Zehnder Nestsystems radiant conditioning
The principle of radiant heating and cooling can be used in many applications for rooms and buildings.

A system to create a comfortable, healthy and energy-efficient environment

Zehnder Nestsystems radiant conditioning comprise of a network of panels which boast dual heating and cooling functionality, rapid response times, exceptional controllability and superior energy efficiency.

  • Constant room temperature: adapts quickly to fluctuating outside temperatures
  • Reflecting natural conditions: even, draught-free heat distribution
  • The heating and cooling effect immediately noticeable: short response time
  • Silent operation: system does not require fans
  • Better, hygienic climate, also ideal for allergy sufferers: no dust dispersal
  • Comfortable: system does not require maintenance
  • Economic and environmentally friendly: low operating costs, optimised energy efficiency
  • Retains property value: prevents mildew formation
  • Fit for the future: suitable for low temperature systems and heat pumps
  • Space and cost savings: heating and cooling in a single system
  • Quiet and almost invisible: system can be integrated into wall or ceiling
  • More space for individual interior design: no heating or cooling units on the walls

The Zehnder Nestsystems radiant heating and cooling elements are incorporated into a specially designed plasterboard panel which effectively replaces a standard panel within the wall or ceiling and enables it to be fitted as part of the general construction of the building.

How it works

Heating

Cooling

Zehnder Nestsystems panels copy the natural thermal effect of the sun:

The radiant panels are heated by hot water and give off energy into the room. This energy is only converted into a heating effect when it meets the human body or an object.

The radiant panel is the coolest item in the room. Warmer items within in the room heat the air which then passes over the cool surface of the panel and cools down. The cooled airflows back into the room

Plasterboard radiant panels with hydraulic pump, connectors and tubing

The Zehnder Nestsystems panels uniformly placed on the ceiling or wall create a perfect, naturally comfortable climate. The heat or cooling effect is distributed in a balanced manner over the complete area.

Plasterboard radiant panels with hydraulic pump, connectors and tubing PLUS controls

The Zehnder Chronosonda control system automatically determines the optimum water temperature of the system in consideration of internal and external conditions and dew point factors.

Plasterboard radiant panels with hydraulic pump, connectors and tubing with controls PLUS dehumification

The Zehnder Dew dehumidifiers control the humidity of the rooms at 50-55%. This level avoids condensation to form whilst cooling with Zehnder NEST panels.
