Fast recovery means more hot water and fewer cool water cycles. Six-, 10-, 12- and 16-gallon Suburban gas water heaters feature 12,000 BTUH input and a recovery rate of 10.2 gallons per hour - that's the fastest in the industry. Combination gas/electric models also use a 1,440-watt element to recover an additional 6.0 gallons per hour at campsites. For higher recovery, both the gas and electric element may be used simultaneously.
Suburban also uses a copolymer insulation jacket specially molded to fit the tank. This does a better job of retaining heat than the "cardboard" style used on some competitive models.
