Product Description

Open loop systems use pumps to circulate household water through the collectors. This design is efficient and lowers operating costs but is not appropriate if your water is hard or acidic because scale and corrosion quickly disable the system. These open loop systems are popular in nonfreezing climates. They should never be installed in climates that experience freezing temperatures for sustained periods. You can install them in mild but occasionally freezing climates, but you must consider freeze protection Closed Loop Solar Heating Systems are suitable for single and multible solar heating application systems, ***** solar water heating, solar water heating hot tub, solar swimming pool heating or solar space heating ***** Closed Loop Solar Systems are suitable for areas with questionable water quality and all climate ***** Closed Loop Solar Heating Systems are the preferred option for extremely cold areas.
