Scope of lesson
This article presents the method of designing radiant heating systems in loop arrangements (dry and wet).
The example shown is based on a design for a single-family two-storey house with no basement.
Modules and program configuration
The InstalSystem 5 includes the following module:
- Radiant systems.
Inital state
The project includes a complete set of default data defined in a template.
The rooms arangement was based on base drawings in DWG format. More details in: Table of project example.
Steps to perform
Open new project file
- Launch InstalSystem 5.
- Open a new project and choose the preferred file version.
For more information, see: Project and application management - Select the appropriate template.
For more information, see: Template files
Define catalogues and general data
Declare General data in default data:
- Storeys management - add the required number of storeys
For more information, see: Preparation of building structure - Catalogues - choose catalogues according to the list in the Project table with regard to:
- Radiant systems
- Pipes and pipe fittings
- Insulation
- Valves and fittings
- Thermal systems - append information for:
- Distribution system
- Types and default data
- Radiant systems
- Floor systems
- Wall systems
- Manifolds, fittings and control
- Distribution system

Prepare building structure
- Import, rescale and arrange in relation to each other, by inserting Reference point, base drawings for each storey.
For more information, see: Import files - Redraw rooms in the rescaled base drawing using the AUTO mode.
For more information, see: Insert rooms - Automatically number the rooms using the Symbols assignment function. Start from the room in the upper left corner of each storey.
- Make appropriate corrections in Data table:
- Design temperature: enter 24°C for bathrooms, 16°C for lobby.
- Maximum permissible floor surface temperature by selecting appropriate room type in the Heating section.
- For unheated rooms, specify the value of heat loss index as "0".
For more information, see: Setting up the building structure
- Verify the correctness of the structure entered in 3D view.
For more information, see: Preparation of building structure
Edit installation - radiant system
Heating/Cooling Zone
- Insert Heating/Cooling Zone components in selected rooms.
- Cut out appropriate fragments of: Heating/Cooling Zone and/or change their shapes to adapt them to occupied areas (stairs, bathtubs) in rooms.
- Divide selected areas of Heating/Cooling Zone with regard to required expansion allowances.
- Declare and set up the Peripheral zone (PZ).
For more information, see: Dividing a Heating/Cooling Zone
Manifold
- Insert Manifold on every storey. Manifold is inserted in the drawing together with manifold cabinet.
For more information, see: Manifold and accessories
Pipe feeds route
- Connect Heating/Cooling Zone with manifolds using Pipe feeds route. Pipe feeds route enables automatic generation of pipe feeds.
For more information, see: Editing pipe feeds in a radiant system
Edit installation - feed to manifolds
Source
- Insert Source on the lowermost storey.
Riser
- Insert Riser, assign a symbol to it and define its extent (from storey 0 to storey 1).
For more information, see: Connecting storeys with the "Stack" element
Distribution
- Connect Source, Manifold, Riser with each other by drawing the network using the Pipe-run component and the AUTO and ORTO modes.
Fittings
- Insert Valve onto pipe-runs.
- Select Valve type in Data table.
- Use Copy - Paste to insert fittings of the same type onto other pipe-runs.
Verify correctness of installation structure
- Verify the correctness of the installation structure using the Check connections function (Key shortcut: Shift + F2).
- Verify the correctness of the installation structure and find conflicts using 3D view.
For more information, see: Verification of the correctness of installation structure
Edit installation components data
Covering
- Mark selected Heating/Cooling Zone components and specify the type of Covering.
Heating/Cooling Zone
- Mark these Heating/Cooling Zones where significant surface area is occupied by pipe feeds and change their type to Heated/cooled by pipe feeds. Remember in this case to remove connections with the manifold.
- Mark these Heating/Cooling Zones where no loops are to be arranged and change their type to Without pipes.
Calculations and diagnostics
Radiant system calculations
- Launch complete calculations by clicking the
icon in the Calculations section of the toolbar.
- Open the Diagnostics window by selecting it in the list of windows or by pressing F8.
- After calculations are completed verify the messages listed in the Diagnostics window. If error messages are displayed, these must be eliminated in the first place.
For more information, see: Calculations and diagnostics
Modifying system parameters to adapt attained output to required output
- Change feed temperature of the radiant system by using control circuits, which can be found in General data window in Thermal systems/Sources section.
- Change pipe spacing and temperature drop in individual loops.
- Change structure of heating floor\wall.
- Change Max. press. drop in circuit.
Modifying the dividing line of element Heating/Cooling Zone to elements Heating-cooling surface
For more information, see: Modifying the dividing line after automatic division
Manual correction of automatically generated pipe feeds route
For more information, see: Pipe feeds route - manual correction of automatically generated pipe feeds route
Appending drawings with radiant system loops
For more information, see: Appending drawings with radiant system loops
Including of drawing loop lenght in the calculations
For more information, see: How to include the drawing loop lenght in the calculations?
Using of plates in dry floor heating system
For more information, see: Inserting plates in dry floor heating system
Recalculation and verification of results
- Verify calculation results paying special attention to:
- coverage of heat demand in rooms,
- sized layers in Heating/cooling floor, to see if there are no undesirable differences in height/thickness in adjacent areas.
- bills of materials.
- coverage of heat demand in rooms,
Prepare drawing for printing/export
Label
