*The above charts represent approximate energy savings figures
based on the U.S. Dept. of Energy test method for hot water heaters and a
cost of $1.95 per gallon of propane, $1.42 per therm of natural gas, and $.12
per KW of electricity. Annual fuel useage is constant over the 20-plus year
life span of Bosch AquaStar.
Storage tanks lose efficiency and fuel useage can increase by 30% within the
8-10 year lifespan of a tank.
