What does glass lined water heater mean?
Glass-lined water heaters have anode rods. The tanks are made of steel lined with glass. The glass does protect the tank against corrosion, but it is vulnerable to cracking and leaking, so anode rods are still required. The glass also helps to insulate the tank, making it more energy-efficient.

Glass-Lined Water Heaters Need Anode Rods
Anode rods are not essential to the daily functioning of water heaters. However, they are vital to the continued functioning of certain water heaters.
Durability of Stainless Steel and Glass-Lined Heaters
Glass-lined water heaters are not as durable as stainless steel ones. Their durability rests on the anode rod to a large extent.
Maintenance of Water Heaters
The care required for stainless steel heaters differs widely from the care necessary for glass-lined heater tanks. But they have a few steps in common, so let’s cover those first.
Market Availability
Stainless steel water heaters are not as common as glass-lined heaters. Therefore, they can be difficult to come around, and the variety of the available units is more limited.
Stainless Steel or Glass-Lined: Comparing the Cost
Price can often be the determining factor when we are looking to purchase a new water heater. Since they are already a pretty significant expense, most people will try to factor this in and look for cheaper models.

Every person has different needs and preferences regarding their water heater. While stainless steel heaters can be the winner on paper, some people might benefit more from glass-lined heaters.
Purpose of Glass Is to Protect Tank From Corrosion
Glass lining is one of the safety features of water heaters. It serves as a barrier to stop the water from being in constant direct contact with the steel water tank. Therefore, the lining provides the tank protection from corrosion to some extent.
Glass Lining Is Not Perfect Barrier
Glass lining doesn’t last very long when left on its own as the sole source of rust prevention. This is due to its somewhat fragile nature.
Is Glass Lining Pointless?
Just because an anode rod is required, it does not mean that the lining doesn’t have its place in the water heaters. It still plays a vital role in the heater’s safety and efficiency.
Indirect Glass-Lined Water Heaters
Indirect water heaters with glass-lined tanks also require anode rods because the tank is still present in the unit. However, the tank takes less strain in general in these models as there is no compounding factor of the harshness of the heating element or gas flame.
