    • It does exactly what it's supposed to do
Style: Natural Gas - Indoor - 5.3 GPM
We had this professionally installed a few months ago, and so far it just works. The single thing I don't like about it is shared with all currently available on demand heaters made today; they require electricity to run. The previous Bosch heater we had ran on a pilot light, and didn't require any electricity to run. What this means is if we lose power (very likely where we live), you have to hook up some sort of alternate power source to get hot water. We have both a gasoline & battery generator, so this isn't as onerous as it might be, but still annoys me. The only heaters that are available that'll run w/o electricity are those designed for camping where you start them manually. I want to take a star off for this, but since it's ubiquitous there doesn't seem to be a reason. ... show more

    • This tankless heater fits easily in smaller spaces and uses less energy.
Style: Natural Gas - Indoor - 5.3 GPM
The water heater takes up much less space than a traditional tank type. The water lines were difficult to get placed right and we had to redo them to elimitate leaks. I still have a drip that requires a bucket under it. The water take several minutes to heat up even on areas very close to the heater. Once hot, it maintains even water temperature unless someone turns some hot water on at another area. We have seen a reduction in our energy use with this heater. ... show more

    • Junk
Style: Natural Gas - Indoor - 5.3 GPM
Wasted money of having it professionally installed and the correct gas line and water line and the vent all for it to throw code 12. Proper gas supply and enough water pressure and still code 12. Props to amazon for taking this junk back.
