Abstract

•The article presents a method for feedforward control of supply temperatures in hydronic heating systems based on outdoor temperatures and local feedback at room level using thermostatic valves enhanced by using a central feedback control of the supply temperature based on average indoor temperature.•The enhanced control method is evaluated primarily with respect to the resulting indoor temperatures compared to those created by the original control system.•The indoor temperatures became less dependent on the outdoor temperatures, indicating improved control of the hydronic heating system.•Correct commissioning and understanding of the limitations of the enhanced control are important factors for successful results.
