Domestic hot water preheating is provided by a solar energy system utilizing 9425 square feet of liquid flat plate collectors. The collectors are double-glazed with tempered glass, have copper absorber plates and a non-selective black coating. A 50% propylene glycol/water solution protects the collectors from freezing down to -20/sup 0/F. A steam-fired heat exchanger and circulation pump with an emergency generator provide heat to protect the collectors below -20/sup 0/F. A 5000 gallon, currently uninsulated, steel storage tank, is located in the existing mechanical room. The preheated water in the tank is provided directly to a steam-fired hot water heater for use in the laundry facility. A heat exchanger provides preheated water to a steam-fired domestic hot water heater. A gas/oil fired boiler provides steam to the hot water heaters. (MHR)
