Hydronic Balancing is the process of optimizing the distribution of water in a building’s heating or cooling system so it provides the intended indoor climate at optimum energy efficiency and minimal operating cost.
To provide the correct power output heating or cooling devices require a certain flow known as the design flow. Theoretically it is possible to design plants that deliver the design flow at each terminal unit (heating or cooling device). In reality this is not possible because pipes and valves only come in certain sizes and accurately predicting the real flow in a system is too complex. Some circuits (typically those closest to the pump) will be favoured by higher than required flows at the expense of other circuits that will have underflows.
A properly balanced hydronic system
Optimize efficiency by supplying sufficient heating or cooling to all parts of the building. Maintains comfortable, stable temperatures throughout a building. Reduces energy costs by operating pumps at lowest possible loads which saves energy, reduces the need for maintenance and extends equipment life.
