Hydronic Flow Optimization turns your design goals into reality.

Discover total system performance solutions to optimize delta-T through precise control. Make your building operations more efficient and bring balance to your bottom line. 

Achieve your design intent with hydronic flow optimization​​

The right devices in a hydronic system can lead to greater energy efficiency and significant savings in first costs and lifecycle costs. ​


Hydronic flow optimization is a prime way to reduce HVAC energy consumption up to 30%, while increasing overall building efficiency, operational performance and overall comfort. Commercial buildings consume about 40% of all energy worldwide*, and HVAC systems account for more than 40% of buildings’ energy usage.​​


Siemens provides the right valves, variable frequency drives and differential pressure sensors for optimal hydronic system balancing.


Pressure Independent Control Valves (PICV) ensure balanced water flow rates under all load conditions, thereby eliminating any impact of fluctuations on the room temperature.  This maximizes delta-T and increases overall efficiency in your system.  Optimizing precise flow control leads to the right balance in your system with no sacrifice on comfort  combined with Variable Frequency Drives (VFD) and Differential Pressure Sensors, you can reduce energy consumption even more.

An easier delta-T solution

Siemens PICVs have the unique advantage of always maintaining their full stroke, regardless of the maximum adjustable flow setting, to provide better control. This significantly reduces or eliminates hunting for the right actuator setting, resulting in better control and increased comfort.

Siemens pressure independent control valves reduce Peachtree Center’s energy usage by 13.8%

Commercial office buildings require a vast amount of energy and water to heat and cool the indoor environment. Peachtree Center was no exception, and the hot, humid Atlanta summers made the challenge even more daunting. Siemens presented Peachtree Center with an innovative and cost-effective solution using pressure independent control valves.
