The three keys to perfect hydronic control

To obtain the desired indoor climate at the lowest possible energy cost three conditions must be fulfilled.

Condition 1 – The design flow must be available at all terminalsIn order to achieve this first condition, hydronic balancing is necessary.
Hydronic balancing prevents overflows in certain circuits from causing underflows in others. Hydronic balancing detects possible over-sizing of pumps and verifies that the plant actually provides the functions and performance intended by the designer. Read the article - open as pdf

Condition 2 – The differential pressure across control valves must not vary too muchAgain, hydronic balancing is necessary for this condition to be fulfilled. In fact, hydronic balancing is the only way to identify and resolve the real causes of operational problems in the plant. Read the article - open as pdf

Condition 3 – Flows must be compatible at system interfacesIn order to fulfil this condition, hydronic balancing is also necessary, so that the installed power in the plant can be delivered. The balancing procedure allows you to localise and resolve any hydronic problems. Read the article - open as pdf

The best way to attain these three conditions is to perform a balancing procedure in order to ensure that the plant actually performs according to design.
