Frequently Asked Questions

Does an indirect water heater need an anode rod?

An indirect water heater made of glass-lined steel needs an anode rod to fight against corrosion inside the tank. If your water heater is made of thermoplastic or stainless steel, an anode rod is not required.

How often should a water heater anode rod be replaced?

A water heater anode rod should be replaced every three to five years so it doesn't corrode inside the tank.
