NDW Water-to-Water
A New Standard in Performance
The Envision NDW Series 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 NDW Series. With skyrocketing costs of fossil fuels, savings potential will only increase.
Radiant Floor Heating- Experience luxurious comfort throughout the room from head to toe. Floors are kept toasty warm, even on the coldest days.
Domestic Hot Water- Homes with large demands for domestic or portable water heating will benefit from the exceptional efficiency of NDW units. When used in conjunction with another WaterFurnace Geothermal unit to condition the air inside the home, the complete system provides the ultimate in savings, comfort, and safe, reliable, quiet performance.
Pool Heating- NDW units can also be utilized to hear water for pools and spas for much less than an ordinary pool heater.*
Snow & Ice Melt- Keep your sidewalks or driveway free of ice and snow during the cold winter months. Eliminate the hazards of walking on ice-covered side walks, and reduce the need to shovel snow.
The NDW Series Design:
Envision NDW Series products are designed to meet the high-volume water demands of today’s larger luxury homes. NDW units provide high capacity heating and cooling performance, but still deliver the features homeowners have come to expect from our Envision line.
- Cabinet: The NDW unit cabinet is fabricated from heavy gauge steel and a durable metallic finish for long lasting beauty and protection. A swing out control box and control panels that can be placed on either end (allowing piping to be located on the front or at the back) improved serviceability.
- Controls: A microprocessor controls the load pump, source pump and compressor by sampling tank temperatures within the GeoTank (see back page) A robust controller enables the user to view all modes of operation and easily adjust temperatures. All fault conditions are monitored by the controller to ensure safe, reliable operation. Although sophisticated in its operation of the unit, the control is easy to adjust using a single mode button, up/down arrows for temperature setting, and an LCD screen which displays current temperature and settings.
- Soft Start: IntelliStart™ reduces the amount of current needed to activate the unit by 70%. This helps alleviate light flicker, reduces start-up noise and increases compressor life. For those with self-sufficient homes, IntelliStart™ allows WaterFurnace units to run off-the-grid.
- Brazed Plate Heat Exchangers: Brazed plate heat exchangers provide increased efficiency, performance, and reliability. Because they’re much smaller than traditional coaxial exchangers, they allow NDW Series units to provide high capacity performance in a compact unit.
- Compressor: Two high efficiency scroll compressors keep operating costs low and will provide years of reliable operation. Sound attenuating compressor blankets and double-isolation mounting plates are used in every unit for “whisper-quiet” operation.
Factory Quality: Stringent standards ensure NDW units include only the finest components, and are assembled according to detailed quality control procedures by skilled technicians. Each unit is computer run-tested to ensure proper performance.
R-410A: Environmentally friendly R-410A refrigerant is used in all NDW units.
AHRI/ETL Listed: WaterFurnace NDW Series units are performance tested in accordance to the AHRI, and safety listed by ETL. Energy Star doesn’t currently recognize water to water hydronic units.
The Hydro tank controller accessory is made to be used in conjunction with our GeoTank. It adds advanced features like Outdoor Reset (sampling outdoor temperatures to better regulate tank conditions) and Unit Staging (sequencing multiple units for peak performance that save energy and money.
