ISX 13: Hidden in the wall!
Integrated, robust and smartly networked

Product innovation
The new ISX 13 e-module instantaneous water heater has been specially developed for flush-mounted / pre-wall installation. Its concept is ideal for flexible integration into the building infrastructure: it enables simple installation without wall brackets and without removing the hood.

Awards E-module instantaneous water heater ISX 13

Fully electronically controlled modular instantaneous water heater with sensor keypad and LED display for convenient and economical hot water supply to one or more draw-off points
Temperature setting, definition of individual temperature profiles and viewing of consumption values via the supplied e-paper remote control FX Next or optionally via smartphone
Always temperature accurate to the degree between 20 °C and 60 °C thanks to TWIN TEMPERATURE Control TTC® and dynamic flow rate control SERVOTRONIC®
Bare wire heating system IES® ensures a longer service life, less scaling and is efficient and easy to maintain
Electronic safety system with air bubble detection, temperature and pressure shut-off, and water stop function
Multiple Power System MPS® determines the maximum power consumption at installation: 11 or 13.5 kW
Exceptionally low switch-on water flow from 1,5 l/min thanks to innovative water flow technology
IntegratedWLAN and Bluetooth® function for connection with smartphone and tablet (the free "Smart Control" app is required for this)
Modbus interface for integration into building services
Suitable for reheating preheated water (supply temperature up to 70 °C permissible)
Directinstallation option as part of a pre-wall installation (if required in the optionally available CLAGE flush-mounted cabinet with inspection flap), in drywall or above a suspended ceiling (without separate wall bracket)
Assembly and electrical connection possible without removing the hood
Free access water connection from below with ½ inch external thread and shut-off valve
Dimensions (height × width × depth): 40.2 × 27.8 × 9.9 cm
