content: I put in a kitchen down stairs because my wife has problems with climbing stairs. I installed this unit under the sink area for use to the Dishwasher and the Sink. Plenty of HOT Water for all the needs. Very easy unit to install. The only problem was the Brass plug that came with the unit,it had bad threads and kept leaking so had to go buy a new plug and no more leaks. Good product for the price.I plan on getting a smaller one(only in propane) for my camp RV.
