Our experienced solar thermal engineering team offers 3rd party custom designed systems for any application, including solar water heating and space heating systems for apartment buildings, hotels, schools, laundry facilities, car washes, breweries, wineries, and municipal applications. We assess each project, and design energy efficiency measures that can reduce the site’s energy expenses.

We offer complete design services, including material selection, engineering analysis, thermal consideration, and blueprints. At Free Hot Water we use state of the art engineering software along with internally developed tools that allow us to electronically “build” the product to its final design, allowing our customer to review project details before actual construction takes place.

When Free Hot Water designs solar thermal systems, we work with and specify many of the top solar hot water collector manufacturers, solar storage tank manufacturers, pump manufacturers, and specify the best energy efficient materials to match the specific application. We engineer our systems to not only work, but to last.
