Underfloor (Radiant) Heating Design, Automated

Underfloor / Radiant Heating Design

No more manual trial-and-error on loop spacing and heat load

Stop hand-drawing transit pipe routes back to the manifold

Instantly split large floor plans into valid, balanced loops

Smart warnings that tell you exactly what's wrong and how to fix it

"The software [h2x] automatically calculates the length of each circuit from the manifold to the designated room, allowing us to ensure all pipe runs remain within our design threshold."

The Smarter Way to Design Underfloor (Radiant) Heating Systems

h2x software replaces the manual trial-and-error of traditional underfloor / radiant floor heating design with powerful automation and intelligent warnings.

Whether you're working on a simple room or a complex multi-zone floor plan, h2x gets you to a finished design faster.

Heat Loss / Load Calculations

Upload your plans, trace around room outlines, and h2x will automatically calculate the heat requirements based on your specified materials, temperatures, and air changes. This forms the basis for your system, ensuring it will be accurately sized.

Underfloor / Radiant Heating Design Heat Load Calculations

System Layout & Sizing

In just one click, generate loops with automated sizing. The calculations are based on various options such as the floor finish, water temperature, and preferred loop pattern. Results integrate seamlessly with drawings and reports, updating instantly whenever design changes are made.
