    Rated 5 out of 5 by from Just had my new water installed a little over a week ago. Nice to get hot water in all my bathrooms without waiting or losing the heat after just a few minutes.

    Rated 5 out of 5 by from Fits spac3 and works great I live in a condo and the water heater and HVAC equipment are located in a closet. Obviously a very cramped space closet. This water heater replaced my original 30 year old water heater. The size was exactly the same as my original and the installer Linek Plumbing did an amazing job in such a cramped space.

    Rated 5 out of 5 by from Excellent Low Volume Heater I bought this hot water to replace an older model that was nearing end of expected lifetime use. I am very pleased with this brand and happy to know that I could replace a historically reliable unit with one of same pedigree.

    Rated 5 out of 5 by from Great Tank It has been a month, and so far it is great! This replaced a comparable State model from 1994! If this tank is built as well as my old tank, I will be very happy. I am also expecting this tank to be more efficient as well, but still too early to tell.

    Rated 5 out of 5 by from Solid Water Heater I replaced my identical State unit (that went 18 years) so I got the same again. Very happy. However I'm a female and I like to take a long shower (about 20 minutes) and I run out of the 40 gallons by the end. but the water is piping hot. Excellent! It also stows easily in my basement "crawl space"....4 feet high.

    Rated 5 out of 5 by from Worked perfectly before Hurricane Irma. Now we only have warm water, not hot. Contractors checked it out and will call, but they think power surge since we lost power in the apt., caused the issue.
