shown through their studies that an average four-person household with an electric water heater needs about 6,400 KW hours of electricity every year to heat their water.
