<p>A toilet system is provided comprising a combustion chamber with an electric combustion device comprising an electric heating coil (30). The toilet system is characterized in that the electric heating coil has the shape of a cone. By providing a cone-shaped heating coil, a turbulent air flow is created, which penetrates the electric heating coil along its entire length. No part of the electric heating coil will be in the "shadow" of the air flow and the heat transfer efficiency will be high.</p>
