False Facts About Diesel Generators
Diesel generators are used to power a wide range of appliances and equipment. They can be found in homes, commercial buildings, construction sites and more. However, there are still many false facts about diesel generators that people assume to be true. If you’re looking for the truth or need some advice on this topic, then keep reading! We’ll look at five common myths and explain why they aren’t true below.
They are Large and Bulky
If you are looking for a generator but are worried about how much space it will take up, you need not worry. Modern generators are surprisingly compact, and thanks to their self contained design, they do not have multiple parts spread across your site. Additionally, your generator needs only be as large as you need. We can provide a generator to suit your power requirements and space restriction to ensure you are not wasting space or money. We offer a wide range of generators and have the knowledge and experience to ensure you get the generator to suit your needs.
They are Very Loud
Gone are the days of requiring ear protection to operate a generator. Almost all modern generators are remarkably quiet thanks to improvements to their design. Additionally, if you have concerns, you can local your generator away from your buildings to help eliminate any noise at all.
They are Bad for the Planet
It is a common misconception that generators are terrible for the environment. It is correct that all generators will use some form of fossil fuel, be that diesel or natural gas. However, the equipment used has been developed over many years and is not as economical and efficient as possible. Thanks to this, you can use your generator without feeling guilty.
They are not Very Powerful
Ensuring you have sufficient power from your generator is essential. With the increasing amount of electricity being used in homes and businesses, the demand for high power generators has never been higher. Thankful generators have increased in power output to match the needs of customers. It is possible to run entire high power usage building on generator power alone, including hospitals and hotels.
They are not Needed in a Residential Property
The design of generators has been refined over the years, meaning you can now purchase compact and discreet generators that can easily add a generator to a residential home. This can allow for backup power during emergencies or blackouts. Thanks to the portability of some models, you can even take the generator with you to outdoor events or a camping holiday.
Generators can Operate without Regular Maintenance
Generators are like any other piece of equipment and require regular maintenance. Mainly people believe you can simply install a generator and leave it until it is needed; however, you must arrange regular maintenance and servicing to ensure your generator works as required. Here at Bellwood Rewinds, we are proud to offer expert generator maintenance and service for all customers.
All Generator Brands are the Same
The band of your generator may be something you are included to overlook. However, just in time with cars or electronics, the manufacture of your generator can significantly impact the reliability and lifespan of your generator. By investing in a high-quality generator from day one, you will avoid the stress and cost of any issues down the line. Additionally, some more prominent brands such as Pramac, JCB or Stephill Generators have offered fantastic customer service for years following the purchase of a generator. If you have any questions regarding the different brands of generators, contact our fantastic team here at Bellwood Rewind.
Diesel Generators are Too Expensive to Run
Many people assume that diesel generators are extremely costly to operate, but that’s not always the case. In fact, diesel is one of the most fuel-efficient options for long-term power generation, especially compared to petrol. Diesel engines consume less fuel over time, and because of their durability, they require fewer repairs and replacements. With modern fuel management systems and improved engine design, operational costs are lower than many expect. Plus, when used as a backup power solution during outages or emergencies, the cost of running a generator is far outweighed by the value of uninterrupted electricity. For businesses, the ability to maintain operations during power cuts can prevent major financial losses. At Bellwood Rewinds, we also offer a range of generators to suit various budgets and usage levels, so there’s no need to worry about being priced out of reliable backup power.
Diesel Generators are Only for Emergency Use
While diesel generators are excellent for emergency backup, they’re not limited to that role. Many industries use them for continuous or prime power supply, especially in remote areas or construction sites where a consistent grid connection isn’t available. They’re also used in agriculture, events, data centres, and even mobile food trucks. Diesel generators offer high torque and performance reliability, making them perfect for everyday applications as well as critical backup scenarios. Their flexibility is one of their biggest advantages—portable models can easily move between locations, and larger stationary units can support long-term operations. Whether you need a short-term power solution or a permanent off-grid power supply, diesel generators can meet the challenge. At Bellwood Rewinds, we help customers choose the right generator for their specific use case, not just for emergencies.
Used Generators Are Always Unreliable
It’s a common myth that used generators are too risky to invest in—but that couldn’t be further from the truth. At Bellwood Rewinds, we inspect, test, and refurbish all our used diesel generators before putting them up for sale, ensuring they meet performance standards and are ready for reliable use. In many cases, pre-owned generators come from light-duty applications or standby roles, meaning they’ve clocked very few hours. If properly serviced and maintained, a high-quality used generator can provide years of dependable power at a significantly reduced cost. This makes them a great option for businesses and individuals looking for backup power without breaking the bank. With regular servicing, a used generator can be just as trustworthy as a new model. As with any machinery, the key lies in condition, not just age—and that’s where our expertise in generator servicing makes all the difference.
Generators Can Be Left Idle for Months Without Issue
Another common falsehood is that diesel generators can be left unused for months and still operate flawlessly when needed. In reality, idle periods without regular testing or maintenance can cause issues like battery failure, fuel degradation, and clogged filters. Just like any engine-based equipment, generators need periodic running to stay healthy. Even standby generators, which are only used during power outages, should be exercised monthly and inspected regularly to prevent deterioration. At Bellwood Rewinds, we strongly recommend including your generator in a routine maintenance schedule, whether it’s in constant use or only on standby. We also offer generator servicing contracts to ensure your equipment is always in peak condition when you need it most. Regular inspections will help spot issues early and extend the generator’s lifespan significantly, saving you money and stress in the long run. Preventative care is far better than discovering a fault during an emergency.
All Generator Servicing Is the Same
Not all generator servicing is created equal, and believing otherwise can cost you in the long term. While some providers offer basic checks, a comprehensive service goes much further—testing fuel systems, load capacity, voltage regulation, and control panels. At Bellwood Rewinds, our servicing is tailored to the specific model, age, and usage of your diesel generator. We perform load testing, clean out systems, replace worn parts, and ensure everything is in working order to manufacturer specifications. Regular servicing from an experienced team doesn’t just prevent unexpected breakdowns—it also maintains efficiency, reduces emissions, and prolongs the life of your generator. Whether you rely on your generator daily or only during power cuts, consistent high-quality maintenance is essential. With over two decades of experience across petrol, diesel, and PTO generators, we understand the nuances between brands and models, ensuring nothing is overlooked in your generator’s care.
