Fits The Mannesmann lamp. The VA-burner should now light up brighter than the clay burner I could not notice, but the pressure in the lamp remains much longer constant at 2 bar. This is sure to better thermal conductivity and therefore higher temperature which are transmitted to the pipes and into the tank. Yes, the VA-burner is a safe investment in the future. 1. by the well infinite shelf life and 2. by the future shutdown of nuclear power plants where we all soon again kerosene lamps will have.
