If the room-by-room heating load is included in the calculation, static balancing offers the best cost-benefit ratio among balancing solutions for detached and semi-detached houses or multi-family houses with small residential units. This is because the pressure-dependent thermostatic or balancing valves required for its implementation are already present in most existing systems or can be retrofitted at low cost if necessary. Even with underfloor heating systems, static balancing is completely sufficient for smaller residential units, as dynamic balancing only offers insignificant advantages due to the inertia of the system. Static pre-balancing in combination with adaptive heating optimization based on room temperature achieves the best results here.
