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.

about eight to 12 yearsBased on the manufacturer's suggested service life, the life expectancy of a water heater is about eight to 12 years. That varies with the location and design of the unit, quality of installation, maintenance schedule and water quality.
Stainless Steel Water Heaters Are Lighter
Stainless steel water heaters are lighter than glass-lined ones because the material itself is thinner, and they don’t have any additional lining.
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.
Final Verdict
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.

This style of water heater is unique in that is uses heat in the air and in the ground to heat water. This means that electricity is only used to move heat from the ground or air to the water, instead of the alternative where electricity is used to generate heat.
What is tankless water heater?
A tankless water heater, as you can probably guess, has no tank. Instead, there are super-heated coils that fill with water and heat water in a flash as you need it , which is why it is alternatively known as an on-demand water heater. This is great for heating water quickly, even for large families who need a large amount of hot water at once. This style of water heater comes in different sizes, and you do need to ensure that you have the right size for your household, as a smaller tankless water heater will not be able to keep up with your water usage otherwise and it will result in lukewarm or cold water. These models work well in homes that use natural gas to power their water heater, but larger models require a larger gas line and more gas to run correctly. Larger tankless hot water heaters that run on electricity may require you to increase the electricity capacity of your home, which could be costly.
