2.0 GPM Natural Gas Tankless Water Heater is rated 2.8 out of 5 by 4.
Rated 1 out of 5 by from Not a good unit It's okay as far as using it for the sink or taking a bath but taking a shower is a no go.We just had this installed and when we tried to shower last night it was either scalding you or you were freezing. Messed with the settings and it didn't help. Also you have to have the unit set on winter because the summer setting does not provide enough heat. The unit turns itself on every time you turn on the hot water but if you turn the cold water on full blast it shuts the gas off so you are back to freezing. I do not recommend this product.
