Our customers love their solar hot water systems. Solar thermal technology has been perfected over many decades to provide a greater abundance of hot water than possible with electric or gas heaters - all with the sun's free energy. Because the initial investment is small and the monthly savings are large (reducing the average gas bill by 25%), solar water heaters provide a quick return on investment. A popular option for homes, offices and factories, solar water heaters offer low-cost, low-maintenance hot water year-round.
