Ground Source Heat Pumps

Founded in 1980, Waterfurnace international’s headquarters and manufacturing facility is located in Indiana, USA. FG Renewables have been using Waterfurnace heat pumps since the company started in 2006 and have over 200 machines installed in Northern Ireland.

The machines are very efficient and reliable and we here at FG Renewables know the machines inside out.

Features

  • Designed to operate with entering source water temperature of -1°C to 43°C.
  • Heated or chilled water from the same machine
  • Modularized design for optimum capacity matching and staging.
  • Stackable for space conservation.
  • Water heating to 55C
  • Water chilling to -12C
  • High cooling and heating COPs.

 

The NSKW Series Design

Envision NSKW Series products are designed to combine the comfort and versatile installation associated with heating and cooling, with the technology and efficiently associated with our Envision line.

CONTROLS: A microprocessor controls the load pump, source pump and compressor. 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 a LCD screen which displays current temperature and settings.

INSULATED COAXIAL HEAT EXCHANGER: NSKW heat exchangers are coated with our exclusive ThermaShield™ foam insulation. ThermaShield takes the place of traditional taping and increases both efficiently and consistency of our heat exchangers. Robotic application ensures an even, airtight seal, while the WaterFurnace names ensures it’s environmentally safe.

COMPRESSOR: High efficiently scroll compressors are used to reduce operating costs and provide years of reliable operation. Sound attenuating compressor blankets and double-isolation mounting plates are used in every unit for quiet operation.

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

FACTORY QUALITY: Stringent standards ensure NSKW 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 NSW units.
