Wall unit, 115 V or 230 V: what changes, from the electrical panel to extreme cold
One certified series, two voltages. The TOSOT PULAR R32 connects at 115 V, the TOSOT CLIVIA R32 at 208-230 V. Their seasonal ratings are identical; what separates them shows up in the electrical panel and in the certified cold-weather points.

Estimate for a 12,000 BTU/h zone in Montréal, with the same formula as on all our comparison pages. Both versions have the same SEER2 (24.5) and the same HSPF2 Region V (8.0) according to their AHRI certificates: the estimate is the same to the dollar. Going from 230 V to 115 V changes the current, not the kilowatt-hours you are billed for.
How this amount is calculated
- Heat to supply in winter : 12,000 BTU/h (3.52 kW) × 24 h × 4,167 degree-days (base 18 °C) ÷ (18 − (−23.1 °C)), prorated to the heating hours you choose. Degree-days and design temperature: Natural Resources Canada, HOT2000 climate map, Montréal International station. At 24 h a day: 8,558 kWh of heat.
- Heat pump electricity : heat × 3.412 ÷ HSPF2 Region V from the AHRI certificate (8.0 for both). Region V includes the electric backup set by the standard.
- Electric baseboards : 1 kWh of electricity per kWh of heat.
- Cooling : 12,000 BTU/h ÷ SEER2 (24.5 for both) × hours per day × 60 days ÷ 1,000, the method of Hydro-Québec’s air-conditioning calculator.
- Price : Hydro-Québec Rate D in effect on April 1, 2026, taxes (GST and QST) included; system access charge excluded.
Two simplifications: fewer heating hours reduce the heat pro rata, without counting the recovery after a temperature setback; 24 h of cooling assumes rated capacity all day, which is a maximum, since a variable-speed unit slows down. The result is an estimate, not a bill.
One pole or two: click a breaker
In a 120/240 V residential panel, a 115-120 V circuit goes through a single-pole breaker; a 208-230 V circuit needs a two-pole breaker, so two spaces. Pick a breaker to see the unit it feeds and what the manufacturer’s sheets publish for its circuit.
Why 115 V draws more amps. Electrical power is voltage times current. For the same power, a voltage half as high carries about twice the current. The bill follows kilowatt-hours, which is why the cost estimate is the same for both versions.
Four temperatures, two versions
NEEP publishes certified heating capacities at 8.3 °C, −8.3 °C, −15 °C and −30 °C. At 8.3 °C, both versions are identical. At −8.3 °C, the 115 V has the higher rated capacity (11,000 vs 10,000 BTU/h) and the 230 V the higher maximum (12,000 vs 11,200). At −15 °C and −30 °C, the 230 V publishes more capacity.
Below −15 °C: every certified point
In Montréal, the January mean is −9.2 °C and the building design temperature is −23 °C. NEEP certifies both versions at −15 °C and at −30 °C, the same temperatures, so the values compare directly. In between, no point is certified; the page shows the range between the two published values.
What people ask us about 115 V
Does the 115 V version cost more to run?
According to the AHRI certificates, no: SEER2 24.5 and HSPF2 9.5 / 8.0 for both. With our method, the estimate is the same. The difference is electrical: more amps at 115 V, for the same kilowatt-hours.
Can it be plugged into an existing outlet?
The series’ 115 V submittal sheet describes a power supply wired to the outdoor unit, with no mention of a plug. The circuit is determined from the unit’s nameplate, by a master electrician, under the Québec Construction Code.
My panel has few free spaces. Which version takes the least room?
A single-pole breaker takes one space; a two-pole breaker takes two. The panel’s remaining capacity is checked before the work, by a master electrician.
Why does the 230 V publish more capacity at −15 °C?
NEEP certifies 11,000 BTU/h for the CLIVIA 208-230 V and 9,500 BTU/h for the PULAR 115 V at −15 °C, with the same COP of 1.95. The manufacturer does not explain this gap in the documents we consulted; we do not interpret it.
Are they sold under other names?
Yes. The TOSOT CLIVIA R32 12,000 (115 V) uses the same outdoor unit as the PULAR 115 V (TW12HP32A2AO), with the same certified values except the rated capacity at −8.3 °C; the KINGHOME CLIVIA R32 12,000 (115 V) has the same NEEP certified values as the TOSOT CLIVIA 115 V. On the 230 V side, the KINGHOME CLIVIA R32 12,000 (220 V) belongs to the same NEEP series, with small differences. Our page on the Clivia platform compares them value by value.
Which one to choose?
This page does not rank the units. It shows what the certificates and spec sheets publish; the choice depends on your panel, the circuit that can be run and the heat the room needs in extreme cold.
Are they eligible for grants?
Eligibility depends on the program, its official list on the purchase date and the exact unit. This page promises no amount.

Where every number comes from
Data verified on November 9, 2026. This guide explains the difference between a 115 V wall unit and a 208-230 V wall unit; it ranks neither the units nor the brands. Efficiency and capacity values: AHRI certificates published by NEEP. Electrical and installation: manufacturer sheets for units in the same NEEP series; when a source contradicts the AHRI certificate, the certificate prevails, and the nameplate of the delivered unit governs for the circuit.
Estimated cost. AirGreen estimate using the method described above, identical on all our comparison pages; it is not a bill.
