AO Smith Cyclone Xi 50-Gallon Commercial Gas Water Heater (FCG-50) Review
The AO Smith Cyclone Xi 50-Gallon Commercial Gas (FCG-50) is a smaller-capacity Cyclone for commercial-residential crossover applications. The "FCG-50" identifies the 50-gallon variant in the Cyclone commercial line.
Specs: 50 gallons stored, 100,000 BTU input (lower than 199K BTU larger Cyclone variants), UEF 0.97 condensing, 200-gallon FHR, 8-year tank warranty. Power-vent PVC venting. Cyclone heat exchanger uses spiral flow paths.
The Cyclone Xi 50-gallon serves light commercial applications (very small restaurants, single-bay salons) or large residential households where standard 50-gallon would be tight. UEF 0.97 is among the highest in the gas tank category.
About $2,800 unit, $4,200-$5,500 installed depending on venting work. Right buyer: commercial-residential crossover with 50-gallon capacity sufficient.
