Buderus solar is one of the largest and most reputable manufacturers in the world. They have been manufacturing and designing solar water systems for over 25 years, and continue to invest in research and development to bring innovative, high quality, solar products to the market.

A Buderus solar thermal system for hot water consists of a solar collector, a pump station, and an indirect hot water storage tank. The solar collector, which is located on the roof, collects the sun’s energy and transfers the heat to the storage tank via the tanks internal heat exchanger. The storage tank in turn allows the hot water to be stored until it is used. The controller activates the system’s pump when there is enough solar energy to create hot water. Even on a cloudy day, light penetrates the cloud layer and heats up the solar collectors.

An existing Buderus wall hung or floor standing boiler can be combined into the solar system as a back-up for domestic hot water. The solar system can also complement the boiler for space heating by reducing the number of boiler starts, saving on costly fuel.

A typical Buderus residential solar hot water system using 2-4 collectors takes about 1-2 days to install depending on location and roof type. Larger commercial systems take longer because of the scale, equipment, and labor required. The typical life expectancy of a Buderus solar hot water system is 20-30 years. If the system is properly maintained, it can last over 30 years. Every 5 year, the heat transfer fluid should be checked and replaced. The pipe insulation and controller settings should also be checked as part of the annual system check-up.

A residential solar water heater will offset greenhouse gas emissions by about 1,600 pounds of carbon dioxide (CO2) per year. That’s equal to the amount of CO2 released by an average vehicle every 1,700 miles!
