HEATER CAPACITY:
Direct Contact Water Heater (Patent No. 4574775) is rated at 4,500,000 BTU/HR and is capable
of heating 86 GPM from 45 to 150 Deg. F. Water can be heated up to a maximum of 180 Deg. F.
at a reduced water flow rate.

ESTIMATED ANNUAL VALUE OF HEAT LOAD REDUCTION:
Based upon heating 5,160 GPH of water from 55 to 150 Deg. F., 40 hours per week for 52 weeks
per year, and natural gas at a cost of $7.00 per 1,000 CU FT., the annual cost reduction would be
$24,880.00 when compared to a conventional gas-fired heater or boiler system operating at 70%
system efficiency.

LUDELL EXTENDED WARRANTEE:
Ludell warrants its water heaters against defects in material and workmanship, under normal
use and service for a period of five (5) years after shipment for the fabricated stainless steel shell
