The REKA round and big bale boilers is placed on a brick foundation with grate and ash storage. To facilitate the ash removal in the long boiler an extra ash removal door can be built into the side o0f the brick foundation. The tube system on the side of the boiler controls the air supply and ensures an even combustion.

NOTE! To obtain a complete combustion the fire must be lighted at the top of the straw bale.

The ashes fall down into the ash storage and can be removed according to requirement.

This ensures that the boilers is always empty when a straw bale is to be introduced.
