How do I empty the Truma electric boiler properly?

If the caravan is not being used during the frost period, the Truma electric boiler must be drained.

To prevent frost damage:

  • Disconnect the power to the water pump (main switch or pump switch).
  • Open hot water taps in the bathroom and kitchen.
  • Open drain valve: lever vertical, position (b).
  • The Truma electric boiler will now be drained directly to the outside via the drain valve. 
  • Check whether all the water is drained (14 litres).


Remember that we do not accept warranty claims for frost damage.
