Light Duty Commercial Heat Pump Water Heaters

  • Light duty heat pumps can be used for small commercial or residential facilities that have some hot water demand. These typically have a tank with up to 50 gallon storage capacity. 
  • Tens of thousands of Mainers own these heat pump water heaters. They’re popular because they produce lots of hot water, can save more than $500 per year in electricity*, and help to dehumidify. 

*Compared to a traditional electric water heater. Your cost and savings may vary.

Heavy Duty Commercial Heat Pump Water Heaters

  • Heavy duty commercial heat pump water heaters can offer hot water needs for commercial settings, including hospitals, hotels, motels, multifamily buildings, long-term care facilities, and offices. 
  • Heavy duty commercial heat pump water heaters can come in sizes that range from 80 to 120 gallons. 

ECM Circulator Pumps

  • Businesses can reduce electric costs with the installation of ECM circulator pumps. Forced hot water (“hydronic”) heating systems use circulator pumps to move heated water from boilers to radiators and back. These pumps run whenever a thermostat calls for heat. Pumps have a spinning shaft called a rotor that is rotated by a magnetic field created by coils of wire that surround it. The spinning rotor circulates water through the boiler distribution system.
    Traditional circulator pumps run at one fixed speed and use some electricity to magnetize their rotor. Electronically commutated motor (ECM) circulator pumps can modulate their speed and use permanent magnet motors that don’t require any electricity to have magnetic properties. ECM circulator pumps cost less to buy and less to operate than traditional circulator pumps.
