I built a new dry cleaning plant for a customer 6 years ago and installed this water heater then and it was only used for about 6 months. It's in fantastic condition. I Bock 100 gallon natural gas water heater commercial grade. Not your typical light weight water heater that rust out in a couple of years. This thing is heavy and built like a boiler, it will serve you well for many years. Over 8k when new, sell price $1, 500 Shipping to you no problem.
