BENEFITS THAT MAKE IT LAST MAXIMUM HEAT EXCHANGER PERFORMANCE ■■ ■■ Durable cast iron primary heat exchanger extends product life - it is not uncommon for cast iron boilers to last in excess of 40 years. Corrosion resistant stainless steel condensing secondary heat exchanger, increases efficiency up to 5% by recouping heat energy from exhaust normally wasted when vented from the building.

BENEFITS THAT PROVIDE COMFORT When matched with a Weil-McLain indirectfired water heater, you will experience virtually limitless hot water for bathing, laundry, dish washing and cooking at a lower operating cost compared to most other alternatives. Our indirect-fired water heaters provide up to twice the peak flow of a tankless coil, 50% more than a comparable sized direct-fired gas water heater, and three times as much as an electric unit.
