Abstract: This is an upright heater igniting combustible gas to induce a naturally aspirated flame within a glass tube. Air channels producing the naturally aspirated flame enters the glass tube in a direction perpendicular to the direction of the flame thus creating a twirling flame. Heat waves generated by the twirling flame within a glass tube rises to a heat concentrator and projected onto a parabolic heat shield thus reflecting the heat wave radially downward and outward.
