Abstract
A radiant heater includes a generally U-shaped radiative heating element having a first straight section, a second straight section, and an interconnecting U-shaped section. The non-connected end of the first straight section is arranged for communication with a burner and the non-connected end of the second straight section is arranged for communication with an extractor for extracting combustion gases from the tube. A redirecting element including opposed helical vanes, each executing a 180° turn about a central, common tube, is arranged within the first straight section so as to redirect, in use, at least a portion of the combusted gases flowing within the upper half of the tube towards the lower half, and gases flowing in the lower half towards the upper half.
Claims17
A radiant heater comprising:
- a radiant heating element in the form of a tube having first and second ends;
- a burner communicating with a first end of the tube for delivering combustion gases into the tube;
- an extractor communicating with the other, second end of the tube for extracting combustion gases from the tube;
- and
- a redirecting element arranged so as to redirect, in use, at least a portion of the combustion gases flowing within the upper half of the tube towards the lower half.
A radiant heater comprising:
- a generally U-shaped radiative heating element having a first straight section, a second straight section, and an interconnecting U-shaped section, the non-connected end of the first straight section being arranged for communication with a burner and the non-connected end of the second straight section being arranged for communication with an extractor for extracting combustion gases from the tube;
- and a redirecting element arranged within the first straight section so as to redirect, in use, at least a portion of the combustion gases flowing within the upper half of the tube towards the lower half.
A method of providing a heating element, comprising:
- providing a heating element formed of first and second detachable tube sections;
- separating the first and second sections to reveal an opening in each section;
- inserting a redirecting element within at least one of the sections through its opening, the redirecting element comprising a support member carrying at least one curved vane which in use is arranged to re-direct a combusted gas travelling through the tube section from an upper region to a lower region;
- and reconnecting the separated first and second sections.
