  • Error-free system planning even for less experienced installers

  • Available free of charge for Vaillant trade partners in FachpartnerNET

  • Intuitive operation and immediate use

The new heat pump quick design tool from Vaillant enables simple, fast and reliable planning of a heat pump or hybrid system. By entering just a few quickly available data, the safe and technically correct configuration of a heat pump system is possible. The software checks the entered data for plausibility and possible inefficiencies in the system design. In this way, errors in planning are avoided. In addition, the software provides the installer with all setting values, including the bivalence points or the maximum residual head of the pump for the designed system. Even installers who have little experience in system planning can use the heat pump quick design tool to design and install technically flawless and error-free systems. The new software can be used free of charge by all Vaillant installers within the FachpartnerNET.

Reliable system planning even for beginners

"Our goal is to enable even less experienced installers to design a heat pump system reliably and without errors," describes Gerrit Lau, Head of System Consulting at Vaillant Germany. For the project, we determined and evaluated the most common errors in the planning and installation of heat pump systems. Together with installers, we then simplified and standardized the planning and design of a heat pump system. The software guides users through the system planning process in a series of self-explanatory steps and queries the relevant data. For example, the tool starts with the entry of the property's zip code in order to calculate the standard outdoor temperature in the background. Two different options are available for the actual heating load of the building - either by specifying the living space and simple data on the type of building or by entering the gas or oil consumption of the last three years. If the user selects a supply temperature of more than 55 °C, the "bivalent alternative" operating mode is automatically selected. This procedure avoids possible inefficiencies already during the design of the system.

In all design steps, users can call up further information on request, offering explanations of the effects of a decision in the composition of the heat pump system. In addition, current electricity and gas prices can be stored. Finally, both the object-specific heat pump system with its elements and an initial consumption forecast can be viewed. The entire planning data is used to generate a PDF file for the design, installation instructions and settings of the heat pump system. The installation instructions contain particularly practical information such as the size of the system components and the position of the connections. The software itself is simple and intuitive to use. "Installers can start designing a heat pump directly without a time-consuming introduction to the software," says Lau.
