Bi-Yearly Maintenance for HUG Hydronics Systems with Antifreeze

Video Coming Soon!

Check your Glycol bi-yearly by using a pH test strip. Just dip it into the liquid in the tank, Read it by comparing the color to the chart with the test strips.

The pH level should range between 8.0 and 10.0.

Any fluid with a pH below 7.0 should be replaced. 


For fluids between 7.0 and 8.0, adjustments can be made using a 50 percent solution of sodium hydroxide or potassium hydroxide. HUG Hydronics will soon offer pH adjustment kits for quick and easy use.

Every 3-5 years the glycol degrades enough that it will have to be completely replaced. You will know it is time if the pH is lower than 7.

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.
