DRA5U48M1B

Outdoor unit

One compressor for the whole house. It supplies up to 5 heads and modulates from 13,000 to 37,000 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.

05 · The series

09 · LogisVert grant

A grant you can calculate, not guess.

36,000 BTU/h÷ 1,000 ×$50=$1,800

The capacity at −8 °C comes from Hydro-Québec’s list of October 1, 2026. $50 per 1,000 BTU/h is the rate for ENERGY STAR heat pumps (guide v1.10).

Set for this system (AHRI 207787180). 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 zones sur un seul condenseur, et 33 000 BTU/h encore inscrits à -15 °C

Dans un immeuble de quatre logements de Villeray, la mise à niveau se fait rarement d'un coup : un logement se libère, on remplace l'appareil devenu bruyant, puis on passe au suivant l'année d'après. La Thermopompe 2-Zones DURASTAR Standard | 48 000 BTU - R410A suit ce rythme, parce qu'un seul condenseur dessert deux pièces et qu'un logement s'équipe en deux temps sans qu'une deuxième machine s'ajoute en façade.

Ses cotes sont de 21,1 SEER2, 11,0 EER2 et 9,5 HSPF2. Le système est homologué ENERGY STAR sous l'ID ENERGY STAR 4478996, chauffe jusqu'à -25 °C et figure sur la liste d'Hydro-Québec avec une subvention LogisVert de 1 800 $.

Les paliers inscrits au certificat

  • À -8 °C : 36 000 BTU/h, avec un COP de 2,50
  • À -15 °C : 33 000 BTU/h, avec un COP de 1,80
  • Limite de chauffage inscrite : -25 °C
  • Débit d'air de la tête de référence : 379 PCM

Ces valeurs proviennent du certificat AHRI 207787180, publié par le NEEP. Les cotes intérieures publiées par DuraStar, dont ce débit et le niveau sonore de 36 à 43 dB(A), décrivent la tête de référence de la fiche, non chacun des ensembles raccordables.

Ce que 33 000 BTU/h à -15 °C représentent pour deux pièces

Une nuit à -15 °C n'a rien d'exceptionnel en janvier. À ce palier, le certificat inscrit encore 33 000 BTU/h, et c'est cette valeur, plutôt que le chiffre nominal, qui sert à répartir la capacité entre les deux têtes. Les plinthes électriques passent alors au rang d'appoint, pendant que le chauffage principal travaille à un COP de 1,80 au moment où la facture grimpe.

La subvention LogisVert de 1 800 $

Ce système figure sur la liste du programme LogisVert d'Hydro-Québec, avec 1 800 $ pour un propriétaire d'une habitation existante, selon la liste en vigueur à la date d'installation. Une aide bonifiée s'applique à certains immeubles à logements multiples, ce qui vise un quatre logements. Nous validons l'admissibilité avant la signature et montons le dossier : facture détaillée, numéros de modèle et preuve de paiement. La page subvention thermopompes efficaces d'Hydro-Québec résume les conditions.

Raccorder un 2-zones dans un quatre logements de Villeray

Deux têtes, une capacité à répartir

Le condenseur DRA5U48M1B alimente deux zones, et DuraStar publie les ensembles intérieurs qui s'y raccordent : DRAS12F1A, DRAC12F1A, DRAL09F1A ou DRAD18F1A, entre autres. Les deux têtes puisent dans la même capacité : on répartit d'abord le besoin entre le salon et la chambre, puis on retient les formats qui tiennent dans l'enveloppe du système. Chaque tête garde sa commande, et fermer celle d'une chambre inoccupée laisse la seconde zone travailler.

Le tirage des lignes vers chaque tête

Chaque tête reçoit son propre jeu de lignes frigorifiques : deux parcours à planifier, pas un seul. Ils suivent la cour arrière et la descente de la galerie plutôt que les murs mitoyens. Nos installations sont entièrement apparentes, sans travaux à l'intérieur des murs, avec un recouvrement de finition sur les sections visibles de la rue. L'unité extérieure, de 37,48 x 16,34 x 52,48 pouces et mesurée à 62 dB(A), se pose sur un support ancré dans la structure, au-dessus de la ligne de neige, à l'écart des fenêtres de chambre, y compris celles des voisins.

Le circuit dédié et le panneau du logement

Le condenseur demande 220 V, un MCA de 40 A et un disjoncteur de 60 A sur un circuit dédié. Ce n'est pas le panneau de l'immeuble qui décide, mais celui du logement visé : une entrée de 100 A chargée par des plinthes, un chauffe-eau et une cuisinière laisse peu de place. Le calcul de charge précède la proposition, et toute mise à niveau est chiffrée avant la signature.

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: 36,000 BTU/h at −8 °C, 33,000 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?

$1,800 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, ID 4478996. 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 36 dB(A). Outdoors, 62 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.
