What are water heaters lined with?
The typical tank is steel lined with “glass” (actually porcelain enamel). It contains magnesium or aluminum rods suspended in the tank to fight internal corrosion, which is the number-one reason water heaters fail early.
Can you put a water heater on concrete?
Electric water heaters can sit directly on the concrete floor. There is no risk of accidental ignition of spilled flammable liquids with electric water heaters. They do not have pilot lights as do their gas counterparts.
How long do glass lined water heaters last?
In most areas and for many water conditions they last about five years before they are completely depleted. If you read the manual that comes with your water heater you will see the manufacturer recommend that the anode be inspected at least annually for deterioration.
What are AO Smith water heaters lined with?
In 2004, A. O. Smith reaffirmed its mastery of glass lining technology by introducing patented Blue Diamond™ glass coating on its best Conservationist® residential water heaters. Blue Diamond™ provides the ultimate protection… over twice the corrosion resistance compared to industry-standard glass lining.
Do glass lined water heaters have anode rods?
Modern hot water tanks are made of steel, with a glass lining within. This glass lining serves to protect the steel of the tank from corrosion due to constant contact with water. However, that glass liner will eventually start to split and crack. This is where the anode rod comes in.
Can I transport a hot water heater on its side?
Water heaters can be transported horizontally or laying down on their side. Care must be taken to place it on a flat surface and nothing can be stacked on top of it. Straps must be placed in the right place.
Can I put water heater on bricks?
I always put water heaters up on a couple bricks or patio blocks (2x8x16″ concrete blocks). But most of the houses I work in are older and tend to have water issues – so keeping it a few inches off the ground is always a good idea.
What kind of cement does Hubbell water heater use?
Every Hubbell tank water heater is lined with a minimum of 1/2″ thick Hydrastone cement to ensure protection of the steel tank. The Hydrastone cement lining covers a guaranteed 100% of all interior tank surfaces and is free from flaws or imperfections.
What kind of lining is used in hot water heaters?
The CEMLINE STONESTEEL lining has been manufactured by CEMLINE since 1935. This is a proven method of corrosion prevention for hot water tanks and heaters. This lining application is the result of considerable research by CEMLINE CORPORATION® and a patented product until the patent expired.
Why do you need hydrastone for a water heater?
Due to the longer life and maintenance-free benefits derived from a Hydrastone cement lined tank, Hubbell’s model water heaters significantly reduce total ownership cost of a water heater. Longer tank life is directly attributable to the unmatched tank protection provided by the Hydrastone cement lining.
Do you need an anode in a cement lined tank?
A cement lined steel tank on the other hand does not require an anode because of the thickness and guaranteed 100% coverage of the cement lining over all internal surfaces of the steel tank.
