US 6,470,877 B1 · Heating apparatus

Abstract

A heating apparatus is provided which is improved in terms of its heating efficiencies over prior commercially available patio heaters. The heating apparatus includes a burner assembly housing containing a burner assembly for igniting fuel from a fuel source. The housing has a perforated wall so that the hot gases inside the housing can escape from the housing interior with the wall heating up so as to radiate infrared heat therefrom. The apparatus has a heat efficiency system which causes substantially all of the heat emanating from the housing to be used for heating of a preselected area about the apparatus. The heat efficiency system maximizes the amount of heat that is directed in a generally downward direction into the preselected area below the housing so as to minimize the heat loss and thus the amount of fuel that is necessary for heating of the preselected area.

Dependent claims

A heating apparatus for igniting fuel from a fuel tank having a control valve for controlling a supply of fuel from the tank, the heating apparatus comprising:

a heat emitter including a burner assembly for igniting fuel from the fuel tank to provide heat emanating from the emitter;
an elongate support member mounting the heat emitter at an upper end thereof and including a gas line extending therethrough for feeding fuel from the tank to the burner assembly for ignition;
and
a shroud for fitting over the fuel tank, being slidably engaged on said elongate support member for reciprocal vertical movement and including an access opening at a predetermined location on the shroud with the opening being sized to expose a portion of said fuel tank and allow an operator access to the fuel tank control valve for controlling supply of fuel to the burner assembly without sliding said shroud relative to said support.
