Sharp CU: four sizes, and a path to multi-zone.

Sharp’s widest wall lineup: 12,000, 15,000, 18,000 and 24,000 BTU/h. From 15,000 up, it heats down to -30°C; the 12,000, down to -27°C. Two sizes come in dark grey, and the 12,000 and 18,000 heads also connect to the CU multi-zone. We install it in Montreal, Laval, Longueuil, the South Shore and the North Shore.

The CU 12,000 stops at -27°C. The other three hold on to -30°C: the 24,000 still delivers 10,500 BTU/h there.

03 · The CU question we get most

At -8°C, the 18,000 and the 24,000 deliver exactly the same heat.

22,400 BTU/h each at -8°C, and 19,000 at -15°C, according to ENERGY STAR. So they get the same LogisVert amount: $2,688. The 24,000 stands out elsewhere: in cooling (22,000 BTU/h against 18,000) and from -20°C down, where it keeps a lead of 800 to 1,900 BTU/h depending on the temperature.

04 · Distances and multi-zone

The CU 12,000 and 18,000 heads also connect to the CU multi-zone, up to three rooms, with 25 m of line per head and 70 m in total. The CU multi-zone is coming soon to AirGreen. CHU units stay single.

05 · Heat per kWh

At -15°C, every CU gives back more than twice the electricity it uses, as heat.

1 kWh of electricity at -15°C: how much heat?

Electricity1 kWh
Heat2.2 kWh
Baseboards1 kWh

Electric baseboards: 1 kWh of heat for 1 kWh of electricity · ENERGY STAR cold-climate bar: 1.75

Coefficient of performance (COP) at -15°C according to ENERGY STAR. An electric baseboard turns all its electricity into heat, no more: its COP is 1. For cold-climate certification, ENERGY STAR requires at least 1.75 at this temperature.

06 · Quiet, in decibels

Plasmacluster

How Sharp describes its ions

1

A small electrical discharge produces positive and negative ions surrounded by water molecules.

2

On a surface, these ions combine into OH radicals.

3

According to Sharp, these radicals remove hydrogen from surface proteins, which reduces their activity.

What Sharp itself points out: its lab tests used ion concentrations far higher than the units produce, often in a one-cubic-metre box, and results vary from room to room. For its heat pumps in North America, Sharp makes no health claims: the manuals talk about released ions and a cycle that dries the inside of the unit to limit mould.
