Warm NZ - Rehau Underfloor Heating Design Service

The Warm NZ-REHAU underfloor heating design service is used to create a detailed, project-specific plan for installing a hydronic (warm water) radiant heating or cooling system, ensuring it operates efficiently, provides optimal comfort, and complies with all necessary building standards.

This service is a crucial step in both new construction and major renovation projects to avoid costly mistakes and maximize system performance.

Key uses of the service include:

Performance Calculations Qualified heating engineers calculate the required water flow rates and temperatures needed to achieve the desired heat output for each specific space.

Custom Layouts The service provides detailed pipe layout designs, ensuring even heat distribution throughout different rooms and floor types (e.g., concrete slab, timber floors, carpet, tiles).

Material Specification It identifies all necessary REHAU components, including the type and length of PE-Xa pipes, manifolds, and controls, facilitating accurate material estimations and quotes.

Zoning and Control The design incorporates room-by-room zoning, allowing occupants to set different temperatures in various areas for enhanced comfort and energy efficiency.

Documentation The design process produces professional documentation, such as CAD drawings and hydraulic calculations, which can be attached to consent documentation for local authorities.

Integration with Heat Sources The service ensures the underfloor system is compatible with a wide range of energy sources, including gas boilers, heat pumps, solar panels, and geothermal energy, to maximize energy savings.

REHAU provides these tools both through online software for installers and specifiers and via a full service from their technical teams and authorized partners.
