Maintenance-free, low-cost solar hot water for every climate zone? That is what cleantech start-up Sunnovations claims its breakthrough passive “geyser-pump” system can provide, removing many of the real and perceived barriers to residential solar hot water.
The Tennessee start up was created with a mission to develop solar hot water technology that removed cost and complexity while maintaining performance–a feat the company apparently believes it has achieved with its patent-pending new system, which does away with the electro-mechanical equipment required by your average system, resulting in a more cost effective, easier to install and reliable solar hot water system.
Sunnovations Chief Executive Officer Matt Carlson said, in a statement, “The cost saving and environmental remediation opportunity that solar hot water represents has been sorely underappreciated in the US. Sunnovations has set out to change that by bringing clarity to the cost-saving and environmental benefits to the homeowner as well as standardization and simplicity to the technology behind solar hot water systems.” The Sunnovations solar hot water system is now commercially available through major residential alternative energy installers in the mid-Atlantic region including Pennsylvania, Maryland, the District of Columbia, Virginia and North Carolina.
Hot water production is both the second largest user of power and source of greenhouse gas emissions in American homes, according to the US Department of Energy’s Buildings Energy Data Book. In a given year, between 7 and 8 million replacement water heaters are sold in the US; Sunnovations believes that by switching even a small percentage to solar it will have a substantial positive environmental impact.
