Rheem ProTerra 15 A 80 Gal
#14 in 80 GallonFull review
The ProTerra for a home that only has a 15 A, 240 V circuit, such as one left by a small electric tank: it avoids rewiring but gives up some efficiency and first-hour delivery.
The Rheem ProTerra 15 A 80 Gal rates 3.0 among 80 gallon heat pump water heaters; the Rheem ProTerra Plug-in 65 Gal rates 2.6 among 65 gallon ones.
Rheem ProTerra Plug-in 65 Gal
#16 in 65 GallonFull review
A plug-in for replacing a gas tank in a mild-climate garage or basement without new wiring. Buy a size up, since it has no element to fall back on.
