Baxi Luna Duo-tec 1.48GA in practice
The Luna Duo-tec 1.48GA sits in the Heating Boilers group of Baxi North America's live /products/boilers category. 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: "This high efficiency modulating condensing central heating boiler is a great solution to your heating needs." Boilers.ca records the feature bullets as printed: 164 MBH input, 95% AFUE, ENERGY STAR certified, a 5.5:1 turndown in central-heating mode, the Iron-Chromium Stainless Steel Burner and Brazed Plate Heat Exchanger, a 3 speed, electronically controlled pump, 17.75"(w) x 21.5"(d) x 30"(h) dimensions and a 125 lb weight.
The official 60GA and 1.48GA pages print identical spec rows (dimensions and weight) because they are the combi and heating versions of the same platform — Boilers.ca records each page's printed rows as they appear.
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
- Heating-only systems sized to the 164 MBH input range of the Luna Duo-tec 1.48GA
- Retrofit planning against a Baxi Luna-era wall-hung platform still listed by the manufacturer
- Installations that can vent in coaxial or two-pipe polypropylene per the official page

Frequently asked questions
Is the Baxi Luna Duo-tec 1.48GA discontinued?
No — as of 2026-09-09 the official Luna Duo-tec 1.48GA page on baxiboilers.com is live in the Heating 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 Luna Duo-tec 1.48GA a combi or heating-only boiler?
A heating-only boiler: the page prints no DHW rows, so domestic hot water comes from an indirect tank or another appliance on the system.
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.
