Sewage-to-Water-or-Domestic-Water Heat Pumps for Water Heating

Sewage-to-water-or-domestic-water heat pumps gather heat from wastewater and deposit it into water at a usable temperature for water heating.

Details include:

  • Every day, a tremendous amount of hot water is used once before ultimately being discarded down the drain
  • In the U.S. alone, 350+ billion kilowatt hours of energy are added annually to domestic potable water between point of building intake and exit (U.S. Department of Energy)
  • Wastewater energy recovery technology captures and reuses the nearly limitless supply of wastewater’s thermal energy
  • This provides sustainable heating, cooling and conditioning for many building types
  • Wastewater energy recovery is the last line of defense for energy recovery


SHARC Series

  • Industrial-sized wastewater heat recovery and filtration
  • Filters large volumes of wastewater to provide energy to heat, cool and meet hot water demands
  • Using patent-pending filtration, the SHARC is designed to handle higher volumes of wastewater
  • It can seamlessly fit into just about any condenser water system, and it provides a more optimal temperature range for increased system efficiency
  • Applications: large commercial, mixed-use, industrial
SHARC System

Key features:

  • Patent-pending, high-efficiency filtration system
  • Sizes range from 6 to 12 inch piping (100 to 1,600 GPM)
  • Chain units together to suit larger flow rates
  • Pair with a heat pump to amplify heat transfer
  • DDC control system with touch screen control, remote monitoring, data trending and email alerts (Modbus standard and BACnet integration available)
  • Temperature sensors, pressure sensors and flow meters are included
  • Automated reversing valves control back flush, keeping the heat exchanger operating at design parameters


  • All-in-one with heating and cooling
  • The PIRANHA Series is a packaged heat pump water heater that uses raw wastewater as the thermal energy source
  • As the SHARC Series’ smaller cousin, the PIRANHA Series is an all-in-one powerhouse that can perform simultaneous heating and cooling
  • Applications: mixed commercial/residential, multifamily, hotel and hospitality, breweries, community activity centers, hospitals

Key features:

  • Simultaneous heating and cooling utilizing wastewater
  • Efficiencies as high as 800%
  • All-in-one unit, includes custom heat exchanger
  • Can chain multiple units together
  • Remotely monitored and managed
  • Quiet operation
  • Odor-free
  • Optimized for multifamily residential and commercial applications
