Vissani VAD35S1AWTS dehumidifier: specs and cost to run

Our read

Who it suits

At 36 pints a day, the VAD35S1AWTS fits a wet space under 2,000 sq ft, or a damp one over. Its running cost is close to the median, so drainage, noise, and price matter more.

Running cost

A middle-of-the-pack power bill

Next to the median 29–44 pint model, this one costs $18 more to run in the United States over 11 years. That’s how long the DOE expects a portable to last. The thriftiest 29–44 pint model, the Deciuu LIBRA-RCS32(Y)-N4-3(B), would save $101 over those years.

No app to watch it from upstairs

The EPA doesn’t list the VAD35S1AWTS 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 before you buy

Ask for the pump lift and the lowest working temperature

Pump and cold are the two blanks for the VAD35S1AWTS 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.

From the data

Where it stands

At 383 kWh a year, it sits 9 kWh above the middle of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Tied for 72nd of 87 certified 29–44 pint portables for low energy use.
Its efficiency, 2.01 liters per kWh, is 26% above the federal minimum for its capacity class.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.
Vissani also makes it smaller, the VAD25S1AWTS at 27 pints, and bigger, the VDHTL50P at 50 pints.The bigger one uses 143 kWh a year more.
Sold since August 2025. Among 29–44 pint models, 33 of 87 came out earlier.
Not on the EPA’s Most Efficient list, which names 1 of the 29–44 pint models.
The nearest size from another brand is the BLACK+DECKER BDM36WCDA, rated 36 pints and 383 kWh a year.Both cost the same to run in the United States.

in the United States

A day of nonstop drying means 36.39 pints of water, about 4.5 gallons, for some 8.6 kWh. At the average home electricity price in the United States, the VAD35S1AWTS costs $1.57 to run that day.

The EPA’s yearly estimate, 383 kWh, adds up to about 45 days like that. Each extra day at full output costs another $1.57.

Those 36.39 pints come from a DOE test at 65°F and 60% humidity. Cooler air at that humidity gives up less water, so expect fewer pints in a cold basement.

Every day at full output leaves 4.5 gallons to get rid of. Check how the VAD35S1AWTS drains, since our sources don’t say.
