Triangle Tube Challenger CC85 Solo

The Challenger CC85 Solo is the smallest Challenger heating-only boiler, firing 23 to 84 MBH at 94% AFUE with a 3.7:1 turndown — a condensing solo for use with an indirect tank, discontinued years before the November 3, 2025 cessation.

Triangle Tube Challenger CC85 Solo in practice

The CC85 Solo opens the Challenger solo range at 23 to 84 MBH of input, rated 94% AFUE with a 3.7:1 turndown, 75 MBH DOE capacity and a 65 MBH net AHRI rating. The submittal code CC85 confirms the model identity behind the 'Challenger 85s' row of the archived 2019 comparison table.

As a heating-only solo it was paired with an indirect water heater such as the Smart line, sharing the Challenger's dual-material heat exchanger with aluminum heat transfer and glycol-compatible copper waterways. Challenger pages were removed from the live site years before the company ceased operations in November 2025, so archived pages and the official manuals remain the documentation for the installed base.

Best suited to

  • Owners identifying a CC85-prefixed Challenger solo from its rating plate
  • Small homes whose original heat-loss load matched an 84 MBH ceiling
  • Service work referencing the Challenger Solo installation manual and user guide
