Hydraulic balancing – for efficient operation

According to an exemplary study for Germany (see dena-Gebäudereport), buildings use up about 35 % of general energy consumption, and of that about 75 % are consumed by HVAC systems. Consequentially, hydraulic balancing is not only indispensable for reliable and especially for cost- and energy-efficient operation, it is actually a requirement stipulated in a number of standards and guidelines (DIN 18380 / VOB 3.1.1, GEG / DIN V 4701-10, DIN EN 14336). 

Why is hydraulic balancing so important?

The aim is to provide the right amount of water at the right place, at the right time. In other words, heating and cooling water is to be distributed to all consumer installations in line with the demand. To achieve this, all parts of the hydraulic system have to be matched and balanced.

Minor action, major effect: In accordance with the Optimus study conducted in Germany, hydraulic balancing can potentially save up to 21 %. Given its comparatively low investment costs, it has got an excellent cost/benefit ratio.

Heat distribution before and after hydraulic balancing

Hydraulic balancing achieves optimum heat distribution.

Win-win situation for all involved: consultants, engineering contractors, operators and consumers

Energy-efficient operation of an HVAC system

  • Less water required to circulate, enabling the use of a smaller heating pump
  • ­Lower energy input due to lower supply temperatures
  • ­Optimum use of renewable energies due to optimum return temperatures

Operating reliability

  • ­Hydraulically balanced systems reduce maintenance and technical complaints.

Maximum living comfort

  • ­Even heat distribution over the entire building (HVAC system)
  • ­Low noise emissions due to defined pressure conditions and low flow velocities

Balancing valves: The reliable caretakers.

As water always seeks the path of least resistance, resistance is created by additional system components to create an even, demand-driven distribution. This function of hydraulic balancing is taken care of by balancing valves.

BOA-Control / BOA-Control IMS

Shut-off, balancing and measurement function in a single valve

Universal use as a static balancing, measurement and shut-off valve with innovative ultrasound technology

  • Cost-efficient hydraulic balancing, especially for constant-flow systems
  • Straightforward, error-free flow measurement (no need to enter the valve position)
  • Innovative ultrasonic flow measurement (Q, T) prevents leakage as no sensors are in contact with the fluid handled.
  • Cost-efficient permanent measurement with BOATRONIC MS-420

BOA-Control DPR

Creating pressure-independent zones the easy way

Differential pressure regulator with continuous setpoint adjustment for maximum flexibility

  • Easy commissioning and initial balancing with system sections that are independent of each other in terms of pressure (zoning)
  • Optimised energy consumption by constant control quality of downstream thermostatic and/or partner valves (e.g. BOA-Control SBV)
  • Optimal supply of consumer installations in part and full load operation (dynamic balancing)
  • Defined pressure conditions prevent flow noise.
