Scope of lesson

This article presents the quick way of designing heating/cooling radiant systems (wet and dry type). The aim of this simple approach to designing is to obtain approximate heat and flow results and to draw up a rough bill of materials.

Modules and program configuration

InstalSystem 5 with the module:

  • Radiant systems.

Project file

The project file used in this lesson: Radiant heating floor and wall system - quick design (example for the lesson).

Inital state

The building structure (storeys, rooms) is defined, plans of storeys are provided. The values of heat load in rooms are specified for heating and cooling.

Steps to perform

The selected steps to perform are included in the basic course of radiant heating and cooling design with loop circuit systems (wet and dry type) and constitute a simplified form of operations described in:

The steps that are included in the articles mentioned above and are not included in this article are optional in the quick design.

Specify catalogues

  1. Catalogues and select catalogues of:
    • Radiant systems
    • Pipes and pipe fittings

Specify general data

  1. Project scope and select range:
    • Heating systems
    • Cooling systems
  2. Building and surroundings
    • Climatic data - select Town
  3. Thermal systems - append information for:
    • Distribution system
      • Virtual connections of radiant systems - check that Create virtual connections when there are no graphical connections is enabled
      • Types and default data
    • Radiant systems
      • Floor systems
      • Wall systems
      • Manifolds, fittings and control
      • set Coils and Method of R.H. material listing to

Edit installation - radiant system

Heating/Cooling Zone

  1. Insert Heating/Cooling Zones into rooms using the Floor (in each room) function. Repeat the operation for each storey. Insert Wall (manual) in selected rooms.

Manifold

  1. Place manifolds in approximately defined locations.


Calculations and diagnostics

Verification of results

  1. Verify calculation results, diagnostics and bills of materials paying special attention to:
    • List of radiant heating components for all the key components of the system.
