A standard tank water heater in Utah lasts 8-12 years. Tankless units last 18-22 years. Utah's very hard water shortens tank life by 2-4 years unless the tank is flushed annually and the anode rod is replaced every 3-5 years.
A standard 40-50 gallon tank water heater in Utah typically lasts 8-12 years — shorter than the national 10-15 year average because Utah's hard water (15-25+ grains per gallon) deposits scale on the bottom of the tank, insulating the burner and stressing the steel.
Tankless units handle hard water much better and commonly last 18-22 years. You can extend tank life significantly by draining and flushing the tank annually (removes sediment) and replacing the sacrificial anode rod every 3-5 years (prevents tank wall corrosion).
Signs your water heater is close to the end: rusty hot water, popping or rumbling noises from sediment on the burner, water pooling under the unit, or age over 10 years with any leak at all. Once a tank leaks, there's no repair — the steel has failed.
