Solar Thermal Solutions for Industrial Hot Water Preheating

Most commercial and industrial facilities - including food processors, bottling plants and dairies - can benefit from using solar thermal technology to preheat their hot water.

By focusing on preheating your incoming mains water, we can significantly reduce the energy used by your boilers. Harnessing heat from the sun to cut the amount of conventional energy required to heat water delivers longterm financial rewards – monthly energy savings, reduced operating expenses and protection against rising energy prices. It also yields significant sustainability dividends by contributing to a cleaner environment.

Why FAFCO Solar Thermal for Preheating Water?

When it comes to solar, FAFCO’s solar thermal solution for preheating water is the ideal answer.

Unlike the expense of using the sun’s energy to generate electricity, our solution uses a direct approach. We employ solar thermal technology to capture the sun’s heat and transfer it to the water. It is the most cost-effective and efficient use of solar technology for heating water. FAFCO is the oldest solar thermal company in the United States with over 40 years of innovation and leadership in solar water heating. To date, we have nearly two million durable polymer solar collectors in over two hundred thousand installations worldwide. FAFCO’s solar hot water system can easily integrate into both new buildings and existing facilities. Our lightweight, efficient solar collectors can often be installed without roof reinforcement and with minimum operational disruption.

Tap Into Solar Incentives.

Federal, state and local/utility incentives can dramatically reduce the cost of system installation.

DepeDepending on incentives in your area, savings could total more than $500,000, significantly reducing the payback period and increasing the return on your solar investment.


Our FAFCO solar project helps us stabilize />costs while using renewable energy. With the fluctuation of natural gas prices, using solar means that a portion of our energy costs can be anticipated.
