DRA5H36M2A

Outdoor unit

One compressor for the whole house. It supplies up to 5 heads and modulates from 10,000 to 38,500 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.

38,500 BTU/h÷ 1,000 ×$120=$4,620

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 215359221). 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.

Deux agrandissements, deux zones : où couper un bungalow en deux

Un bungalow agrandi à deux reprises n'a plus la logique thermique de ses plans d'origine. La première rallonge a souvent gardé le chauffage du corps principal, la seconde a reçu ses propres plinthes, et l'ensemble se comporte comme deux maisons collées. Dans Villeray, ces bungalows sont nombreux, et c'est souvent le montant d'une subvention qui décide du moment où l'on reprend le tout. La Thermopompe 2-Zones DURASTAR Sirius Heat | 36 000 BTU - R454B permet de tracer cette coupure au bon endroit plutôt que de chauffer tout d'un seul point.

Un HSPF2 de 11,3 et le reste du certificat

  • Rendement saisonnier : 21,5 SEER2, 12,2 EER2 et 11,3 HSPF2
  • À -8 °C : 38 500 BTU/h, COP de 2,37
  • À -15 °C : 37 000 BTU/h, COP de 1,90
  • À -30 °C : 23 800 BTU/h, COP de 1,55
  • Homologation ENERGY STAR, ID ENERGY STAR 3621116, désignation climat froid, chauffage jusqu'à -30 °C

Le 11,3 HSPF2 est la cote saisonnière de chauffage : elle résume une saison entière plutôt qu'un point isolé. Dans un bungalow où la thermopompe porte l'essentiel de l'hiver sur deux volumes distincts, c'est elle qui pèse le plus lourd. Ces valeurs proviennent du certificat AHRI 215359221, publié par le NEEP.

Le zonage d'un bungalow agrandi deux fois

La coupure ne suit pas les murs d'origine mais les usages : d'un côté le corps principal avec les chambres, de l'autre la rallonge la plus exposée. Les 36 000 BTU/h du condenseur DRA5H36M2A se partagent entre les deux têtes selon la consigne de chacune, et arrêter la rallonge en hiver ne coupe pas le corps principal. Les têtes se prennent parmi DRAS12F2A, DRAS16F2A, DRAC24F2A, DRAM18F2A, DRAF24F2A, DRAL18F2A et les autres modèles publiés ; le châssis accepte jusqu'à 5 zones.

La subvention LogisVert de 4 620 $

Cet ensemble donne droit à 4 620 $ au programme LogisVert pour un propriétaire d'une habitation existante, sous l'ID ENERGY STAR 3621116. Le montant dépend de la liste en vigueur à la date d'installation, et une aide bonifiée s'applique à certains immeubles à logements multiples. La page de la subvention thermopompes efficaces d'Hydro-Québec détaille les conditions, et nous validons l'admissibilité avant la signature.

Coordonner la pose quand la cour et les murs ne sont pas entièrement à soi

Les accords à obtenir avant de percer

Un bungalow agrandi se retrouve souvent à quelques pieds de la limite de terrain, et certaines de ces propriétés sont détenues en copropriété divise. Quand c'est le cas, le mur extérieur et la cour sont des parties communes et le syndicat doit approuver l'ancrage et l'emplacement. Nous préparons cette demande avec le gabarit de 31,69 x 12,99 x 21,81 pouces et la cote de 55 dB(A).

Les têtes, le condenseur et les lignes

Le condenseur se pose au-dessus de la ligne de neige, à distance des fenêtres de chambre, y compris celles des voisins. Chaque tête reçoit sa paire de lignes frigorifiques, son drain et son câble de commande. Nos installations sont entièrement apparentes, sans travaux à l'intérieur des murs, avec un recouvrement de finition. Le raccordement demande 220 V, un MCA de 15 A, un disjoncteur de 15 A et un circuit dédié, précédé du calcul de charge.

Ce qui est normal une fois le système en route

Deux volumes très différents sur un même condenseur donnent des comportements décalés.

  • La tête de la rallonge souffle plus longtemps que l'autre : ce volume perd sa chaleur plus vite.
  • Un délai de trois minutes au redémarrage protège le compresseur.
  • De la vapeur blanche accompagne le dégivrage du condenseur.
  • Le chauffage cesse sous -30 °C.

Une odeur de brûlé, un disjoncteur qui saute, un code d'erreur persistant ou de l'eau qui coule à l'intérieur demandent d'arrêter l'appareil et d'appeler le service. Les filtres se rincent aux deux semaines et un entretien CVAC annuel couvre serpentins, condensat et raccords électriques.

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: 38,500 BTU/h at −8 °C, 37,000 at −15 °C.

How many heads can I connect?

Up to 5 on this outdoor unit. This product is configured for 2 heads.

How much is the LogisVert grant?

$4,620 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 3621116. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.

Down to what temperature does it heat?

Down to −30 °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.
