Do it right: Dynamic hydronic balancing

Dynamic hydronic balancing

We have a responsibility to create buildings that are better for people and that are sustainable for the environment – and that means transforming buildings into environments that care.

Buildings consume about 40 percent of all energy worldwide, and HVAC systems account for more than 40 percent of buildings’ energy usage. That’s why optimizing HVAC systems is essential for the future. But people don’t want to compromise on comfort – so we need to build energy-efficient HVAC systems that adapt to peoples’ needs and keep comfort at the highest level. Hydronic flow optimization is a prime way to reduce HVAC energy consumption while also increasing overall building efficiency and operational performance.

Learn how to create energy-efficient HVAC systems with optimized hydronic flow that deliver the highest level of comfort: dynamically balanced hydronic systems.

Why balance a hydronic system?

Water always flows through the path of least resistance.

However, the HVAC system’s pipe network in buildings is highly branched and contains pipes of different diameters. This means that the water and therefore the heat are distributed unevenly, and some consumers get more heat than others. The consumers farthest from the pump are supplied with too little heat, and those nearest the pump get too much. As soon as one room occupant turns on the heat, another area of the building will inevitably get less heat. This leads to unstable room temperatures, and the comfort of the occupants is impaired. Energy is wasted and unnecessary costs are triggered by excessive and unnecessary heating/cooling.


Hydronic balancing can prevent this situation from occurring. The simplest definition of hydronic balancing is:

The right amount of water at the right time in the right place.

Sounds easy! But is it?

It means that the water is distributed in the optimal way. With hydronic balancing, all components in the hydronic system are matched and balanced, ensuring that energy is distributed evenly throughout the system. There are several ways to create a balanced hydronic system.

In other words: Dynamic balancing is the right way to do hydronic balancing.
