How Solar Hot Water Works [Video]
On average, about 18% of home energy consumption is for water heating, the second largest consumer behind space heating. The primary technology used to do this is the tank-type water heater (both gas- and electric-powered), but solar water heating can be a cost-effective way to generate hot water.
Sunnovations offers a system with less parts, less maintenance, and a one-day installation because it doesn’t have a pump, controller, wiring, or expansion tank.
Sunnovations uses a geyser pump, or bubble pump, that starts working as soon as fluid in the system warms. The gravity-fed system naturally circulates water, so, as explained in the video, a homeowner may get warm water even if the power goes out.
