HEATER CAPACITY:

Direct Contact Water Heater (Patent No. 4574775) is rated at 3,000,000 BTU/HR and is capable
of heating 70 GPM from 50 to 130 Deg. F. at sea level to 1,000 foot elevation.

ESTIMATED ANNUAL VALUE OF HEAT LOAD REDUCTION:

Based upon heating 4,200 GPH of water from 60 to 130 Deg. F., 12 hours per week for 52 weeks
per year, and natural gas at a cost of $6.00 per 1,000 CU FT., the annual cost reduction would be
$3,840.00 when compared to a conventional gas-fired heater or boiler system operating at 70%
system efficiency.
