General description of the software

The “Audytor H2O, version 1.5” software provides a graphical support for designing of cold, hot and circulating water systems in traditional layouts, as well as in serial, manifold and tee layouts in residential and public buildings. The software also enables the user to select thermostatic valves for circulating water systems.


  • Capability of designing a few systems in one design,
  • Unlimited system size (even thousands of sanitary appliances and draw-off points),
  • Efficient and very fast calculation process,
  • Design error analysis,
  • Building backgrounds (blueprints) in the most popular vector and raster formats.

The application’s catalogue database includes information on the pipes, plumbing fixtures, recipients, sanitary appliances and heat sources manufactured by the leading domestic and foreign companies. The application’s high flexibility enables the user to employ, at the same time and in one design, plumbing fixtures, pipes and sanitary appliances from various companies.
The “Audytor H2O” software allows designs of very large water supply systems.

The application enables the user to make full hydraulic calculations of water supply systems. As part of such calculations the software:

  • Calculates nominal water flows in pipes.
  • Selects pipe diameters.
  • Determines the hydraulic resistance of individual system components.
  • Determines the required available pressure.
  • Controls water flows in the circulating piping of domestic hot water systems by selecting appropriate control devices (preset valves, orifices, thermostatic valves).

As part of thermal calculations, the application has the following functionalities:

  • Calculates the required water flow in the circulation piping of domestic hot water systems by using a thermal method determining hot water cooling in individual sections.
  • Selects thermal insulation for pipes.
  • Selects temperature setpoints for thermostatic valves while taking into account water cooling in the circulation piping.

Working with the application

Our software operates in the MS Windows™ environment which makes it user-friendly, while standard rules for working with applications specific to this environment, significantly facilitate software operation to persons familiar with the Windows system. 

Many solutions are employed in the software to make work easier and efficient. The most important of them include:

  • Graphical process of data input and result presentation on a developed view (see Figure. 1).
  • Enhanced context-sensitive help system recalling information on the software’s individual commands as well as hints on the data being inputted
  • Windows environment allowing the user to view, at the same time, many types of data, results, etc.
  • Simple co-operation with printer and plotter, print preview and plotting functions
  • Extensive error diagnostics and automatic troubleshooting functions (both in tables and on developed views)
  • Fast access to the catalogue data on pipes, recipients, sanitary appliances and plumbing fixtures.

Data input


Figure 1. Data inputted in a graphical form on a developed view

Data is inputted in a graphical form on the developed view (see Figure 1). Necessary information on the components being drawn is entered in tables linked to the developed view. This enables the user to edit single pipes, recipients, sanitary appliances, plumbing fixtures and whole marked groups.
Each inputted component is connected with a system checking its correctness and a help system providing the user with information on the quantity being inputted or with the relevant catalogue data.

In order to streamline the data input, the software is fitted with:

  • Capability of editing many system components at the same time,
  • Capability of using ready blocks,
  • Intelligent functions duplicating any parts of a drawing horizontally (housing systems) and vertically (traditional vertical systems) including the renumbering of rooms and sections,
  • Capability of defining an unlimited number of the user’s own blocks consisting of any parts of a drawing,
  • Fast access to auxiliary information on the quantities being inputted,
  • System of pop-up buttons streamlining access to the most frequently used water system components,
  • Function dynamically linking data from a drawing with data in the corresponding table,
  • System supporting the connection of pipes, plumbing fixtures, recipients and other water system components.



Figure 2. Example of duplicating data on further levels

Editing the data in a tabular form enables individual setting of parameters of many drawing components that are marked simultaneously. The dynamic linkage between the drawing and data table makes the edited component highlighted on the developed view.

Delivered with the software, a library of standard drawing parts (blocks) such as riser-storeys, elements of apartment and manifold layouts allows the user to quickly create the developed view. Additionally, the user can define practically unlimited number of his/her own blocks including any parts of the drawing. Such blocks can be used in successive designs.

With the function duplicating any parts of the drawing it is possible e.g. to introduce a part of the system’s developed view for the whole storey (successive risers or apartment layouts) and then automatically generate the developed views and data for the next storeys (see Figure 2).

Graphics and editing


Figure 3 Graphical editor

The application is equipped with a fully functional graphical editor, based on a system of drawing layers, enabling the user to draw any objects, including curves and open polygons. The graphical editor also enables the user to define the parameters of drawing layers such as line name, colour and style, filling colour, visibility, printing, font parameters, etc. It is also possible to set individual features of the graphical objects being drawn. The graphical objects drawn up can be scaled, rotated and moved on screen. The graphical editor employs crosshair cursor, horizontal and vertical rules, orthogonal drawing, screen grid and cursor jump setting, in order to facilitate drawing graphical objects.

Building backgrounds

Building backgrounds can be loaded into the software from graphical raster or vector files or scanned directly into the software in case of hard copy documentation. The application supports AutoCAD's vector files in DWG and DXF formats and raster files in TIF, JPG, BMP, WMF, EMF, GIF, and PNG formats. The software supports scanners compatible with TWAIN technology.

The module supporting raster files enables the user to load hard copy technical documentation as a building background directly into the software via a scanner. This module provides active help with selecting the resolution and quality of scanning and with recording the scanned documentation in the selected graphical format.

Figure 5. Scanning the building background

Once a building background has been scanned or loaded from a raster file it can be adjusted (see Figure 6) to improve its legibility. A module supporting raster graphics enables the user to adjust brightness, contrast and amplification, as well as to use filters smoothing the drawings and a threshold when converting into black and white raster, remove “trash” from the drawing after scanning, etc. Simultaneous observation of the original, the individual adjustment phases and the adjusted version in a sample form enables the user to observe individual step-by-step adjustments and select the optimum option for improving legibility of the loaded building background.

Once loaded and adjusted, the building background can be subjected to dimensional treatment (see Figure 6) consisting in scaling, clipping, levelling and rotating. This stage is particularly important as it enables the user to utilise the loaded building background when inputting graphical data into the software. The correct scaling and levelling of the building background allows the lengths of individual system pipes to be loaded correctly. The application provides convenient scaling and levelling tools for the loaded building backgrounds (see Figure 7).

Drawing floor plans


Figure 8. Floor plan with added recipients and sanitary appliances. [Enlarge drawing]

An interesting function of the “Audytor H2O“ software is the possibility of marking calculation results on floor plans (Figure 8). To this end, a floor plan should be drawn and then recipients, sanitary appliances, pipes and other system components marked thereon. Once the calculations have been completed, the application will provide pipe diameters and valve settings.

If a designer has floor plan backgrounds drawn by applications creating DWG, DXF, TIF, JPG, BMP, WMF, EMF, GIF, PNG (AutoCAD, CorelDRAW, MS Word etc.) files, they can be loaded into the “Audytor H2O” software.  This allows close cooperation between the architect and the designer of water supply systems and contributes to a significant shortening of the design process.

Using the function loading WMF files into the software, any drawings, texts and tables, created by other applications working in the MS Windows environment, can be placed in both developed views and floor plans.

Checking data and calculation results

When inputting data, a data validity check is made by the software on an ongoing basis. This significantly reduces the number of errors. A full data check for correctness is made during the calculation process.

As a result of the data and result checks, a list of identified errors is generated. The list contains information on each type of error and its location. Extensive error diagnostics enables the designer to fully assess the design quality.

The application is equipped with a mechanism for a quick search of the error location (the table, line and column with erroneous data is automatically found and the faulty component is indicated on the developed view).

Calculation results


Figure 9. Preview of calculation results to be plotted

The calculation results are presented in both tabular and graphical forms. The format of individual system component labels can be freely modified (the selection of displayed values, colours, font sizes, etc.).

Also, the contents of all tables can be formatted (the selection of displayed columns, lines, font sizes, etc.) and sorted according to any key.

Calculation results can be plotted or printed. The user can choose a scale for the drawing and use the drawing preview to see how the developed view will be drawn on paper. If the drawing does not fit on a single sheet, the application draws the developed view in successive parts, which can be glued together into one picture. Thus, using even the simplest A4 printer, large drawings can be obtained.
The application is also capable of saving drawings in DXF and DWG formats. The saved drawings can be later loaded into, e.g. the Auto CAD application. A drawing in a DXF or DWG format is divided into layers and the typical components of the system are recorded in a form of blocks.

The tables with calculation results can be either printed or exported to other applications working in the Windows environment (e.g. worksheet, text editor, etc.). The printout preview capability enables the user to view the pages before they are printed on paper.

Catalogues of the software are supplemented gradually. Companies and individual users of the software are requested to send us the catalogue data on devices which you would like to find in the successive upgraded versions of the software.
