Abstract: The present disclosure relates to portable forced air heaters and radiant heaters. Portable air forced air heaters include a blower, a blower housing, a burner disposed within the burner housing, a fuel tank in fluid communication with the burner, a fan pump and a battery connector. The battery connector of this disclosure allows for different batteries with different distinguishing features to be used.

Abstract: A fuel-fired heater can include a fuel tank; a housing assembly supported by the fuel tank, the housing assembly defining a chamber having an inlet and an air outlet; a fan located within the housing assembly; an air pump located within the housing assembly; an electric motor coupled to at least one of the fan and the air pump; a burner assembly located within the housing assembly, the burner assembly including a burner nozzle in fluid communication with the air pump and the fuel tank via a fuel line, and including an ignitor; and an electronic controller operating the electric motor and ignitor, the electronic controller including a proximity sensor oriented and arranged to sense an object located in front of the air outlet, wherein the electronic controller deactivates the electric motor when an object is sensed by the proximity sensor within a predetermined distance for a predetermined time period.

Abstract: A portable heater can include a housing including a base and an enclosure and a burner assembly disposed within the enclosure, the burner assembly including a heating surface, wherein the enclosure and the heating surface are rotatable, with respect to the base, between a first rotational position and a second rotational position. In some examples, the heating surface is a curved surface. In some examples, a tilt switch is provided that has a position that is independent of the rotational position of the enclosure. The portable heater can also include temperature control features for maintaining fuel tank temperature at an improved operating condition.
