Abstract (en)

[origin: EP4242528A1] The invention relates to an arrangement for heat exchangers of a district-heating system of a building, wherein the arrangement includes• a domestic-water heat exchanger (10),• a domestic water circuit (15),• a separate circuit-water heat exchanger (20),• a control valve (22) of the circuit-water heat exchanger (20) for controlling the flow rate of the district-heating water conducted to the circuit-water heat exchanger (20).According to the invention• the circuit-water heat exchanger (20) is configured to heat the domestic water to a setpoint temperature 1 - 5 °C, advantageously 2 - 4 °C, higher than the domestic-water heat exchanger (10), and• the design inlet temperature of district-heating water for the circuit-water heat exchanger (20) is 2 - 10 °C, advantageously 4 - 6 °C, lower than the design inlet temperature of district-heating water for the domestic-water heat exchanger (10).The invention also relates to a corresponding method.
