ATON - Power to Heat

Icon Energy management, Power-to-Heat

ATON is a plug & play solution for using surplus PV energy – without additional wiring. It consists of an energy meter and an immersion heater, which can be variably controlled from 50 W to 3 kW, for installation in a buffer cylinder. Through a wireless connection, the energy meter (x2-tech) specifies the output the immersion heater can consume. The immersion heater sends all measurements (high limit safety cut-out, internal temperature and the values of the two external sensors) back to the energy meter.


  • Minimal installation effort thanks to new x2 wireless technology and factory program
  • Freely programmable for individual requirements
  • Energy meter and immersion heater are connected ex works
  • Up to 12 immersion heaters per energy meter
  • Wireless range ~1 km free space / 2 reinforced concrete ceilings or walls


  • Optimisation of on-site consumption rate
  • Central heating backup
  • Domestic hot water heating outside the heating season (e.g. via a fresh water module)
  • Limited use with cylinders for drinking water!
  • DL bus for controlling power controllers for enhanced energy management
  • Remote access, datalogging and visualisation via C.M.I.
