RADIANT / UNDERFLOOR HEATING

Comfort From
the Surface Up.

Radiant heating approaches thermal comfort differently — using carefully engineered floor or surface systems to transfer heat into occupied spaces.

RADIANT SYSTEM THERMAL COMFORT
THERMAL ZONE RADIANT COMFORT

Heating Through
Radiant Energy Transfer.

Radiant heating systems deliver heat through surfaces rather than relying exclusively on conventional air movement. Underfloor systems are one way of implementing this approach.

The engineering requirement goes beyond the floor installation. Heat load, surface temperature, zoning, heat source, controls and building construction all influence the system design.

APPLICATIONS

Where Radiant Heating
Can Make Sense.

Radiant systems can be considered where thermal comfort, floor-area utilization, building characteristics and the selected heat source support the engineering approach.

01

Residential Buildings

Surface-based heating for homes where comfort, zoning and system integration are important design considerations.

02

Large Halls

Radiant floor strategies for large occupied spaces where conventional air-heating approaches may require careful engineering evaluation.

03

Cold-Climate Buildings

Heating strategies for buildings where maintaining thermal comfort during cold conditions is a major requirement.

04

Specialised Spaces

Custom applications where the building form, occupancy and heat-source strategy support radiant heating.

ENGINEERING SCOPE

Designing the System
Behind the Surface.

A radiant system must be designed around the building's thermal requirement and the characteristics of the selected heat-transfer system.

01

Heat-Load Assessment

Establishing the building heating requirement before determining the appropriate radiant system strategy.

02

Surface Strategy

Evaluating floor or other radiant surfaces in relation to room use, construction and required thermal comfort.

03

Heat-Source Integration

Coordinating the radiant distribution system with the selected heating source and overall HVAC strategy.

04

Zone Planning

Dividing the system into appropriate thermal zones based on occupancy, space use and control requirements.

05

Controls

Considering temperature sensing, zone control and operating strategy as part of the complete system.

06

System Coordination

Integrating radiant heating with the building, insulation, HVAC and other services involved in the project.

ENGINEERING CONSIDERATION

Different Heat Transfer.
Different Design Thinking.

Radiant heating and conventional air-based heating approach thermal comfort through different heat-transfer mechanisms.

The right choice depends on the building, climate, heat load, occupancy, heat source and project objectives. Radiant heating should therefore be evaluated as part of the complete HVAC strategy.

01
Heat Transfer

Surface-based radiant heat transfer versus predominantly air-based heat distribution.

02
Space Planning

The distribution method interacts directly with the architecture and occupied space.

03
Control Strategy

Thermal zoning and surface response need to be considered during system design.

04
Building Envelope

Insulation and building characteristics remain important factors in the overall heating requirement.

RADIANT DISTRIBUTION
GEOTHERMAL INTEGRATION

Radiant Systems Can Work
With Sustainable Heat Sources.

Radiant distribution can be considered alongside geothermal and other suitable heat-source strategies when the building requirement and system design support the combination.

This creates an opportunity to evaluate the heat source, distribution method and building demand as one integrated engineering system.

DESIGN & OPTIMIZATION

Comfort Begins
With the Right Analysis.

Radiant heating should be sized and configured according to the actual thermal requirement rather than treated as a standalone floor installation.

Our engineering approach considers the building, heat load, surface strategy, heat source and controls together.

Building Assessment

Understand the construction, occupancy and thermal characteristics of the space.

Heat Requirement

Establish the heating demand before developing the distribution strategy.

System Integration

Coordinate the radiant system with the selected heat source and other HVAC requirements.

Zone Control

Develop appropriate control considerations for different thermal zones.

ENGINEERING EXPERIENCE
