Gas and oil water heatersPrint

When 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.
