Rheem ProTerra 15 A 50 Gal
#16 in 40–50 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.
3.0/5
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.
