DRA6U48M2A

Outdoor unit

One compressor for the whole house. It supplies up to 6 heads and modulates from 13,000 to 36,800 BTU/h depending on what the rooms call for (NEEP).

03 · How it works

Turn rooms on and off. Watch the power being shared.

One outdoor unit supplies every head: when several rooms call at once, they share its capacity. Pick an outdoor temperature.

04 · My plan

Tell us your rooms. We tell you if this size is enough.

Pick the number of rooms and their size. The estimate targets a −15 °C day; it is a guide, the real calculation is done room by room at your home.

09 · LogisVert grant

A grant you can calculate, not guess.

36,800 BTU/h÷ 1,000 ×$120=$4,416

The capacity at −8 °C comes from Hydro-Québec’s list of October 1, 2026. $120 per 1,000 BTU/h is the rate for ENERGY STAR cold-climate heat pumps (guide v1.10).

Set for this system (AHRI 215415538). Another head combination (ducted, console) can change the AHRI number, and so the amount.
Cap: the grant never exceeds 100 % of the purchase and installation cost before taxes.
9 months after installation to apply; +5 % when two measures are in the same request.

Everything we have written about this system.

L'atelier attenant compte dans la charge, même s'il n'est chauffé qu'à moitié

À Chambly, une résidence avec atelier attenant se calcule en deux temps : la partie habitée, tenue à température constante, et l'atelier, chauffé séparément et seulement quand on y travaille. Ces deux parties partagent souvent un mur et toujours le même bâtiment. Quand un déménagement est déjà prévu pour l'été suivant, le calcul doit tenir dans les deux configurations. La Thermopompe 5-Zones DURASTAR Standard | 48 000 BTU - R454B traite l'atelier comme une zone à part entière.

Ses cotes sont de 21,3 SEER2, 11,7 EER2 et 10,0 HSPF2. Le système est homologué ENERGY STAR avec la désignation climat froid sous l'ID ENERGY STAR 3624611, chauffe jusqu'à -30 °C et donne droit à une subvention LogisVert de 4 416 $.

Calculer la charge avant d'arrêter le format

Notre point de départ reste d'environ 18 000 BTU/h par 1 000 pieds carrés, ajusté selon l'isolation, la fenestration, la hauteur des plafonds et l'ouverture entre les pièces. Un atelier attenant déplace ce calcul dans les deux sens : ses plafonds sont plus hauts et son isolation plus mince, mais il n'est pas tenu à la même température que les chambres. Les cinq zones se partagent la capacité du condenseur DRA6U48M2A, et les têtes se choisissent parmi les ensembles compatibles publiés par DuraStar, dont DRAS12F2A, DRAM18F2A et DRAC24F2A.

Les paliers certifiés de cet ensemble de 48 000 BTU

  • À -8 °C : 36 800 BTU/h, avec un COP de 2,40
  • À -15 °C : 36 000 BTU/h, avec un COP de 2,10
  • À -25 °C : 20 000 BTU/h, avec un COP de 1,20
  • Limite de chauffage inscrite : -30 °C

Ces valeurs proviennent du certificat AHRI 215415538, publié par le NEEP. L'écart entre -8 °C et -15 °C est faible, 36 800 contre 36 000 BTU/h : la capacité disponible ne s'effrite pas à mesure que l'hiver s'installe, ce qui compte quand une zone doit réchauffer un atelier laissé froid plusieurs jours. Les cotes intérieures publiées, 418 PCM et de 24 à 43 dB(A), valent pour une tête de référence.

LogisVert : le montant rattaché à ce système

Le système figure sur la liste du programme LogisVert d'Hydro-Québec, avec 4 416 $ pour un propriétaire d'une habitation existante, selon la liste en vigueur à la date d'installation, et une aide bonifiée s'applique à certains immeubles à logements multiples. Nous confirmons l'admissibilité avant la signature et préparons la facture détaillée, les numéros de modèle intérieur et extérieur et la preuve de paiement, de façon que le dossier soit clos avant votre départ.

Chambly : une seule alimentation pour la maison et l'atelier

Un MCA de 15 A, et ce que cela libère au panneau

La fiche inscrit 220 V, un MCA de 15 A et un disjoncteur de 15 A sur un circuit dédié. Sur un bâtiment qui comporte déjà un atelier, souvent équipé de son propre sous-panneau et d'outils gourmands, ce calibre modeste change la discussion. Nous refaisons malgré tout le calcul de charge complet, atelier inclus, et annonçons toute mise à niveau avant la signature.

L'unité extérieure entre la maison et l'atelier

Le bon emplacement est rarement celui qu'on imagine : posée entre les deux volumes plutôt qu'au bout de la maison, l'unité extérieure de 31,69 x 12,99 x 21,81 pouces équilibre les longueurs de lignes. Mesurée à 55 dB(A), elle se fixe sur un support ancré dans la structure, au-dessus de la ligne de neige, avec l'élément chauffant de bac de série et à distance des fenêtres de chambre.

Les lignes vers l'atelier, la plus longue des cinq

La zone de l'atelier reçoit le parcours le plus long, et c'est elle qu'il faut tracer en premier. Chaque tête garde son propre jeu de lignes et son propre écoulement de condensat. Les installations restent entièrement apparentes, sans travaux à l'intérieur des murs. Couper la zone de l'atelier pendant la semaine n'arrête aucune des quatre zones de la maison.

19 · Questions

What people ask us about multi-zone systems.

Can I heat one room and cool another at the same time?

No. On a multi-zone system like this one, every head works in the same mode, heating or cooling. Each room still keeps its own set temperature.

What happens when every room calls for heat?

They share the outdoor unit’s capacity: 36,800 BTU/h at −8 °C, 36,000 at −15 °C.

How many heads can I connect?

Up to 6 on this outdoor unit. This product is configured for 5 heads.

How much is the LogisVert grant?

$4,416 according to Hydro-Québec’s list of October 1, 2026. The grant never exceeds 100 % of the cost before taxes; apply within 9 months of installation.

Is it ENERGY STAR certified?

Yes, cold climate, ID 3624611. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.

Down to what temperature does it heat?

Down to −25 °C.

Is it noisy?

Indoors, the reference head goes down to 24 dB(A). Outdoors, 55 dB(A): we place the unit away from bedroom windows.

Why a multi-zone instead of several wall units?

One outdoor unit on the wall and one circuit. In return, the rooms share the capacity, and if the outdoor unit stops, every zone stops.

What does the warranty cover?

Our sheet lists 10 years on the compressor and 10 years on parts. AirGreen extended warranty: possible.
