Matching heating panels, pipes & floor finishes

A pipe that fits into a groove is only the first compatibility check. The heating design must also suit the room demand, circuit layout and floor covering, while the finished construction needs suitable support and permitted layer materials. Make these checks together rather than selecting each component independently.

Pipe diameter and pipe spacing are different numbers

A 16 mm pipe reference describes the pipe outside diameter; it does not specify the distance between runs. The groove or retention feature must fit the pipe, while spacing belongs to the heating layout. Both numbers should appear in an enquiry, together with the panel model and a section through the finished floor.

Published dry systems show why one generic panel rule fails

Uponor’s Tignum system uses grooved chipboard, thin aluminium heat-emission plates and a specified 17 mm pipe. Its Siccus 12 mm information describes grooves for 12 × 1.7 mm pipe at 125 mm centres. These are named external examples, not Banarta specifications or interchangeable components.

Even within dry construction, the panel material, pipe and layout can differ. “Dry underfloor heating board” therefore does not establish pipe compatibility or permit substituting a 16 mm pipe into either example.

Use the correct product route for the design

After choosing the format, add every layer in the floor-height calculation and combine covering plus underlay resistance using the thermal-resistance guide. A finish change needs both checks even when the pipe and panel are unchanged.

Coordinate three documents

Use the same room references across all three. If a floor finish changes, tell the heating designer as well as the flooring contractor. The change may affect heat transfer, total depth or installation requirements even when the panel order remains unchanged.

Check the actual pipe and profile

Specify the pipe outside diameter and the selected panel model. Confirm straight-run fit, bends, return zones and transitions to the manifold. Ask for the panel’s permitted configuration; do not force an incompatible pipe into a profile or assume a generic routing pattern will fit the final circuit drawing.

Compare the panel formats in the demonstrations

These two Banarta NJ videos show different ways of locating heating pipes. Use them to identify the format you want to discuss, then check the supplied model against your drawing.

• Aluminium-grooved XPS panel demonstration: the close-up shows a silver-coloured facing, exposed foam edges and preformed channels. Ask for the channel drawing, pipe outside diameter, spacing and return arrangement for the quoted panel.
• Modular EPS heating-panel demonstration: the installation footage shows orange studded panels being laid across a room and pipe routed between the raised studs. Ask for the model-specific pipe range, panel connection detail and usable coverage after joining.

A demonstration does not establish the permitted finished floor. Request a section showing the supporting base, heating panel, any screed or load-distribution layer, adhesive or underlay, and final covering. A general video description about laying tiles or timber directly over a panel is not approval for your selected assembly.

When enquiring, include the video link, the feature you mean and your floor drawing. We can then discuss the corresponding XPS or EPS panel configuration without treating every product shown as the same model.

Let the design determine spacing and output

Pipe spacing and circuit details should follow the heating calculation. The floor covering is part of that calculation: its thermal resistance and temperature limits matter. Uponor’s floor-covering guidance highlights these checks; use the chosen system and flooring manufacturers’ data for the actual design. This guide does not assign a universal spacing or heat-output figure.

Do not skip the covering-layer decision

Do not assume tiles, timber or another finish can be laid directly on every aluminium-faced or studded panel. Obtain the full permitted floor build-up, including any load-distribution, preparation and bonding requirements. Confirm that the complete depth works at thresholds and adjoining rooms.

For a tiled water-heating floor, compare cement-coated grooved XPS tiling and overlay options before deciding whether the quoted package includes a separate covering layer.

Checks before the floor is covered

• Match the installed panel and pipe references to the approved design.
• Verify that routes and return zones follow the layout.
• Complete the tests required by the selected heating-system instructions and keep the results.
• Photograph pipe routes before concealment.
• Agree the curing, commissioning and initial heating procedure with the relevant suppliers.

For a panel enquiry, send the circuit drawing and the full floor section with the finish identified. Compare 1500 × 600 mm XPS hydronic heating board with the required configuration. Product selection should support the heating design, not substitute for it.
