Typical Solar Water Heating Systems Available


Swimming Pools
The swimming pool solar heating system would normally connect into the standard pool circulating system and operate in conjunction with a conventional heater. The system that the city installs would include the collectors, the plumbing between collectors and the pump/filter equipment, and a thermostatic control to regulate the flow to the collectors. For more information, see Solar Pool Heating Systems (PDF). 

Domestic Hot Water (Multi-Family)
A solar domestic water heating system would include two to three collectors, a storage tank, circulating pump and an automatic control. Since solar cannot provide 100% of the heating, some conventional backup heater would be required. This could be installed as a separate hot water heater plumbed in series with the solar storage tank, or the solar system may be installed with an electric heating element integral with the solar storage tank. 

Process Water Heating
Solar process water heating could be useful for any of a number of industrial or commercial processes. Typically, the water could be preheated to approximately 100° to 160° F. Some conventional heating system would usually be required as a backup.
