Ouellet OAC04000AM-T Commercial Wall Fan Heater 4000W 240/208V, Almond

The Ouellet OAC04000AM-T is a commercial wall fan heater rated 4000 / 3000 W at 240 / 208 V, finished in almond. It is the commercial workhorse - a heavy-gauge fan-forced wall heater for shops, warehouses, stairwells, garages and vestibules where a residential unit would not survive the duty cycle.

TL;DR

• Output: 4000 / 3000 W at 240 / 208 V (13,660 / 10,250 BTU/h)
• Draw: about 16.7 A - size the circuit at 125% per CEC 8-104
• Finish: Almond
• Control: built-in thermostat
• Availability: in stock in Vaughan, ON. Ships Canada-wide, counter pickup available

Quick Specs

Best For

• Shops, garages, warehouses and mechanical rooms
• Commercial entry vestibules and stairwells
• Loading docks and back-of-house spaces on 208 V or 240 V services
• Buildings replacing gas unit heaters as the gas line comes out

Why Contractors Choose It

• 2000 W to 4000 W from a single wall-mounted unit - no suspended mounting required
• Heavy-gauge enclosure and commercial-duty motor built for continuous cycling
• Built-in thermostat models remove a separate control run
• Offered across 208 V, 240 V and 347 V so it lands on whatever service the building has

Choose the Right Model

Ouellet builds this series across the wattages and supply voltages Canadian buildings actually run. Match the part number to the service you have:

• OAC04000BL - white
• OAC04008BL-T - 208 V, white
• OAC03000BL-T - 3000 / 2250 W, white
• OAC02008BL-T - 2000 W, 208 V, white
• OAC02000BL - 2000 / 1500 W, white
• OAC02000BL-T - 2000 / 1500 W, white

Installation Notes

CEC Section 62 governs the install; CEC 8-104 sets conductors and breaker at 125% of nameplate. Commercial units on 208 V or 347 V feeders must land on the correct phase configuration - confirm the building supply before ordering. A disconnecting means is required per CEC 62-108.

Common Mistakes to Avoid

• Ordering 240 V for a 208 V building service and losing 25% of the rated output
• Skipping the disconnecting means required by CEC 62-108
• Mounting too low - commercial fan heaters are designed to throw from height
• Undersizing the branch circuit; these are continuous loads sized at 125%

Frequently Asked Questions

Is the Ouellet OAC04000AM-T CSA certified for use in Canada?
Ouellet is a Quebec manufacturer and its heating products are built to Canadian standards and certified for the Canadian market. Confirm the certification mark and the ratings on the unit's own nameplate against your local amendments before you energize it.

Where does Maple Electric Supply ship this from?
From our own stock in Vaughan, Ontario. That means no cross-border wait, no duty and no surprise brokerage on a heater you need before the cold hits. Counter pickup is available, and we ship across Canada.

What does the 4000 / 3000 W rating on the OAC04000AM-T actually mean?
This unit is dual-rated. On a 240 V supply it delivers 4000 W. Put the same unit on a 208 V supply and output drops to about 3000 W - roughly 75%, because output falls with the square of the voltage. Order on the voltage the building actually has, not the one on the drawing.

What size breaker and wire does the OAC04000AM-T need?
The unit draws about 16.7 A at 240 V. Fixed electric heat is a continuous load, so CEC 8-104 sizes the conductor and the breaker at 125% of that - about 20.9 A. Your electrician sizes the final circuit against everything else on it; a 15 A 240 V circuit tops out at 2880 W of total connected heat.

How much heat is 4000 W in a real room?
13,660 / 10,250 BTU/h. As a working rule of thumb for an insulated Ontario room, budget roughly 10 W per square foot for a well-insulated space and closer to 15 W per square foot for a basement, a room over a garage or anything with a lot of glass. Send us the dimensions and we will size it properly.

Does the OAC04000AM-T need a separate wall thermostat?
No. This model ships with a built-in thermostat - the control is in the unit, so you skip the wall box, the control run and the separate device. If you would rather run a wall stat for a multi-heater zone, order the version of this part number without the built-in control.

Do I need a disconnect for this commercial heater?
Yes. CEC 62-108 requires a disconnecting means for fixed electric heating equipment - within sight of the unit, or lockable in the open position. On a suspended or ceiling-mounted unit that is not optional and inspectors look for it.

Can this replace a gas unit heater?
Often, yes - and it removes the venting, the gas piping, the combustion air and the annual gas inspection along with it. The question is whether the electrical service has capacity for the load. Send us the existing gas heater's BTU rating and your available service and we will tell you what it takes.

Can I get a price on a full job's worth?
Yes. Multi-unit and contractor pricing is available on Ouellet heating - send the schedule or the count and we will quote it. Most heating orders over a handful of units are priced by our counter team rather than at list.
