System Design Description
The solar closed-loop heating system consists of the Oventrop Regusol 130 EL pump and control station,
one OV-5 evacuated tube collector, and an 119 gallon glass lined tank with two internal coils. An expansion tank is
installed at the Regusol on the safety group. Oventrop NT propelyne glycol antifreeze is filled into the closed loop
system through the Regusol fill and flush valve.
Cold water is piped to the solar tank. An anti-scald valve must be installed for hot water mixing to hot water
fixtures if the solar tank high limit in the Regusol controller is set above 120
o
F. The top coil is piped to the boiler in
the manner of a standard indirect water heater.
