Heat Pump Cascades – Design, Optimisation and Practical Examples
22. October 2025, 16:00 - 16:45 CEST
Heat pump cascades are becoming increasingly common in practice. In this practice-oriented Polysun webinar you will learn which advantages they offer over individual systems, and how heat pump cascades can be precisely designed and simulated.
In the webinar, we will cover:
- Introduction to heat pump cascades: what is a cascade and how does it differ from individual systems?
- Presentation of the new Polysun templates, focusing on the following configurations: parallel cascade, serial cascade, hybrid systems
- Typical areas of application: apartment buildings, schools, hotels, commercial and industrial facilities
- Design tips: selecting the right heat pump(s), hydronic system integration, controllers, buffer storage dimensioning
- Simulation as a crucial planning tool – dynamic, with precise simulation time-steps, economically efficient
Why should you participate?
- Get to know the new templates.
- Specific use cases show you which cascading is worthwhile – e.g. for highly fluctuating heat loads or multiple temperature levels.
- Planning reliability through simulation: you will learn how to optimise your system design using simulation software (e.g. Polysun) – for efficiency, service life and CO₂ reduction.
- Increased efficiency and cost-effectiveness: when properly designed, heat pump cascades can significantly reduce energy and operating costs.
- Questions and answers
Target groups: system design engineers, energy service providers and energy consultants
Duration: 30-minute presentation + 15 minutes of questions and answers
Participation in the webinar is free of charge.
