Baxi Duo-tec Compact 30GA in practice
The Duo-tec Compact 30GA sits in the Combi Boilers group of Baxi North America's live /products/boilers category, and its page copy positions it for large residential and light commercial applications. The official page was live with full feature bullets and current documentation on 2026-09-09, carried no discontinued banner, and is not on the official discontinued hub, so this record's productStatus is 'current'. Its page copy reads: "A compact, high efficiency gas-fired solution for central heating and domestic hot water needs." Boilers.ca records the feature bullets as printed: 93 MBH input, 95% AFUE, ENERGY STAR certified, a 5.5:1 central-heating and 7:1 DHW-mode turndown with 2.5 GPM @ 70°F temperature rise, the Stainless steel ANSI 316L pre-mixed burner and heat exchanger, a Two-speed modulating pump with built-in air vent, 15.75"(w) x 11.75"(d) x 27.5"(h) dimensions and a 79 lb weight.
No official Canadian-sales statement appears on the baxiboilers.com pages, so canadianStatus stays 'unknown'.
Vent material prints as coaxial or two-pipe polypropylene and Gas Type as Natural Gas / Propane on the official page; Baxi North America's manuals for this platform are printed for Canada/USA installers, but no Canada-specific availability wording appears on baxiboilers.com, so canadianStatus stays 'unknown' and the record exists for information and service planning. Gas, combustion and venting work on an installed unit belongs with a licensed contractor against the model's own I&O manual (posted on the official product page).
Best suited to
- Homes needing a wall-hung combi that makes domestic hot water on demand at the Duo-tec Compact 30GA rating
- Projects whose load fits the larger MP platform Baxi positions for large residential and light commercial use
- Installations that can vent in coaxial or two-pipe polypropylene per the official page

Frequently asked questions
Is the Baxi Duo-tec Compact 30GA discontinued?
No — as of 2026-09-09 the official Duo-tec Compact 30GA page on baxiboilers.com is live in the Combi Boilers category with current documentation and no discontinued banner, and the line is absent from the official discontinued hub. The discontinued Luna pages (Luna 3 Comfort, Fi, HT, Q) belong to earlier generations.
Is the Duo-tec Compact 30GA a combi or heating-only boiler?
A combi: it produces domestic hot water on demand inside the unit, and the page prints its DHW flow and DHW-mode turndown alongside the central-heating ratings.
Why does Boilers.ca show 'CHW mode' turndown on the MP models?
The official MP pages print the turndown bullet as a 'CHW mode' ratio — a typo for the central-heating mode that the research pass flagged. Boilers.ca keeps the value and records the wording as printed on the page.
