NOVAIR in Montreal: heat down to -25 °C, or down to -35 °C
NOVAIR makes two wall units that we install: the Ultra Heat series, which heats down to -25 °C, and the Hyper Heat series, down to -35 °C. Same indoor unit, from 9,000 to 24,000 BTU/h; the outdoor unit is what changes everything. At -15 °C, the Hyper Heat delivers 100% or more of its size, according to ENERGY STAR. We show you the certified numbers, then we choose with you.

01 · In deep cold
Lower the thermometer, see what’s left
Pick a size, then slide the temperature. At the three points certified by ENERGY STAR, you see the real heat output of each series. Below that, we only tell you what NOVAIR states: we don’t make up any number between the points.

This is the point that separates the two series: at -15 °C, NOVAIR writes “100% Efficiency at -15 C” for the Hyper Heat, and the ENERGY STAR numbers confirm it for every size.
Certified points: 8.3 °C (47 °F), -8.3 °C (17 °F) and -15 °C (5 °F). ENERGY STAR publishes these values from different tests; we show them as they are, without drawing a curve between them. Below -15 °C, no certified value is published for these models.

At -15 °C, the Hyper Heat 12,000 delivers 100% of its size; the Ultra Heat, 67%. The Ultra Heat holds its own when the wall unit helps an existing heating system; the Hyper Heat is made to heat on its own in deep cold. We decide with you at the estimate, based on the room and the house.
