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 80 gallon stainless steel tank with 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 and in series with the back-up hot water heater. Solar bypass valves
are installed for servicing the solar tank. Back-up hot water heater bypass valves may be installed to bypass the hot
water heater. 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
