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.

The present disclosure is directed to a multi-heat source apparatus. The multi heat source may include a fire pit and is configured to provide ambient heating with both convection heat transfer and radiation heat transfer. The multi-heat source apparatus comprises an infrared emitter for generating infrared radiation. The multi-heat source apparatus comprises a shielding member between a heat source for the convection heat transfer and another heat source for radiation heat transfer.
