Solution Overview
Problem
Conventional static hydronic balancing in heating systems leads to uneven heating of rooms, reduced valve authority, increased energy consumption, and potential for dirt deposits and blockages due to preset valve settings, which limits radiator performance and increases heating times.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If static hydraulic balancing is performed with preset valve settings, then the heating system can be configured for specific design conditions, but the valve authority is reduced and radiator performance is limited
Solution Approach 1:
The patent implements dynamic hydraulic balancing where valve positions are continuously adjusted based on real-time temperature measurements and heating requirements. Instead of static preset settings, the system dynamically optimizes valve openings to maintain equal temperature increases across all rooms, thereby preserving full valve authority while adapting to changing conditions.
Solution Approach 2:
The system changes the operating parameters of valves from fixed preset positions to dynamically variable positions. By continuously measuring temperature differences and calculating optimal valve openings, the system adjusts valve parameters in real-time to maximize radiator performance while maintaining hydraulic balance.
2Ease of operation
If preset valve settings are used to balance hydraulic flow, then flow distribution can be controlled, but dirt deposits and blockages occur more frequently
Solution Approach 1:
The patent employs dynamic valve adjustment that adapts to actual system conditions rather than relying on fixed preset settings. By continuously monitoring temperature differences and adjusting valve positions accordingly, the system maintains optimal flow distribution without the need for aggressive preset restrictions that promote dirt accumulation and blockages.
Solution Approach 2:
The system performs self-adjusting hydraulic balance by automatically detecting temperature differences across rooms and modifying valve positions in response. This self-regulating mechanism eliminates the need for manual preset configurations that create restrictive flow conditions prone to contamination and blockage.
3Power
If radiators are oversupplied with heat transfer medium, then heating capacity is increased, but energy consumption rises unnecessarily
Solution Approach 1:
The patent implements a feedback control system that continuously monitors temperature differences between rooms and adjusts valve positions to eliminate oversupply. By measuring actual heating performance and dynamically modifying flow distribution, the system ensures each radiator receives only the heat transfer medium necessary to achieve the target temperature increase, thereby eliminating wasteful energy consumption while maintaining adequate heating capacity.
Solution Approach 2:
The system dynamically changes flow parameters to match actual heating demands. By adjusting valve openings based on real-time temperature measurements, the system optimizes the volume flow through each radiator to provide exactly the heating capacity needed, preventing both oversupply waste and undersupply shortfalls.
4Adaptability or versatility
If different rooms heat up at different rates due to hydraulic imbalance, then individual room characteristics are accommodated, but uniform heating is not achieved
Solution Approach 1:
The patent employs feedback control where temperature sensors in each room continuously monitor heating progress and the central control unit adjusts valve positions to equalize temperature increases across all rooms. This feedback mechanism dynamically compensates for individual room characteristics such as thermal mass, insulation quality, and heat loss rates, achieving uniform heating while accommodating room-specific requirements.
Solution Approach 2:
The system applies local adjustments to each radiator valve based on the specific heating requirements of individual rooms. By measuring temperature differences locally in each room and adjusting the corresponding valve position, the system provides customized flow distribution that achieves uniform overall heating while respecting individual room characteristics.

AI summary
The present invention relates to a method for operating a heating installation (1) in a building having at least two spaces (R1, R2). The heating installation (1) comprises at least one heating body (HK1, HK2) for each space (R1, R2), a heat generator (WE) for heating a carrier medium that flows via an outbound line (VL) to the heating bodies (HK1, HK2) and via a return line (RL) back to the heat generator (WE), a pump (P), arranged in the outbound line (VL) or in the return line (RL), for delivering the carrier medium, and a central control device (Z) for controlling the heat generator (WE) and the pump (P). The heating bodies (HK1, HK2) each comprise a regulating member (V1, V2) for setting a volumetric flow through the heating body (HK1, HK2) and a setting device (E1, E2) having a temperature sensor for determining an actual temperature (TR) of the space, a controller for setting a degree of opening of the regulating member (V1, V2) in dependence on a respectively indicated setpoint temperature (TR,W) for the space and on the determined actual temperature (TR) of the space, and a communication device for communicating with the central control device (Z). The method involves the steps of: in the event that in one space (R1, R2) an actual temperature (TR) of the space is below an indicated setpoint temperature (TR,W) for the space, and the difference between the actual temperature (TR) of the space and the indicated setpoint temperature (TR,W) for the space is greater than an indicated temperature difference (∆T), the heating bodies (HK1, HK2) of the space (R1, R2) operate in heating operation; in the event that heating bodies (HK1, HK2) are operated in heating operation in more than one space (R1, R2), determining a heating value (ṪR) in dependence on a change in the temperature of the space (dTR) within a predetermined time period (dt) for each space (R1, R2) with heating bodies (HK1, HK2) in heating operation; for each heating body (HK1, HK2) in heating operation: indicating an upper limit value (Hmax) for the regulating member opening in dependence on the heating value (ṪR), determined in each case, and an average value ((ṪR)) of all determined heating values (ṪR) and operation of the heating bodies (HK1, HK2) in dependence on the indicated upper limit value (Hmax).
