Ouellet ODSR04008BL-TAV Air Diffuser Ceiling Heater 4000W 208V, White

The Ouellet ODSR04008BL-TAV is an air diffuser ceiling heater rated 4000 W at 208 V, finished in white. It is a heater built into an air-diffuser body that drops into a suspended T-bar ceiling and reads as part of the ceiling grid rather than as equipment.

TL;DR

• Output: 4000 W at 208 V (13,660 BTU/h)
• Draw: about 19.2 A - size the circuit at 125% per CEC 8-104
• Finish: White
• Control: built-in thermostat, adjustable air vane
• Availability: in stock in Vaughan, ON. Ships Canada-wide, counter pickup available

Quick Specs

Best For

• Suspended-ceiling commercial spaces - offices, clinics, retail
• Zones where the heat has to disappear into the ceiling plane
• Perimeter offices the central system underserves

Why Contractors Choose It

• Drops into a standard suspended ceiling grid and disappears
• Moves real air volume rather than relying on convection
• Built-in thermostat and adjustable air vane on TAV models
• Frees every wall and floor surface in the room
• Built for a 208 V supply - Ouellet encodes voltage in the part number, so there is no field conversion and no wrong-voltage guesswork

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:

• ODSR02000AM - 2000 / 1500 W, 240 / 208 V, almond

Installation Notes

CEC Section 62 applies. Units dropped into a suspended T-bar grid must be independently supported to structure, not carried by the grid alone. Size conductors at 125% per CEC 8-104.

Common Mistakes to Avoid

• Supporting the unit on the grid alone rather than independently to structure
• Blocking the diffuser face with signage or sprinkler escutcheons
• Ordering 240 V for a 208 V building

Frequently Asked Questions

Is the Ouellet ODSR04008BL-TAV 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 supply voltage does the ODSR04008BL-TAV need?
208 V. Ouellet encodes voltage in the part number, and this one is a 208 V unit - it is not field-convertible to another voltage. If your service is different, there is a matching part number in the same series for it.

What size breaker and wire does the ODSR04008BL-TAV need?
The unit draws about 19.2 A at 208 V. Fixed electric heat is a continuous load, so CEC 8-104 sizes the conductor and the breaker at 125% of that - about 24.0 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 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 ODSR04008BL-TAV need a separate wall thermostat?
No. This model ships with a built-in thermostat, adjustable air vane - 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.
