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.
FW20: The temperature adjustment is set out through a thermostatic valve and a flow sensor driven 3-way valve.
