effiQueenc air-to-water heat pumps: split or monobloc, down to -30 °C

effiQueenc is a Québec maker of hydronic systems, based in Saint-Jules. At AirGreen, two 5-ton R-410A air-to-water heat pumps: the split (outdoor unit plus an indoor hydrobox) and the monobloc (all the refrigerant stays outside). Both run down to -30 °C according to the manufacturer, and both heat the house through water.

Split: the refrigerant travels to the hydrobox inside the house, over 35 ft at most according to effiQueenc. The water never goes outside.

01The lineup

Two effiQueenc units, one size: 5 tons

Same size, same refrigerant, same cold limit. What changes is where the water gets heated: inside the house with the split, outside with the monobloc.

The numbers, as charts

Output, BTU/h conversion and noise: the values effiQueenc publishes, side by side so the difference shows at a glance.

Published output ranges (kW)

The black tick marks the split’s nominal value. For split cooling, the web page and the brochure give different ranges.

Outdoor unit noise

Values published by the manufacturer, in dB(A).

Converter kW → BTU/h → tons

effiQueenc publishes in kW; in Québec people often talk in BTU/h and tons.

17kW
58,000BTU/h
4.8tons

“5 tons” is the manufacturer’s designation (5 × 12,000 = 60,000 BTU/h). The published nominal heating of the split is 17 kW.

Conversions: 1 kW = 3,412 BTU/h; 1 ton = 12,000 BTU/h; 1 ton of refrigeration = 3.517 kW. The monobloc’s cooling range is published in tons of refrigeration (1.8 to 4.7) and converted here to kW.

AirGreen × effiQueenc

A heat pump from here, a team from here.

effiQueenc designs air-to-water heat pumps for our winters. AirGreen comes to see the house, picks the split or the monobloc with you, and installs it. Each does what it does best.

03Split or monobloc

Distance first, then three questions

Every answer relies on what the manufacturer publishes for these two models. Nothing to fill in, nothing is sent.

Distance between the outdoor unit and the mechanical room25 ft · 7.6 m

35 ft or less: both models remain possible.

Refrigerant inside the house?

The monobloc keeps all the refrigerant outside.

Will the outdoor unit be near a bedroom or a neighbour?

50 dB(A) for the split, 54 dB(A) for the monobloc, per the manufacturer.

Water in pipes that run outside in winter?

With the split, the water stays inside; the monobloc has a frost mode.

04How it heats

The heat travels through water

An air-to-water heat pump does not blow air into the house. It heats water, and that water heats the rooms.

  1. 1

    Capture

    The outdoor unit pulls heat from the air, even in deep cold: down to -30 °C per effiQueenc.

  2. 2

    Pass it to water

    In the split’s indoor hydrobox, or directly in the monobloc, outside.

  3. 3

    Store

    effiQueenc recommends its energy-storage tank to boost the performance of most hydronic systems.

  4. 4

    Heat the rooms

    The hot water flows to the radiant floor, the radiators or fan coils.

Water temperatures published by effiQueenc

The manufacturer publishes two different ranges: its web page and its 2021 brochure. Both stop at 55 °C for heating.
