Scope of lesson

The article shows how to make a fast appraisal and how to draw up a list of radiant heating system components by means of the InstalSystem SMART mobile application.

Modules and program configuration

Steps to perform

Preparing the working environment

  1. Download the application.
    InstalSystem Smart can be obtained upon contacting InstalSoft s.c. at: info@instalsoft.com.pl.
    The test version can be obtained through:
    • a link to the installation file in case of Android devices. The file should then be moved to the internal memory of the device and installed at the operating system interface level,
    • an e-mail with an invitation to closed TestFlight tests in case of iOS devices. The invitation is sent to the e-mail address linked to the obligatory user's account on AppStore which enables installation of the application at the AppStore interface.
  2. Install the application on the mobile device.
  3. Launch the application.
  4. Enter the user's data:
    • First name
    • Surname
    • E-mail address to which project files will be sent
    • Company
    • Address (Street)
    • Zip (postal) code
    • City
    • Telephone.
      1. Settings

Start page

  1. Open new project.
  2. Open existing project.
    2. Start page

Specifying project default data

  1. Enter project data:
    • Project name
    • Customer's e-mail and additional e-mails, if any.
      3. Project data

  2. Enter building data:
    • Building location
    • Heat loss coefficient.
      4. Building data

  3. Enter heating system data:
    • Fastening system
    • Pipe type and diameter
    • Manifold type
    • Manifold Set type
    • Manifold cabinet
    • Control system
    • Default room thermostat
    • Max. working load
    • Supply temperature - determined automatically or specified by user
    • Default pipe spacing
    • Screed type
    • Covering.
      5. Heating system data

Project editing - managing storeys

  1. Add the required storeys.
  2. Enter storey data.
  3. Enter building surroundings data.
    6. Managing storeys

Project editing - loading underlays (base drawings)

  • The underlays may be in the form, for instance, of graphics loaded from a gallery, or a photo from a camera.

Project editing - entering and editing room data


Project editing - entering and editing manifold data


Project editing - entering rooms to manifolds


Calculations and diagnostics

  1. Launch calculations.
  2. Verify diagnostic messages.
  3. Verify calculation results, in particular:
    • heat demand coverage in rooms,
    • bills of materials.
  4. Sending project to e-mail address.

Additional information

Continuation of the design in the InstalSystem 5

Result of calculation in the InstalSystem Smart 5 can be continued in the InstalSystem 5.

Other functions

  1. Change viewing scale of drawing:
    7.Change viewing scale of drawing.

  2. Edit component data (invoke the function and select the component):
    8.Edit component data.

  3. Change the size of the room label\heating surface area and the distributor icon:
    9.Change the label size.

  4. Load plan of storey (from gallery or take a photo and use it as an underlay):
    10.Load plan of storey.

  5. Remove component (invoke the function and select the component):
    11.Remove component.

Data exchange via internet

  • STEP: Launch application and complete user profile.
    No data is exchanged with the server and internet connection is not used.
  • STEP: New project execution.
    Data exchange is low and the type and speed of the connection is not meaningful.
  • STEP: Project editing (general).
    No data is exchanged with the server and internet connection is not used.
  • STEP: Calculations.
    Data exchange is high.
  • STEP: Sending project data to an e-mail.
    Data exchange is high.
