pewo - Model Therm IDD -Consumer Unit
Consumer substation with integrated indirect space heating circuit, suitable for local micro heating networks. pewoTherm IDD is a heating substation with an indirect heating circuit and domestic hot water preparation by the hygienic continuous flow principle and using a plate heat exchanger. The TFS controller keeps the water temperature constant. The high thermal length of the plate heat exchanger guarantees high tap output at low return temperatures. A plate heat exchanger separates the heating circuit from the heating system. The heating circuit is supplied by an integrated circulating pump. An optional expansion vessel for the heating circuit can be added on the left-hand side of the system. The flow temperature of the heating circuit can be controlled by a thermostatic TFS controller (fixed value) or by an electronic controller controlled by atmospheric conditions.
