Plastic water heater

[Vdawg]

I've seen the Marathon plastic hot water heater and have been intrigued by its purported long life. I also noticed it's made from polybutylene. I know PB piping was known for failures. Does this same risk apply to a hot water tank made of the same material?

Also, are there any health issues with hot water sitting in a plastic tank, such as leaching of chemicals from the plastic into the water over time (particularly because the water is being held in a hot state)?

Thanks for any insights or educated opinions on these questions...

Wikipedia:
Polybutylene is a polyolefin or saturated polymer with the chemical formula ₙ. It should not be confused with polybutene, a low molecular weight oligomer. Polybutylene is produced by polymerisation of 1-butene using supported Ziegler–Natta catalysts. Wikipedia

From the Rheem brochure

• Seamless, blow-molded polybutene inner tank will not rust or corrode

Ah, thanks -- I missed the difference!
