Hot Water

Sunlight has been supporting life cycles on Earth for billions of years.  Why not let the sun heat your water?

A solar hot water system can provide about 70% of your domestic hot water and contribute up to 30% of your heating.  Food-grade propylene glycol (to protect your system from freezing in the winter) is heated in solar collectors on your roof and circulated through a heat-exchanger in the solar storage  tank to heat water for your sinks, showers, laundry, and dishes.  A second heat-exchanger works with your radiant heating system.

You can choose between flat plate collectors or evacuated tube collectors for greater efficiency in low sun conditions, such as cloudy days or in the winter.  Thermal solar systems qualify for a 30% Federal tax credit and a 35% NC State tax credit.
