Catalytic water heater for brewing tea or coffee burns gas supplied from small pressure bottle and has integral piezoelectric igniter

摘要

Gas is stored in cylindrical bottle (10) fastened by straps (9) to the vessel (8) containing water. Gas flows through pipe (11), clamped (13) to the vessel, to a catalytic burner (4) with a horizontal water heating plate (2) above an open space to carry off the combustion gases. Piezoelectric igniter (5) is integral with the burner assembly, and a gas flow control valve (12) on the top of bottle.
