DETTSON Suprême Avantage SUP15-A240V12 Electric Furnace | 15 kW - 240V

The comfort of an ECM motor in a 15 kW electric furnace

For homes already thinking about air conditioning

You heat with electricity through ductwork and you plan to add central air conditioning or a heat pump in the coming years. The Dettson Suprême Avantage SUP15-A240V12 was designed for that scenario. It heats with electric elements that switch on in sequence, then hands air distribution to a 1/2 HP ECM motor whose airflow is set separately for heating and for cooling.

In practice, the day a coil is added on the supply or return side, up to 3 tons, the airflow can be adjusted for cooling mode instead of staying locked on the winter setting.

What the Dettson sheet states

The furnace delivers 15 kW at 240 V and 11.3 kW at 208 V, with a first stage of 10 kW at 240 V. The front panel groups the continuous-fan switch, the low/high power switch, the heat-demand indicator light and the breakers. Dettson publishes a 54 °F temperature rise at 240 V and covers parts for 5 years in residential use, as well as the ECM motor for 5 years. Labour is not covered by the manufacturer.

In a Quebec home

Whether you live in a bungalow in Laval, a cottage on the South Shore or a plex in Montreal, the location is easy to sort out: the Suprême installs upflow, downflow with the DFB-SUP base depending on the floor, horizontal to the left or right, or suspended. It is 36 1/2 in high and 22 in deep, and it is approved for zero clearance and for copper or aluminum wiring.

On the electrical side, Dettson calls for an 80 A maximum breaker at 240 V (70 A at 208 V). The manual does not publish the ampacity for this size: our team confirms it before wiring. The standard connection uses two wires; three wires are possible with accessories.

With a heat pump, the elements become the backup heat, but Dettson requires that they never heat at the same time as the heat pump. The thermostat we install takes this rule into account.
