How To - Add a Heater Pump
How to Add a Heater Pump
When in doubt, add a clamp for a secure connection.
2. Connect the blue end of the blue hose with the white pipe to the return side of the warm water side of of the heat source.
3. Run the unconnected end of the blue ended hose into the top of the tank through the first open hole on the right side of the tank.
4. Stick the white pipe end of the other blue hose into a hole on the left side of the tank.
Push it into the tank until it will go no further. If needed, move the other hoses to the right a hole or two to make room for the heater hoses from the additional heat source(s).
5. Connect this blue hose in the tank to the pump.
Slide it all the way on to the pump’s hose attachment.
6. Install the pump.
Install, (or reinstall) pump 9 (& 8 if adding 2 additional heat sources) so the long nose tip go through the hole in the back side of the tank, just like pump 10.
If it doesn't want to sit well, pull on the blue hose it is attached to until it cooperates.
If you didn’t purchase your HUG Hydronics system with enough pumps, you may order another pump for each additional heat source you plan to add.
7. Slide the box on the pump cord into its groove below the control board.
Just below the control board are the grooves for the box on the pump cord.
Slide the box in from the top until the bottom is securely in place and then use the thumb screw to screw it in place on its top right side.
8. Plug the pump into the white pump plug on its section of the control board.
The holes between the pump cord boxes and the control board can be used to pull any excess wire through.
9. Open the control board and locate the pump control sections for 8 & 9
Put a jumper on the pins labeled “heat source” for each additional heat source you’ll use. (#10 is already a heat source).
Set your pump speed as desired.
Put a jumper on all zones you want it to heat for.
10. Purge the Pump.
If the HUG Hydronics System has been turned off, turn on it on by using the switch on the power supply.
On the control board, put a jumper on the “purge” pin for the new pump. The air will move out and the water into the loop.
It is done when the gurgling sound ends.
Remove the jumper from the “purge” pin.
11. Add water to the tank as needed to reach the “full” level, about 3 gallons per loop.
Close the tank and lock the lid into place.
Turn on your heat source when you are ready to use it.
What's Happening in Cottonwood?
Extreme Panel's demonstration house brings building techniques into the real world. As a sponsor, HUG Hydronics is providing Heat-Sheet, PEX, and the in-floor heating distribution system for the project.
Fellow EP Summit sponsor BUILD Show Network is documenting the process with cameras, interviews, and a closer look at each step of the process, leading up to the January 2027 Summit.
See the build come together.
Take a closer look at the project, then explore what radiant in-floor heating could look like in your own home, shop, or garage.

What HUG Hydronics Brings to the Project.
- Start below the slab
- Heat-Sheet insulation provides the foundation for the project's radiant floor.
- Put warmth underfoot
- PEX loops carry heated fluid through the floor, turning the slab into part of the heating system.
- Bring it together with HUG Hydronics
- The HUG Hydronics system brings pumps and controls into a compact system simplifying the mechanical setup that serves the floor.
No. The Wizard is designed to walk you through the basics in plain language. Homeowners and building professionals can use it to explore what their project may need.
HUG Hydronics is sponsoring Extreme Panel's project by providing its in-floor heating materials and system. BUILD Show Network is a fellow EP Summit sponsor documenting the demonstration house. The summit is planned for January 2027.
Yes. Call HUG Hydronics at 218-587-5001 or email sales@hugllc.com. Additionally, completing the HUG Wizard is a useful first step toward discussing your program.
Nope, and we love Extreme Panel's way of building, however this project showcases only one type of application of HUG's system. HUG Hydronics can also be used in other homes, shops, garages, and ag buildings where radiant floor heating is appropriate.
Have your floor plan or approximate dimensions handy, along with basic details about your insulation, ceiling heights, and windows. Think about which spaces you'd like to control with separate thermostats. The Wizard will guide you through the planning process, and HUG's team can help review your project's needs.
