It is important to replace your existing water heater with one that is compatible with your home. There are several criteria you should consider before selecting a water heater. Use this guide to decide which storage-tank water heater would be best for your home.
Gas water heaters: Gas water heaters use a burner at the bottom of the tank to heat water and require ventilation for exhaust gases.
Electric water heaters: Electric water heaters use electrical heating elements instead of a gas burner and do not require ventilation.
