40 gal. Dunkirk water heater Rated 5 by Joseph D Rinaldi
  Yes, I recommend this product.
I installed this unit In my house about eighteen months ago, and I have not had any problems. It was very east to install and it has been doing a great job at heating the water. I tend to take long showers and I have yet to run out of water, even if I shower after someone else.
