Ryan, G P

It is economically practical to heat the schools using water-to-water heat pumps. The Middle School evaluation shows the single stage heat pump to be most cost effective, heaving a return on invested capital of about 19%. Projecting the single stage evaluation to include all the schools, the total conversion cost would be about $800,000. This includes a retrofit allowance of $100,000. The return on investment would be about 19%. Total annual savings in fuel oil consumption would be nearly 150,000 gallons, amounting to a first year savings of about $134,000. Peak water usage would be 1000 gallons per minute, about 45% of that available. Annual water usage would be about 90 million gallons, about 14% of the water used during 1978. This water would be returned to the drinking water system after extraction of heat.
