    Rated 4 out of 5 by from Lasts as long as the warranty This came installed in my new home in 2016. It has a 6 year warranty. 3 months after the warranty expired the tank starts leaking all over the basement floor. Currently looking for a replacement.

    Rated 4 out of 5 by from Great system Good unit. They should include the tool to remove the side loop cap inside the water heater. Also, it would be nice to have few flex duct elbows and couplings.

    Rated 4 out of 5 by from Good water heater but noisy Talked with tech support about the noise the exhaust port makes outside the house. I understand that it is a high efficiency water heater with a blower but so was my last state water heater. It is so loud that it is bothering my neighbors. They sell a baffle for it to reduce the noise so you know it can be loud.

    Rated 4 out of 5 by from Direct vent heaters are the best. Too early to tell how it performs, however indications are that it is performing well, even more efficient than my previous State 40 gal direct vent heater. The new heater is cooler on the outside as compared to the old one indicating better insulation. The old one was over 25 years old, (made in 1988). The old one did not fail but changed it as a precaution. I certainly got my moneys worth out of it.

    Rated 3 out of 5 by from New home owner Your website doesn’t show the exact model number on the unit in my home so I had to pick the closest one which GS6-50-YBPDT (LP)…when the tag actually says GS6-50-YBPDT 300

    Rated 3 out of 5 by from Good but noisy The water heater is very good. It can supply enough water to run two showers at a time and did not run out of hot water. My only complaint is that the blower motor is very noisy.
