Mixing is a key element in many hydronic heating systems. When properly performed it:
- improves comfort and minimizes energy consumption
- protects low-temperature heat emitters from high-temperature heat sources such as storage tanks heated by solar collectors or wood-fired boiler systems
- prevents sustained production of corrosive flue gas condensation when a conventional boiler is used as a heat source to a low-temperature distribution system
Over the past 20 years, mixing products have advanced into more intelligent and durable devices. A solid understanding of how they function and how to apply them will enable maximum heating system performance. This issue of idronics discusses a wide range of mixing options for use in both standard and specialized applications.
