Whether it’s because you want to save more money on fuel, save more time by not having to change or fill up your generator as often, or you’re watching your impact on the world around you, finding the most efficient generator is an important goal.
That’s why we’ve taken the time to collect our most efficient generators in one place.
Benefits of an efficient dual fuel generator:
- No smells or storage issues: If you don’t need as much petrol lying around, you don’t need to worry about storing large quantities of petrol or the smells they omit.
- Low running costs: Bottled gas is about 30-50% cheaper than petrol, and the larger the cylinder of bottled gas you buy, the more savings you make. As fuel becomes more expensive, you want a generator that’s not reliant on petrol to run.
- Eco-friendly: Bottled gas has cleaner omissions that petrol, so you’re choosing a method of power that reduces your impact on the world around you.
