I just had a 50 gal electric Bradford-White replaced under warranty. It was built in 2004 and I put an insulated blanket over it. I knew this was working because the unit felt warm to the touch under the blanket. The plumber that did the replacement took my blanket and told me "We don't do that anymore. These new tanks are so well insulated."
Is this true or should I get another blanket to cover it?
