Bradford White Water Heater Rated 5 by Dom Sabatini
  Yes, I recommend this product.
We consulted plumbing supply wholesalers and plumbers. All were unanimous. The Bradford White Brand is #1 all around. We just had one installed, and it is very quiet and well as quick recovery of hot water when it's needed.
