Bosch have developed the Compact Internal (CI) unit as a replacement for the WR range of internal water heaters.
The CI range has the following features:
  • Designed for convenience, as the heater is ready to operate by simply pressing a switch.
  • Heater for internal wall-mounting.
  • Ignition by electronic device triggered when a hot water tap opens.
  • Hydrodynamic generator which produces sufficient energy to ignite and control the heater.
  • Gauge to display temperature, burner operation, and error codes.
  • Temperature sensor to monitor the water temperature at the heater outlet.
  • Available in Natural gas or LPG.
  • Temporary pilot light which only functions during the period between the opening of the water valve and the ignition of the main burner.
  • Water valve in fibreglass-reinforced polyamide, 100% recyclable.
  • Automatic control of the water flow to allow for variable supply pressure.
  • Gas flow adjustment proportional to the water flow to maintain a constant temperature.
  • Safety Devices
    • Ionisation probe to check for accidental extinction of the burner flame.
    • Flue gas safety device which turns off the heater in cases where the evacuation of flue gases is inadequate.
    • Temperature limiter which prevents overheating of the heat exchanger.
