Top 10 Best Underfloor Heating Design Software of 2026

Wavin Sentio Design Software is built around an underfloor heating design workflow that links room-by-room loads to selectable circuits and then carries those results into installation documentation. The tool produces design outputs that include circuit and manifold-related information used during commissioning planning, including flow and return intent for each zone. It also supports configuration of pipe and system parameters so the design can be regenerated when layout assumptions change.

A key tradeoff is that Sentio’s strongest automation is tied to Wavin system configuration, so engineers who need fully vendor-neutral hydraulic balancing inputs may spend more time aligning assumptions. It fits best when an engineer manages many similar projects and needs consistent circuit layouts, hydraulic results, and documentation in one regeneration loop rather than spreadsheet handoffs.

Watts Radiant UponWorks is used to create underfloor heating designs that combine emitter circuit layouts with component selection tied to Watts radiant systems. It handles project setup steps such as heat emitter sizing and zoning decisions, then carries those choices into schedules and documentation outputs for downstream review. Cad and BIM coordination depend on the import and export paths available in the installed workflow, so teams that already standardize on Revit or IFC should validate format compatibility early.

A notable tradeoff is that the depth of automation depends on whether the project is managed inside Watts product constraints rather than as a fully generic radiant design engine. It fits best for teams producing many Watts-based jobs who need consistent manifold zoning and documentation output with fewer manual recalculations between design revisions. It is less efficient for projects that require mixing large volumes of non-Watts components or unusual commissioning protocols not covered by the built-in workflow.

Raulinx is aimed at heating designers who need circuit generation, room-by-room load inputs, and hydraulic results that stay aligned with REHAU system configurations. The tool produces outputs used for manifold and circuit documentation, including design flow rates and loop-level checks that support planning for pressure testing and balancing workflows. It also helps with planning around heat loss envelopes and thermal performance so the design basis is not scattered across separate spreadsheets.

A tradeoff appears when projects require cross-vendor component mixes or non-REHAU emitter assumptions, because the strongest automation tends to follow REHAU catalog data and configuration rules. Raulinx fits best when a designer has REHAU-centric specifications and needs repeatable circuit layouts that remain consistent from design through installer documentation.

Plastic Pipe Institute PPI BCD is a design-focused underfloor heating resource from plasticpipe.org that emphasizes compliance-oriented calculation workflows rather than generic CAD drafting. Core capabilities center on deriving circuit layouts and supporting hydraulic and thermal sizing steps that feed into BS EN 1264 style deliverables for radiant slab design.

The workflow is geared toward using standardized component assumptions for pipe routing, manifold zoning, and emitter output checks across rooms. Integration options are limited compared with BIM-first engineering tools, so output reuse depends more on document export formats than deep model coordination.

Polysun focuses on underfloor heating design work that starts with room loads and ends with circuit and manifold specifications.

The tool’s radiant slab simulation workflow connects floor thermodynamics inputs to room-level outputs used for design verification.

Circuit layout generation uses hydraulic constraints so designers can adjust zoning without redrawing every circuit manually.

Interoperability features target CAD and model coordination so downstream plan sets and exchanges match the calculated design.

MagiCAD for Revit targets underfloor heating and hydronic design directly inside Autodesk Revit, with automation that ties calculation inputs to BIM elements. It supports room-by-room heat load work, circuit and pipe layout generation, and schedule outputs that keep Revit documentation and calculations aligned.

Revit coordination is a core workflow point, including CAD plan import for building geometry capture and IFC export for downstream exchange. The overall result is a Revit-first design cycle that focuses on generating and maintaining the emitter and hydraulic information within the same model.

Solar-Computer focuses on underfloor heating design by connecting circuit layout decisions to sizing and manifold planning outputs.

The workflow supports iterative updates for typical design revisions while keeping related calculations aligned across the same drawing set.

Plan import and documentation exports support review cycles, but BIM coordination depth is narrower than tools built around Revit or IFC-centric coordination.

Elite Software Rhvac targets underfloor heating design workflows with circuit and zone layout, room-by-room heat loss inputs, and radiator style reporting for commissioning packs. It produces design outputs tied to practical installation documents, including schedules for pipe and manifold elements and exportable plan views for downstream detailing.

The software is distinctive for mixing hydraulic and thermal calculation outputs with drafting-friendly documentation steps rather than isolating calculations in a spreadsheet-only flow. It also fits teams that need repeatable project templates, since recurring design settings can be reused across jobs for consistent documentation.

Purmo Planner is an underfloor heating design workflow focused on building heat emitter layouts, pipe circuits, and manifold concepts tied to Purmo components. The core capability centers on room-by-room configuration that produces circuit-level outputs engineers use for hydraulic and installation planning.

Document handoff is supported through export options that fit common CAD and documentation steps for heating projects. The design process emphasizes standards-style inputs such as emitter selection, circuit grouping, and zoned system structure rather than open-ended modeling.

Hottgenroth ETU Planer targets heating engineers who need underfloor heating project planning in a rules-driven workflow tied to installer deliverables. It focuses on circuit planning, emitter and manifold calculation outputs, and compliance-oriented documentation that stays aligned with typical radiator and radiant slab design conventions.

The software also supports CAD plan import for room layouts and can produce project documentation sets for construction handoff. In practice, it fits teams that value repeatable design calculation steps over open-ended experimentation.
