Electric water heater works great-energy efficient
Would RecommendI bought this electric water heater 4 months ago and am happy that it has reduced my electric bill being energy efficient. When I discovered that a water heater is the 2nd most expensive appliance in one's home, I replaced it with this new energy efficient one and it has proved itself on my electric bill the past few months - great buy!
