The Envision Series NDW

Forced air
Envision NDW Dual Stage Hydronic

The Envision Series is the precursor to our 5 Series and is tried and true. The NDW dual hydronic features two single-stage compressors to provide high volume hot water for the needs of today's larger luxury homes.

Keep your feet warm
Exceptional Comfort Keep your feet warm

Many Envision NDW owners use their unit to provide hot water for radiant heat. These systems offer exceptional comfort without moving air. Not only is the floor kept toasty warm, but the entire floor radiates heat to the occupants, furnishings and the air.

Water to water
Luxurious hot water High performance

Homes with large demands for domestic or potable water heating will benefit from the exceptional efficiency of NDW units and will realize savings by as much as 60% per year when replacing an ordinary boiler or water heating system.

Dedicated hot water
Pool & spa heating

The NDW is perfect for ultra-efficient pool and spa heating. It uses the heat from the earth to keep your pool and spa nice and warm year-round and is much more cost effective than an ordinary pool heater. (Note: Secondary heat exchanger required)

Cost per million BTUs of hot water
New standard in performance

The Envision NDW can reduce water heating costs by as much as 60% per year. Ordinary boilers and water heaters operate at a fraction of the efficiency of the 5 Series. With skyrocketing costs of fossil fuels, savings potential will only increase.

Keep your sidewalks and driveway free of ice and snow during the cold winter months by using the NDW. The system circulates hot water beneath the concrete or pavement to eliminate the hazards of walking on ice-covered sidewalks and reduces the need to shovel snow.

Other NDW Features
GeoTank
Brazed Plate Heat Exchanger

Brazed plate heat exchangers provide increased efficiency, performance, and reliability. Because they're much smaller than traditional coaxial exchangers, they allow high capacity performance in a compact unit.

Dual compressors
Compressors

Two high efficiency scroll compressors keep operating costs low and will provide will provide years of reliable operation. Sound attenuating compressor blankets and double isolation mounted plates are used in every unit for quiet operation.

IntelliStart
IntelliStart

This optional soft starter reduces start-up amperage by 60% of normal draw to reduce noise, eliminate light flicker, and increase compressor life.
