HUG Hydronics In-Floor Heating System Components

HUG Hydronics replaces a traditional wall of plumbing with one no-pressure tank, a set of pumps, and simple push-on PEX connections. Every system starts with the HUG Hydronics Tank — the core unit that houses the pumps and controls. From there, you add the specific components your setup needs: a heat source kit that matches your boiler or water heater, pump kits for additional zones, and dividers or splitters for more complex layouts.

FAQ:

  • Do I need the Tank if I already have a boiler or water heater?

    Yes — the Tank is the core of every HUG Hydronics system regardless of your heat source. You'll also need a heat source kit that matches your specific boiler or water heater type to connect it to the Tank.

  • What's the difference between the Standard and Large Heat Source Pump Kit?

    The Standard kit is sized for most on-demand water heaters. The Large kit is built for higher-output boilers that need more pump flow. [Link: heat source pump kit comparison / spec sheets]

  • What does the Plate Exchanger Heat Source Kit require?

    It's designed for pressurized boiler systems and requires an additional kit to complete the connection. Navien or Rinnai plumbing kit to work with it. 

    If you're not sure which heat source setup applies to you, use the Wizard or call us at 218-587-5001.
