When it comes to generators, two of the most popular types are gas and diesel ones. Whether you’re considering one for a residential or commercial application, both offer distinct advantages and disadvantages that must be considered before selecting. To help make your decision easier, we have outlined the key differences between these two generator types here below.
Advantages of Gas Generators
Gas generators are the more cost-effective option when compared to diesel models. They tend to be lighter in weight than their diesel counterparts, so they can easily be moved from place to place and used in portable and stationary applications. Moreover, gas engines typically start up faster since there is no need for manual priming like what is required with diesel versions.
Disadvantages of Gas Generators
On the flip side, gas generators tend to produce fewer kilowatts per hour than their diesel equivalents due to combustion issues related to gasoline fuel sources. This could result in an inadequate power output if you require more energy from your generator than a single gas unit can provide. Furthermore, there may also be additional maintenance costs associated with operating a gas generator because its components need frequent replacement due to their susceptibility to wear and tear over time.
Advantages of Diesel Generators
Diesel generators may be slightly more expensive, but they tend to last longer than petrol generators – often up to five times longer, depending on usage conditions. In addition, as they require less regular maintenance (mainly due to their robust construction), running costs are usually lower in the long run, despite the higher initial price tag compared to petrol units. In addition, modern diesel engines produce more electricity than traditional petrol models, making them ideal for powering large appliances or multiple electronic devices simultaneously without interruption or loss of power quality over extended periods of use.
Disadvantages of diesel generators
On the downside, these machines take longer to start – requiring manual priming before each cycle – and are heavier and not designed for portability, with some models weighing in at several hundred pounds! They can also be expensive to service, especially if major engine parts such as injectors or pistons need replacing, whereas this task is relatively straightforward (and cheaper) on smaller petrol generators.
The bottom line
When it comes to choosing between petrol and diesel generators – whether for domestic or commercial use – there are certain pros and cons that should be considered before making a purchase decision. However, whatever your budget or whichever solution best suits your individual requirements, both fuel sources offer efficient levels of power generation alongside varying levels of convenience – it’s just a question of how much money you’re prepared to invest upfront versus the ongoing running costs further down the line.
