About the Honeywell H31MRS series
The Honeywell H31MRS series is a 3.1 cu ft compact refrigerator refrigerator certified by ENERGY STAR. Its official test figure is 270 kWh of electricity a year, which at the U.S. average price of 18.19¢ per kWh comes to $49 a year, or $589 over a typical 12-year life.
That is 25% less energy than the federal maximum for this type of fridge (358 kWh a year), a saving of about $16 a year compared with a model that only just meets the standard.
Among 1,440 compact refrigerator models it ranks #996 for running cost. The cheapest model of this type would save $358 in electricity over 12 years, though it may differ in size and features.
If you want the same type and a similar size for less to run, the Liebherr URP3653 uses 125 kWh a year and would save about $317 over 12 years.
