Eco-Logical OMNI-50HP1-1A 50-Gallon is a heat pump (hybrid electric) water heater from Eco-Logical with a 46 gallon rated tank and a 50 gallon first-hour rating at a 3.3 UEF — 681 kWh/yr certified use, 72.7 in tall.
Our take
The lowest certified running cost in the 50-gallon heat-pump class — about $116 a year, 681 kWh — belongs to this 120-volt split system, though under a Low draw pattern: it is tested delivering less hot water, and its 50-gallon first-hour rating (2–3 people) reflects that. The split compressor operates to 5 °F, far beyond integrated units, and the tower is a striking 72.7 inches tall, the class maximum, while only 16.1 inches across. R-513A refrigerant, connected-capable, 14.5 A at 120 V. Single badge. Right-sized households will do very well; wrong-sized ones will run out.
Best for: Small cold-climate households minimizing both circuit load and running cost.
Trade-off: Six feet of height, modest capacity, and a split install.
