Wall-mounted instantaneous DHW heater
FW module are designed for instantaneous DHW production. Installation with a thermal storage is ideal solution in small to medium-sized applications. FW modules can be installed individually or in cascade up to 8 modules. They ensure from 2 to 320 L/min DHW capacity.
FW modules are ideal in reduced room for installation conditions. They drastically reduce maintenance expenses, and improve home safety by reducing hazard from Legionella in DHW systems.
FW modules facilitate energy efficient installations by storing heated water at higher temperature than DHW.
FW40 / FW40 PLUS: The temperature regulation is set out through a control unit combined with a flow sensor.
The product is factory set for installations in cascade systems.

MIXER VALVE KIT FW40
Thermostatic mixing valve kit allows upstream temperature regulation in FW instantaneous water heaters. The system improves in accuracy for comfort in primary high temperature conditions.
Packaging composed of:
- Mixer Valve.
STORAGE STRATIFICATION VALVE KIT FW40
The storage stratification kit allows directing the return flow from the producer to the lower part or mid-section of the accumulator. By comparing various temperatures, it promotes the stratification phenomenon inside the thermal accumulator, maximizing the efficiency of the entire heating system.
Packaging composed of:
- Mixer Valve;
- Temperature sensor S5;
- Temperature sensor S6.
