Energetic Comparison of Different Instantaneous Water Heater Concepts in a Solar Combi-System for a Multi-Family House with TRNSYS
Abstract
Instantaneous water heaters in multi-family houses improve the efficiency of solar thermal systems. Therefore, four different concepts of instantaneous water heaters are simulated with TRNSYS. The paper discusses the most important parameters of the instantaneous water heater and the impact of the storage set temperature.
