obviously I'm doing something wrong. When I put the pillow into the water (which I have previously brought on the stove or in the kettle for cooking) and out hole after 15 minutes, the pillow is at best warm. No comparison to the hot water bottle or Körnerkissen (Which, unfortunately, very quickly gives off heat). But I know that a Moor Pillow can reach these temperatures, an appropriate warning is also added to the manual. Also an extension to 20 minutes does not have any other result rendered ..
Maybe someone knows advice here? Thanks in advance!
