A dual fuel generator is a versatile power unit that can operate on two different fuel types. Typically, dual fuel generators run on LPG (propane) or petrol. This provides flexibility and cost savings as users can easily switch between fuels depending on price availability. This flexibility makes dual fuel generators increasingly popular for:
- Backup power during outages – running essential appliances during power cuts
- Construction and maintenance work – powering tools and equipment
- Events and mobile applications – quiet, efficient power for temporary setups
- Off-grid and remote locations – flexible power where access to fuel is sparse
- Workshops and garages – dependable power for light machinery
Key Benefits
- Flexible Fuel Choice – run your generator on petrol or LPG, depending on what’s available. LPG is often easier to store long-term and can offer cleaner combustion.
- Lower Running Costs – LPG is often cheaper than petrol and burns more efficiently.
- Extended Run Time – using LPG allows you to connect a larger fuel cylinder for longer, uninterrupted power.
- Cleaner, More Efficient Operation – running generators using LPG, generally produces lower emissions and less carbon build-up.
- Reliable Backup Power – if one fuel source becomes unavailable, you can simply use the other – ideal for emergency or standby situations.
- Portable & Practical – dual fuel generators are often compact and portable, making them well-suited to domestic, leisure and professional use.
