As temperatures drop, staying warm in large, open or industrial spaces becomes essential. Two of the most common portable heating solutions are Diesel and LPG (Liquefied Petroleum Gas) space heaters. But how do they compare, and which is better for your space?
Let’s break it down so you can make an informed decision.
What Are Diesel Space Heaters?
Diesel space heaters use combustion to generate heat, typically via a fan-forced system. They burn diesel fuel to heat air, which is then distributed throughout a space. These heaters are well-suited for:
- Well-ventilated workshops
- Construction sites
- Open warehouses
- Outdoor or semi-enclosed areas
Pros:
- Great for heating larger or drafty spaces
- Lower fuel cost in some areas
- Powerful heat output
Cons:
- Requires ventilation due to exhaust
- Produces odour and emissions
- Not ideal for enclosed or poorly ventilated rooms
What Are LPG Space Heaters?
LPG space heaters use propane or butane gas as fuel. They come in both radiant and convection models, offering versatility depending on your needs.
Ideal for:
- Ventilated indoor spaces
- Portable site heating
- Workshops and garages
Pros:
- Clean burning when well-ventilated
- Portable and efficient
- Instant heat
Cons:
- Requires LPG cylinders
- Like diesel, ventilation is a must
- Slightly more expensive fuel than diesel in some areas
Key Differences at a Glance
| Feature | Diesel Heater | LPG Heater |
|---|---|---|
| Fuel Type | Diesel | LPG (Propane/Butane) |
| Best for | Large ventilated spaces | Medium ventilated indoor spaces |
| Heat Output | High | Medium to High |
| Ventilation Needed | Yes | Yes |
| Emissions | Moderate (fumes, odour) | Lower (cleaner burn) |
| Running Cost | Typically lower fuel cost | May be higher per cylinder |
Which One is Right for You?
-
Choose Diesel if you’re heating a large, drafty or outdoor space and need maximum output with more affordable fuel.
-
Choose LPG if you want something more portable, cleaner burning, and suited for semi-enclosed or indoor areas with proper airflow.
And remember — ventilation is crucial for both fuel types to avoid carbon monoxide buildup and ensure safe operation.
