Senville concealed-duct heat pumps

A unit hidden in the ceiling or a bulkhead, a few grilles, and nothing on the wall. Senville writes “Concealed Duct” (“Conduit Caché” in French); in Quebec it is called a gainable. Here are its four ducted units: their dimensions and airflow, how high the condensate can be lifted, what Senville does and does not publish about static pressure, and their certified figures for winter and for LogisVert.

01 · What the duct can push

Static pressure: what Senville publishes, and what it does not

A ducted unit blows into ducts and grilles that hold the air back: that is external static pressure. Senville publishes it for none of its four ducted units. The schematic gathers everything that is published around it: fan settings, airflow, filter and condensate.

NEEP lists all four systems as “Singlezone Ducted, Compact Ducted”.

Before quoting: published or not

The fifteen points an installer checks before proposing a ducted unit, and what Senville actually says about each.

  • Indoor unit dimensions and weightPublished

    All four capacities; millimetres confirmed by the installation manual for the 9,000 to 18,000. See table 02.

  • Supply and return openingsUnreadable

    Given in the installation manual for the 9,000 to 18,000, but the table does not read cleanly: sizes not confirmed.

  • Airflow, four speedsPublished

    Turbo, high, medium, low, for each capacity, with no static pressure attached.

  • Rated external static pressureNot published

    No value, for any capacity.

  • Maximum static pressureSeries only

    160 Pa and 200 Pa in the service manual, which also covers 36,000 to 60,000 BTU/h units; nothing aimed at these four models.

  • Fan settingsPublished

    SP1 by default; SP1 to SP4 for the 9,000, 12,000 and 18,000.

  • Condensate pumpNot published

    The series manual only says pump models exist.

  • Lift pipe heightContradictory

    55 cm (service manual) or 70 cm (installation manual).

  • Drain slopeContradictory

    At least 1/100, or 1/50 on another page of the installation manual; 1/50 satisfies both.

  • FilterPublished

    Optional, in the return flange, with no filtration rating.

  • Line set sizesNot published

    Missing from the spec tables; installation manual table unreadable.

  • Max. length and dropPublished

    Both manuals agree. See table 02.

  • Power, ampacity, fusePublished

    208/230 V single-phase, 187 to 253 V. See table 02.

  • Control suppliedContradictory

    “Remote Control” (9,000), “Wired Control” (12,000 to 24,000), “Wireless Remote Control” in the box list.

  • Indoor unit soundPublished

    Three or four values per capacity, under inconsistent speed labels; test conditions not published.

Certified values: ENERGY STAR and NEEP; LogisVert amounts: Hydro-Québec’s file; read October 14, 2026, re-checked unchanged October 26, 2026. The rest: senville.ca spec tables, October 14, 2026, and installation manual QS004I-T2(R454B), October 26, 2026. The tables print sound under inconsistent speed labels (three values under “H/M/L”, four for the 24,000): we show the loudest and the quietest. The series service manual gives a 1,000 mm width on a row shared by the 18,000 and 24,000, but the 18,000 installation manual says 880 mm, like the spec table: we keep 880 mm. We leave out two faulty table lines (the truncated “SENA-18HF” model, the 24,000’s “4.~10.6” current). At 12,000 BTU/h, with the same SENA-12HF-OG outdoor unit, the ducted unit has a SEER2 of 20; the AURA wall unit, 25.4. Senville warranty as printed on senville.ca. Warranty terms

Same footprint on paper, not the same certified figures

The 9,000 and 12,000 spec tables print the same dimensions, weight, airflow and ranges; the installation manual puts them on one dimension row. Senville does not say whether they are the same unit. Their certificates, though, set them clearly apart.

Questions

Ducted units: codes, pressure, water, control, certificate

SENA/12HF/ID or SENA-12HF-IDG: what does each code stand for?

SENA/12HF/ID is the name of the complete system on senville.ca (“Conduit Caché” in French). SENA-12HF-IDG is the indoor unit, paired with the SENA-12HF-OG outdoor unit on the AHRI certificate, the ENERGY STAR record and Hydro-Québec’s list; installation manual QS004I-T2(R454B) gives the same pairs for the 9,000, 12,000 and 18,000. One exception: the help-centre article devoted to model numbers still files the ducted units under SENA-09HFMO-IDZ16 to SENA-24HFMO-IDZ16, codes that appear on no certificate.

Question published by Senville: “What are the wall mount, cassette, duct, and floor unit model numbers?”, help centre, modified October 8, 2026, read October 26, 2026; manual QS004I-T2(R454B), read October 26, 2026.
How much static pressure can a Senville ducted unit handle?

Senville does not publish it for any of its four ducted units. The installation manual for the 9,000, 12,000 and 18,000 files them under the “Low static pressure series” and limits the fan to settings SP1 to SP4 (SP1 by default), with no value in pascals. The series service manual quotes 160 Pa and 200 Pa, but for “MSP” and “HSP” models of a range that goes up to 60,000 BTU/h: we do not apply those figures to these units. With no published value, duct length and layout are checked job by job.

Installation manual QS004I-T2(R454B), read October 26, 2026; service manual SM_A7 DUCT(GA)_R454B_3D INV_US1_NA_2402 and senville.ca spec tables, read October 14, 2026.
How high can the condensate be lifted?

Senville’s two manuals give different limits: 55 cm above the ceiling in the service manual, 70 cm in the installation manual for the 9,000 to 18,000, with the lift pipe within 20 cm of the unit. We use 55 cm, which satisfies both. The drain slope ranges from at least 1/100 to 1/50 depending on the page; its outlet stays at least 5 cm above the ground. Senville does not publish, capacity by capacity, whether the pump is included.

Service manual SM_A7 DUCT(GA)_R454B_3D INV_US1_NA_2402, October 14, 2026; installation manual QS004I-T2(R454B), October 26, 2026.
Which control comes with a ducted unit?

Senville’s documents contradict each other. The 9,000 table says “Remote Control”, the 12,000, 18,000 and 24,000 tables say “Wired Control”, and each system’s box list announces a “Wireless Remote Control”. The service manual lists a wired controller among the supplied accessories, then elsewhere says “Remote Controller (purchase separately)”. The quote states which control is planned.

Why does the certificate linked on senville.ca for the 12,000 not match?

On October 14, 2026, the senville.ca SENA/12HF/ID page linked AHRI number 205921391. The certificate Senville hosts for the SENA-12HF-OG and SENA-12HF-IDG pair is number 215735301 (cooling 12,000 BTU/h, SEER2 20.00, EER2 12.00, heating 12,500 BTU/h, HSPF2 region IV 10.00), the same as ENERGY STAR record 3630048, NEEP and Hydro-Québec. We show 215735301. That certificate also appears under a file named “SENA-12HF-IFG”, dated 12-12-2025 instead of 01-08-2026.
