What it costs to plug in a Ford F-250 / F-350 Super Duty — and what it saves
The catalogued element for the F-250 / F-350 Super Duty draws 400 W. Natural Resources Canada recommends a timer that runs the heater two hours before you drive rather than all night — that is what the numbers below assume.
| Province | ¢/kWh | Cost per 2 h plug-in | Full winter (120 nights) | Net per day |
|---|---|---|---|---|
| Quebec | 7.0 | $0.06 | $6.72 | +$0.53 |
| Manitoba | 10.2 | $0.08 | $9.79 | +$0.50 |
| Ontario (avg TOU) | 12.8 | $0.10 | $12.29 | +$0.48 |
| Alberta | 14.0 | $0.11 | $13.44 | +$0.47 |
| Saskatchewan | 15.5 | $0.12 | $14.88 | +$0.46 |
| Nova Scotia | 17.9 | $0.14 | $17.18 | +$0.44 |
Natural Resources Canada rates the Ford F-250 / F-350 Super Duty at 18.8 L/100 km in city driving (median across 1995–1999 model years). On a 20 km winter commute that is about 3.8 L a day. NRCan measured that at −20 °C a block heater improves overall fuel economy by as much as 10% — roughly 0.38 L, or $0.58 of gasoline at $1.55/L. On a single short trip at −25 °C the saving can reach 25%. In most provinces the electricity costs less than the fuel it saves; in the priciest it roughly breaks even, and you still get the wear, defrost and cabin-heat benefits.

Canadian buyer checklist
Three checks before spending money
1. Check for a cord
Factory cord exits low near the front bumper, driver's side.
2. Match the engine
Confirm displacement, fuel and model year against the table. OEM accessory numbers can vary by VIN and market.
3. Check recalls
Search the VIN in the Transport Canada database before using an unfamiliar factory heater or cord.
No exact-fit listing? Use the three-question heater selector for a safe fallback.
Where to look for the Ford F-250 / F-350 Super Duty block heater cord
Factory cord exits low near the front bumper, driver's side. Use a flashlight from above and through the lower grille, then check behind the bumper cover without pulling on an unidentified wire. A factory cord may be capped and clipped or zip-tied out of sight.
Found damage? Use the cord identifier before choosing between a plug-end repair and a complete cordset.
No tools? The stick-on option
If you'd rather skip the install entirely, a magnetic heater grips any flat steel surface — oil pan, block, transmission pan — and moves between vehicles. Check that the F-250 / F-350 Super Duty's oil pan is steel first: a magnet won't hold on aluminum or composite pans.

First: check whether you already have one
Canadian-market vehicles are often fitted at the port or dealer and then forgotten by the next owner, so check the cord location above before you buy anything. If a cord is there, test it — a dead element and a dead cord look identical from the outside.
If you need one installed
Budget $120–$400 CAD for the part plus about an hour of labour, and book in October — Prairie shop calendars fill after the first cold snap.
