Abstract
A portable heater includes a housing defining a base portion and a radiant heating assembly positioned within the housing. The radiant heating assembly includes a connector configured to receive a fuel tank having a combustible fuel, an ignition assembly configured to ignite the combustible fuel, and a radiant heating surface configured to be heated by ignition of the combustible fuel. The radiant heating surface is configured to emit radiant energy to a surrounding environment. An air flow channel is formed in the housing defines an intake opening and an exhaust opening. The exhaust opening is positioned proximate the radiant heating surface. A fan is positioned within the air flow channel to induce an airflow through the air flow channel. The airflow exits the exhaust opening to disperse the radiant energy from the radiant heating surface to the surrounding environment.
