The water gets very hot with little wait time for heating to the proper temperature. Yes, we would recommend this type of water heater to everyone that needs a replacement. It did not take the contractor long to install.

    Rated 5 out of 5 by from State Water Heaters...Most Excellent I know a lot of folks will find this hard to believe. I bought this State Direct Vent Natural Gas Water Heater to replace our old State Direct Vent Natural Gas Water Heater that I installed in February of 1993, 25 years ago. The tank finally started leaking. Although these are expensive, they are quality products and worth the extra money. I'm an old odd jobber and natural gas guy and I know the value of buying the best of anything that you can afford. You will definitely save money in the long run.
