GREE GRS-3.0Pd/TD50GANhA-D 50-Gallon is a heat pump (hybrid electric) water heater from GREE with a 55 gallon rated tank and a 80 gallon first-hour rating at a 4.02 UEF — 1234 kWh/yr certified use, 66.9 in tall.
Our take
GREE's entry actually holds 55 gallons and certifies High-draw with an 80-gallon first-hour rating — the second-highest in the 50-gallon class — at a 4.02 UEF (85th percentile). The 1,234 kWh / ~$210 annual figure reflects the heavier High-draw test rather than waste. It is physically imposing: 66.9 inches tall and 25.2 inches across, both near the class maximums. The R-32 refrigerant (GWP ~675) is a mid-path between R-134a and CO₂. Not connected-capable, single badge, 240 V at 23.9 A with a 35.6 °F cutoff.
Best for: Big-family delivery with well-above-median efficiency.
Trade-off: Bulk in both dimensions, and no smart-grid features.

Who is the GREE GRS-3.0Pd/TD50GANhA-D 50-Gallon for?
Its 80 gallon first-hour rating suits a
household of 5+ people under DOE sizing guidance.
Estimated running cost: about $210/year at the national
average electricity rate (1234 kWh/yr certified use).
Needs a 240 V circuit; at 23.9 A max draw plan for a 30 A breaker (NEC 125% continuous-load rule).
The heat pump compressor operates down to 35.6 °F ambient — below that, backup
elements take over.
Is the GREE GRS-3.0Pd/TD50GANhA-D 50-Gallon ENERGY STAR certified?
Yes, the GREE GRS-3.0Pd/TD50GANhA-D 50-Gallon holds a current ENERGY STAR certification for water heating efficiency (UEF 4.02).
How much does the GREE GRS-3.0Pd/TD50GANhA-D 50-Gallon cost to run per year?
About $210 per year at national average energy rates, based on its certified annual energy use under the DOE test draw pattern. Your rate and usage change this figure.
What electrical circuit does the GREE GRS-3.0Pd/TD50GANhA-D 50-Gallon need?
The GREE GRS-3.0Pd/TD50GANhA-D 50-Gallon runs on a 240 V circuit drawing up to 23.9 A; per the NEC 125% continuous-load rule plan for at least a 30 A breaker (check the installation manual for the required circuit).
Is the GREE GRS-3.0Pd/TD50GANhA-D 50-Gallon a smart water heater?
No, the GREE GRS-3.0Pd/TD50GANhA-D 50-Gallon is not connected-capable — it has no app connectivity or demand-response support.
