These terms get mixed up, so let’s clarify the basics for Toronto homeowners and businesses.
Heating Oil (Home Heating)
- Often referred to as No. 2 heating oil.
- Used in oil-fired furnaces and boilers.
- Formulated for clean, efficient burn in heating systems.
- Delivered to on-site tanks (basement or above-ground).
Furnace Oil
- In many contexts, furnace oil = heating oil (used interchangeably).
- Local suppliers may use either name for the same home-heating product.
Diesel
- Similar base fuel to No. 2, but additives and tax treatment differ.
- Clear diesel: for on-road vehicles.
- Dyed diesel: for off-road use (generators, construction equipment).
- Not for residential furnaces unless your supplier specifically provides a heating-grade product for that application.
Practical Takeaways
- For home heat, order heating/furnace oil from your supplier.
- For equipment and generators, discuss dyed diesel and storage needs.
- Using the wrong product can cause performance issues—or regulatory trouble for road use.
