How To - Flooring Options for In-Floor Heating
How to do in-floor heating with the flooring I have/want?

What flooring can I use?
Hydronic Radiant In-Floor Heating can be used with almost any flooring type.
For new construction
it is most common to use slab on grade, putting PEX pipes on top of the insulation, but under the concrete. Doing this allows the cement to serve as a heat sink, creating heat storage for nice even application, and cozy toes and noses.
Here PEX pipes are being laid out on HeatSheet insulation, before cement is laid.
Here we have an example with pink foam board insulation and you can see the cement beginning to be laid.
2nd stories and Wood floors or Retrofits
There are many options for laying PEX pipes with an already existing floor to create in-floor radiant heating in your home or shop.
Gypcrete: Laying PEX down over an existing floor (insulate under it if you want heat to go up and not down), then covering with a layer of gypcrete and using a final layer of anything your heart desires.
In-floor board aluminum heat spreads over the subfloor.
On-Panel or EcoWarm Panels over the subfloor

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.

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.
