Rated 5 out of 5 by from Great saving really worth the Money spend I brought this tankless Water heater after my friend recommendation. My Gas bill dropped to 30% , that's huge for me. I start looking for Tankless water heater because the standard hot water tank takes lot of space in my Garage. I would recommend this to all who wants to save some Money on heating and save space in their Garage.
