The mini DHW module piccolo is used as a DHW station for multi-storey buildings and in single-family houses.

Decentralised DHW heating:
The domestic water is heated in the flow principle only during the request via a stainless steel plate heat exchanger. In heating systems with a buffer, the heating water is pumped through the heat exchanger with the help of a central regulated circulation pump, depending on the pressure loss during the tapping process.

Control function:
The central control element is the proportional flow controller PM without external energy. It regulates the heating water flow that is required for DHW heating. The DHW temperature can be set with the setting lever on the proportional flow controller. The temperature provision valve prevents stagnation in supply lines.
