Challenger Backboiler

1) Challenger Backboiler

The Challenger Backboiler is extremely efficient due to three unique design features:

  • back boilerSimplified straight-through flue-ways. The tapered shape is designed to extend the flame to cover the complete heat exchanger surfaces (see diagram).
  • Top water tube. This heating tube, positioned horizontally above flue-ways, collects much of the heat which would otherwise be lost into the chimney.
  • Dry-back, lift-off, radiant panel. Can rise to a higher temperature than the normal type cooled by water.


The Challenger Backboiler can be easily cleaned by lifting off the radiant panel. This allows immediate access to the unique layout of flue-ways. Bearing in mind that 1.5mm soot reduces the efficiency by up to 25%.

The Challenger allows balanced performance via the dry-back radiant panel/damper. The panel can rise to a higher temperature than one cooled by water and the increased radiant heat minimises the drop in room-heating when the damper is opened to heat water/radiators.

2) Supreme Backboiler

 

Similar in design to the Challenger, the Supreme Backboiler has a higher output due to the increased number of flueways.
