Winter time. What do I have to observe?

There are several possibilities to avoid the complete freezing through:

  • Heat up the furnace from time to time
  • Use a heating cable and temperature sensor to prevent the freezing
  • Empty your wood burning Hot Tub
  • Styropor in the water – water presses styropor together in this case what in turn avoids that the Hot Tub is damaged. However the volume has to be calculated precisely.
  • Use a filter pump in the hot tub to circulate the water
