Solar Thermal System

Working with Building Energy was a pleasure. The work they did looks and works great. After our initial consult on what our needs were, I didn't have to worry about a single thing, they took care of it all. I highly recommend them and will use them for our next project.” Rebecca Grannis

A solar thermal system, also known as a solar hot water system, uses the sun's energy to preheat water for domestic use (showers, laundry, etc.) Heating water with the sun is one of the most cost effective applications of solar energy. It can greatly reduce your use of fossil fuel or electricity for heating domestic hot water.


A solar hot water system provides immediate, often substantial, return on investment by reducing fuel costs associated with traditional water heating systems. And it's one of the most environmentally responsible options since it produces zero carbon dioxide emissions. By using the sun's rays-the ultimate renewable energy source-you also contribute to the nation's energy security by reducing dependence on foreign energy.

  • Can be used on existing as well as new construction.
