Solar water heating system
Velux America Inc., Greenwood, S.C., introduced a solar water heating system that uses glass-covered solar roof collectors in traditional skylight frames. The Velux U12 collectors use solar energy to heat the water in a home. According to a company release, water heating bills should drop between 50 percent and 80 percent, and the estimated payback period is three years to seven years. The collectors feature a large single pane of clear glass.
