Running cost
Lower power bill than most 29–44 pint models
It uses 35 kWh a year less than the median 29–44 pint model. Over 11 years, the DOE’s average life for a portable, that’s about $70 saved in the United States.

Who it suits
At 32 pints a day, the RHEA-RCS32(Y)-N4-3 fits a wet space under 2,000 sq ft, or a damp one over. It’s one of the cheaper models of its size to run.

The EPA doesn’t list the RHEA-RCS32(Y)-N4-3 as connected. Of the 87 certified 29–44 pint models, 8 are. In a crawl space you rarely open, a connected one saves the trip.

Ask for the pump lift and the lowest working temperature
Pump and cold are the two blanks for the RHEA-RCS32(Y)-N4-3 in our sources. A pump matters when water can’t run down to a floor drain. Cold matters because below 65°F, ENERGY STAR says frost can form on the coils.
Plan the drainFrom the data
Where it stands
- Uses 339 kWh a year, 35 kWh under the median of its class.
- Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
- Of the 87 certified 29–44 pint portables, 7 use less energy.
- At 2.09 liters per kWh, it clears the federal minimum for its class by 31%.The DOE sets 1.60 L/kWh for portables rated over 25 and up to 50 pints a day. Every unit made since June 13, 2019, must meet it.
- Aeocky also makes it smaller, the CS25YA8N7F3(HUMMIGO-25US) at 25 pints, and bigger, the RHEA PRO-RCS50(Y)-N4-3-25 at 44 pints.The bigger one uses 93 kWh a year more.
- Sold since December 2024. Among 29–44 pint models, 2 of 87 came out earlier.
- Not on the EPA’s Most Efficient list, which names 1 of the 29–44 pint models.
- The company that files it also files models under 7 other brands with the EPA, among them Deciuu, Easykey, and Greenlite.
- Another brand near this size: the Deciuu LIBRA-RCS32(Y)-N4-3, at 32 pints and 334 kWh a year.In the United States, this one costs $1 a year more to run.

in the United States
In 24 hours at full output, the RHEA-RCS32(Y)-N4-3 pulls about 4 gallons of water from the air and uses about 7.2 kWh. That day costs $1.33 in the United States.
About 47 such days make up the EPA’s yearly estimate of 339 kWh. If yours runs at full output more often, every extra day adds $1.33.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the RHEA-RCS32(Y)-N4-3 pulls out less than 32 pints a day.
Those 4 gallons need a way out: a hose to a drain, a pump, or a bucket you empty. Our sources don’t say which ones the RHEA-RCS32(Y)-N4-3 has.
