Navien NWP500 65 Gal
#5 in 65 GallonFull review
Navien’s stainless-tank hybrid, sold through plumbers, with a 10-year warranty that includes a year of labor. Its heat pump stops below 41 °F room air, so it suits a basement more than a cold garage.
The Navien NWP500 65 Gal is the better heat pump water heater overall, rated 3.7 to 3.4. The Navien NWP500 65 Gal leads on efficiency and hot water. The GE Profile 65 Gal 120V wins on cold rooms.
GE Profile 65 Gal 120V
#13 in 65 GallonFull review
The most efficient 120 V plug-in here, and the quietest, for replacing a gas tank without new wiring. It can be rewired for 240 V later if the household outgrows it.
