Peerless Series TCII TCII-05 in practice
The Series TCII TCII-05 is one of the fifteen current commercial cast-iron sizes in Peerless' Series TCII line. Its row in the in-page ratings table prints 1458 MBH natural-gas input (10.2 GPH / 1428 MBH oil), 1194 MBH gross output, a 896 MBH net steam rating (3733 sq ft at a 1.333 pickup factor) and a 1038 MBH net water rating (1.15 allowance), with 81.9% gas thermal efficiency and 84.4% oil thermal efficiency.
The line is built with flexible graphite port connectors and individual draw rods for a tight, secure section fit, and the official page notes that optional tankless coils can be added where domestic hot water is required. Firing is by forced-draft power burner for gas, oil or combination gas/oil applications, with catalog burner options including Beckett, Carlin, Power Flame and Riello.
Boilers.ca records the printed row for the TCII-05 for commercial service planning; no official Canadian-sales statement was found, so canadianStatus stays 'unknown', and commercial gas, combustion and venting work belongs with a licensed contractor against the Series TCII installation manual.
Best suited to
- 1458-MBH-class commercial gas loads (1194 MBH gross output)
- Large hot-water or steam systems in the 1,000+ MBH class
- Buildings that may add tankless coils for domestic hot water
