Tank Water Heaters
Traditional tank water heaters store and heat 40 to 80 gallons. They are less expensive to install than tankless units but use energy keeping the tank hot. Typical lifespans range from 8 to 12 years, depending on water quality and maintenance.
Tankless Water Heaters
Tankless units heat water on demand and can save space and energy. They cost more up front and may require gas-line or electrical upgrades. Proper sizing is critical so the unit can handle simultaneous showers and appliances.
Repair vs Replace
A leaking tank usually means replacement. Pilot-light issues, faulty thermostats, sediment buildup, and broken dip tubes are often repairable. A pro can test the unit and compare repair cost against the remaining expected life.
How Water Heater Estimates Work
Estimates depend on fuel type, capacity, venting or electrical requirements, code upgrades, and whether the old unit needs to be hauled away. Tankless quotes should include any necessary gas-line or electrical work.
