Gas and oil water heatersWhen it comes to water-heater selection, two considerations are key: a unit’s fuel type and first-hour rate (FHR). Consider both, but focus most on a unit’s FHR – the number of gallons of hot water that can be produced in the first hour – to avoid the disappointment of running out of hot water.24 Heating & Cooling provides 24-hour assistance with water heater services and repairs in Chicago and suburbs.Recommended productsGas water heaterProducer/brand: American StandardModel/submodel: 75-76-ASEnergy saver: n/aProduct highlights: Show highlightsHeavy Gauge Steel Tank for extra years of trouble-free service.Inner tank glass-lined with Dura-Glas™ and fired at 1600° F for optimum protection from the effects of corrosion.R-16.7 non-CFC foam insulated to save energy and reduce fuel costs by maximizing heat retention.Two anode rods to prolong tank life.Self-Cleaning turbulence inducing cold water inlet-tube engineered to diminish hard water area sediment deposits.Full size hand-hole cleanout for eased tank inspection and/or removal of sediment deposits.Furnished with four heavy gauge steel legs designed to maximize durability and afford rock-steady installation.Automatic non-electric gas thermostat adjustable to 180° F.
