This on-site installation service utilizes blue PEX pipes specifically designed for heating systems; these pipes are corrosion-resistant and withstand extreme temperatures, featuring smooth inner walls that minimize water circulation resistance. The system includes grid-patterned insulation/reflective film, plastic fixing clips, and perimeter expansion insulation strips, with pipe layouts customized to room dimensions. The installation process covers the entire workflow: floor preparation, insulation layer laying, pipe securing, circuit connection, and hydrostatic pressure testing. We strictly control pipe-bending techniques to prevent kinking and minimize the number of joints. Pipeline pressure is monitored throughout the installation to ensure a leak-proof seal. Suitable for various unfinished interior spaces, the system allows for mortar backfilling after installation, providing uniform radiant heat without drafts or excessive dryness, creating a gentle and comfortable underfloor heating environment.
