Customers Say

AI-generated from the text of customer reviews

This gas water heater strikes an impressive balance between performance and practicality for modern homes. Its slim profile fits neatly into tight spaces while delivering enough hot water for 3-6 person households with minimal wait times between showers. The unit operates remarkably quietly and features an intuitive LED display that takes the guesswork out of monitoring system status. Built with durability in mind, the corrosion-resistant tank and premium materials provide lasting reliability, while comprehensive safety features offer peace of mind. Energy-efficient operation, including a useful vacation mode, helps manage utility costs. Though professional installation is recommended, the straightforward design makes maintenance accessible for homeowners.

Rated 5 out of 5 by from Cool extra features and quality parts visible My last water heater lasted 19 years. This has same heavy duty parts as my old one as far ax i can tell. The big box stores use plastic drain connectors this is brass. The warrenty on tank heater is 12 years longer big box stores as well. It has error codes on it my last one didnt but this may be technology advance. So far so good but just got it so time will tell

Rated 5 out of 5 by from Gas water heater 40gal gas water heater. Installed 11-21-2024 Had it installed by local plumber. choose because of the 12 yr warranty. Choose over a more expensive mfg because of the longer warrenty.

Rated 5 out of 5 by from Improvements make a great water heater better We are anxious to place this water heater in service as it replaces the same model that had a non repairable leaking drain valve . We invested a lot of effort choosing this model. While having to get a replacement was unsettling, GE’s quick response to detail information we provided restored our confidence in our choice of brand and model we chose. Our contractor made the change out as near seamless as possible.

Rated 5 out of 5 by from Slightly lower than RHEEM I bought one GE 50 gallon hot water tank 12 year warranty and 50 gallon tank 6 year warranty in 2013. Both are still working well. The reason I bought this one, because GE hot water tanks are the best. and also, I want to have one ready for replacement.
