Royall's water to air (WAC) heat exchangers are a necessary item when installing your boiler. All boilers need a "dump" zone to exhaust the heat off the boiler when your primary loop is not calling for heat. These heat exchangers are designed to be mounting off the ceiling or the wall of your garage or open floor plans.
This hanging heat exchanger is rated at 200,000 btu, and utilizes a 1" port. This heat exchanger DOES NOT Include a Pump, Fan Control, or Compression Fittings.
