Water Heater Ratings: Top Water Heater Sources of Ratings | Plumbing Tips | Scoop.it

"A related October 2008 article, "Cheaper Hot Water" by Dave Yates, suggests six ways to lower water-heating costs. He recommends adding a thermal-expansion tank to any storage water heater that lacks one, to extend the life of the entire plumbing system as well as the water heater itself. Yates also discusses replacing an older storage water heater with a sealed-combustion gas model with better insulation and 90 percent efficiency. But he notes that more efficient water heaters can have lower recovery rates, so you may need a bigger tank."
