WP-OPT© - a software to design and simulate heat pump heating systems and calculate Energy Label
The simulation software WP-OPT© helps you to design heat pump heating systems. Additionally you can compare different heating system configurations concerning the operating results.
Suggestions about the operating behaviour and the efficiency of the heat pump heating system are very difficult to make without a computer-based simulation. That is because the technical parameters of heat pump, heat source and heat delivery influence each other. Our software uses an iterative approach to calculate the temperature curve of the heat source caused by the heat withdrawal. Depending on the technical parameters of the heat pump, the current heating water temperature and the heat source temperature, the running time and the power consumption of the heat pump are calculated. They are the basis for calculating the coefficient of performance (COP) and for providing a comparison of operational costs to conventional heating systems.
Water-water, air-water and brine-water systems (the latter also with direct evaporation) are possible as well as systems with bivalent and monoenergetic mode of operation.
Naturally our software assists you in designing a heat pump heating system. Warnings appear when input or result data are out of given ranges.
The software WP-OPT© comes with a database of 1100+ heat pumps, climatic data of Germany, Austria and Switzerland and material data of 60 kinds of ground. Moreover you can extend the database with your own data. Climatic data of other european countries are available.
Additional modules extend the functionality of the program. For example the 'Solar module' allows the consideration of the usage of a solar thermal system for hot water service, heating support and increasing the heat source temperature.
You can also display and print several reports showing all the input and result data. It is no problem to create reports for your special use on your own.
You can download an english demo version for free from our download page.
We also offer online tools for the design of heat pumps and the label calculation regarding the new Ecodesign Directive and the new Energy Label ErP (Energy related Products).
The calculation is based on DIN EN 14825.

Please don't forget to note which additional modules you want.
The standard version is shipped with climate data of Germany, Austria and Switzerland. If you need climate data of other countries, please let us know. We'll send you an offer for these.
If you are a manufacturer of heat pumps, you can download the program WPOedit© to edit the database of our software WP-OPT©.
The manual contains an installation guide and an explanation of how to edit the heat pump data in the database.
