Solar water heating isn’t new, but technology has transformed it. Today’s systems heat water with the sun and use little purchased energy. Crescent Custom Homes installs solar water heaters in new and existing homes to benefit our planet and make hot water affordable for those of us paying high energy prices. ![New-Maui-home-with-solar-water-heating-system-and-stone-retaining-wall-1](https://www.crescenthomesmaui.com/hs-fs/hubfs/New-Maui-home-with-solar-water-heating-system-and-stone-retaining-wall-1.jpg?width=600&height=245&name=New-Maui-home-with-solar-water-heating-system-and-stone-retaining-wall-1.jpg) A solar water heater system on a new home built by Crescent Custom Homes ## What is a Solar Water Heater? A solar water heater stores water that has been constantly heated by the sun and is ready to disperse it anytime to ensure you have a hot shower. The purpose of a ceramic solar water heater is to provide hot water when you need it at a low operating cost. In times when solar heating hasn’t been enough, the backup element will utilize traditional energy to ensure your home has hot water. Fully automatic controls ensure temperature control is met. When our glorious Hawaiian sun creates truly hot water, the tank ensures it stays hot for up to two days due to its efficiency and engineering. More importantly, almost no energy has been consumed, resulting in true sustainability and environmental consciousness while saving our homeowners money. Many of us remember the old water heaters. One day we’d look in the garage or a utility closet, and water was everywhere because the bottom of the unit finally rusted and fell out. This is no longer a problem for heaters using advanced materials. With Vtriglas lining’s engineered enamel formula, the highly corrosive effects of hot water are no longer a problem. ![Solar-water-heating-system-1](https://www.crescenthomesmaui.com/hs-fs/hubfs/Solar-water-heating-system-1.jpg?width=600&height=223&name=Solar-water-heating-system-1.jpg) Close-up of a roof-top solar water heating system ## How Solar Hot Water Heating Works The most significant power source we have access to is our sun. A 100-mile by 100-mile solar farm in the Nevada desert could power the entire U.S. The sun puts more energy on the earth in an hour than the whole U.S. uses in a year. Solar water heating has water passing through roof-mounted systems that efficiently absorb the sun’s power. Solar energy is amplified to heat the water which is then stored in the ceramic tank that keeps it hot for up to two days. ![Solar-water-heating-system-on-roof-of-new-home-1](https://www.crescenthomesmaui.com/hs-fs/hubfs/Solar-water-heating-system-on-roof-of-new-home-1.jpg?width=600&height=335&name=Solar-water-heating-system-on-roof-of-new-home-1.jpg) New home under construction with solar water heater installation ### Start Saving Now Electricity on Maui is costly.
