Uponor Siccus 16 direct-tile dry radiant floor heating system for 40% faster installation

In addition, its low installation height of just 20 mm and lightweight construction make it a real solution for the renovation sector where installers often face three major challenges: limited installation height, complex assembly and floor load restrictions. Uponor Siccus 16 delivers optimal heating performance in around twenty minutes and is ideal for low-temperature heat sources such as heat pumps.

As Europe prioritizes energy-efficient renovations over new construction, the construction industry faces numerous challenges in modernizing existing buildings while maintaining structural integrity and meeting modern energy guidelines. Traditional underfloor heating systems require thick screeds, increasing installation height, structural load, and installation time—all of which complicate system upgrades. The demand to upgrade and extend the lifespan of existing buildings requires better solutions. The Uponor Siccus 16 dry radiant underfloor heating system was designed to overcome these challenges. By enabling direct installation of the floor covering, this system eliminates the need for unnecessary layers, reduces installation height, simplifies assembly, and reduces installation time by up to 40% by eliminating installation steps. Its lightweight construction ensures compatibility with floor load restrictions, making it ideal for renovation projects.

Radiant heating reinvented

Where previously underfloor heating was not an option due to structural conditions, the new Uponor Siccus 16 dry radiant heating system offers this possibility thanks to its extremely low installation height of just 20 millimeters (28 to 38 mm total floor height depending on the final floor covering) and its light weight (2,5 kg/m2 including pipes). "This innovation enables our specialist partners in the planning and sanitary installation sector to further expand their range of offerings in renovation projects. "They can now also undertake renovation projects that previously could not be modernized energy-efficiently with underfloor heating due to technical circumstances," said Torsten Meier, Chief Innovation Officer, GF Building Flow Solutions.

Quick installation saving multiple steps

The Uponor Siccus 16 underfloor heating solution can be installed dry without heavy, high-moisture screed, significantly reducing construction costs. Another advantage of the system: technicians can install the underfloor heating themselves (installation requires only one person) and without interruption. This makes the system installation up to 16% faster, which also reduces costs. Simplified assembly provides greater safety, as fewer work steps also mean fewer sources of error, and Uponor Siccus 40 therefore offers a highly efficient and low-risk panel heating installation.

Comfort factor: reach the desired comfort temperature more quickly

Radiant heating and cooling provide a high level of comfort. Uponor Siccus 16 underfloor heating ensures comfortable temperatures all year round. Because underfloor heating produces radiant heat, it is distributed evenly throughout the room. This ensures reduced drafts compared to radiators or conventional ventilation systems. Thanks to its proximity to the surface, optimal heating performance can be achieved in about twenty minutes.

Cooling is the new heating

The Uponor Siccus 16 panel heating system is an energy-efficient cooling solution thanks to its compatibility with heat pumps, which can also be used for cooling. Energy-efficient cooling solutions, combined with high comfort, are increasingly in demand due to climate change. Anticipating this development offers new business opportunities for installers. Uponor Siccus 16 is an efficient and universally applicable solution for a comfortable climate all year round.

Design freedom factor: room design without radiators

Uponor Siccus 16 offers planners and building owners more design options in the room: the heating is fully integrated into the floor, so the interior design does not require adaptation to the heating system with traditional radiators, which take up space on the walls. "This is another major advantage of underfloor heating systems over traditional radiators: they require regular maintenance and cleaning to ensure proper operation and have a significantly shorter lifespan of 20 to 30 years. "Because underfloor heating systems operate at low temperatures and low pressure, they can operate smoothly for around 40 to 50 years if used properly," explained Torsten Meier. "It's not only a cost-effective solution, it's also sustainable."

Uponor Siccus 16 technical properties:

• Lightweight and compact panel with integrated heat distribution made of aluminum for dry construction
