Hydronic balancing

In hydraulic heating and cooling systems, the energy carrier is transported over piping sections of different lengths. On the path from the energy generator to the consumer, pipe lengths and turns, branches, valves and heat exchangers present their own resistance that inhibits flow through their cross-sections and surface roughness. Energy in buildings must be distributed in such a way that all building sections, rooms and consumers are optimally supplied according to their needs. A balanced system avoids excess and wasteful supply of consumer circuits and prevents irritating flow noises in the pipes and valves. The gain in comfort due to pleasant room temperatures and significantly increased energy efficiency are the per­ceptible and measurable results of hydronically balanced flow systems.
