how thick is the tank liner and what is the "R" value?

how thick is the tank liner and what is the "R" value?
Asked by: Dp
Unfortunately we do not have that information about thickness of the insulation. Also it is not required by the government to rate water heaters by "R" value. The government requirement is now and EF (Energy Factor). In the instance of this unit the EF rating is .59.

Performance 40 Gal. Short 6 Year 36,000 BTU Natural Gas Water Heater is rated 4.5 out of 5 by 561.
Rated 5 out of 5 by from Perfect fit to replace old water heater I installed this water heater myself. I am not a plumber so it was important to find a water heater that was as close to the size of my old water heater. I have copper tubing plumbing so it was easy make the adjustments.

Rated 4 out of 5 by from Very happy with product I replaced my last AO Smith water heater(s), with the Rheem product and so far we are very satisfied. The previous AO Smith product was replaced twice due to leaking tanks after only 2 years which was very surprising and dissapointing and extremely frustrating. I am very hopeful that this Rheem product will provide many years of trouble free service. I really like the design of the air intake and havining on the sides versus the bottom and no filter to clean. I would have given 5 stars but still waiting to see how the tank holds up.

Rated 5 out of 5 by from Love This Water Heater Replaced a 20 year old 40 gal water heater and could not be more delighted. Not only was the calcium buildup in the old WH causing low efficiency, but it actually reduced the volume considerably and we were constantly running out of water. The new 50 gal unit heats the water fast and has never run out.

Rated 5 out of 5 by from Great performance installed about 15 months ago unit is great never out of hot water, previously had whirlpool water heater and it was a piece of junk, had to replace control valve 3 times in 3 years, then they would not honor warranty when it leaked, have had no issues with the Rheem
