Our read & the right size
At 5.03 kWh/day, the True Refrigeration GDM-26F-HC~TSL01 runs in the less-efficient 82% of the 103 comparable 1-door reach-in freezers we track — about $59/yr over the median.
A single-door reach-in freezer (~20 cu ft) covers a small operation or a backup to a walk-in. Frozen product is dense, so a smaller box goes further than it does in refrigeration.
21.83 cu ft is roughly 1.1× a typical home refrigerator — about 11 full sheet pans or ~18 cases of product (varies with shelving).
