This trainer represents a state-of-the-art high tech solar hot water heating system as is now being introduced for use in residential and commercial applications.  It features a high efficiency solar collector with a separate boiler (hot water storage tank) that also has a supplementary electric heater.  The supplementary electric heat system is a back up unit to ensure that the water is always a constant temperature no matter what the solar conditions and also compensates for heavy demand usage. 

It comes complete with a centralized electronic controller that operates the unit, electronic temperature meter with six temperature sensors, two water flow meters, expansion tank, electrical circulating pump, water pressure gauge, pressure relief valve, hot water storage tank and the solar collector.  The trainer also has a silk-screened diagram of the solar collection and control circuit, which aids in the explanation of the operation of the system. 

The solar collector plate features the latest technology Thermomax system which has vacuum evacuated heat collector tubes that provide maximum efficiency.  A standard conventional flat plate collector is also available as an option so that efficiency comparisons can be made between two types of collector designs.
