Key Specifications/Special FeaturesTwo basic types:
Active systems utilize circulating pump and some type oftemperature control
Passive systems do not have any moving parts and rely on basicprinciple of physics hot water raised and cold water falls
Active systems all function basically same variousconfigurations (closed and open loops), depending on customersclimate zone
Passive systems come in two basic types:
Thermosyphon and batch
Each system has distinct advantages
Active systems use electric pumps, valves, and controllers tocirculate water or other heat-transfer fluids throughcollectors
Usually more expensive than passive systems are generallyeasier to retrofit than passive systems
Storage tanks do not need to be installed above or close tocollectors
Relies on natural circulation of water between collector andtank or heat exchanger
As water in vacuum tubes are heated rise naturally intotank
Cooler water in tank flows down to bottom of vacuum tubes,causing circulation throughout system
Following picture simplest of installation configurations
Tanks are low pressure and open vented
Tanks are manually filled by opening tap in house
Once tanks are full water runs out through overflow pipe fedback down into house
Water starts flowing out tanks are full
Using water tank gradually drains until empty
