As temperatures drop, Industrial Heating Oil (IHO) plays a crucial role in keeping buildings warm, equipment operating, and business activities running smoothly. If your tank unexpectedly runs low, it can lead to disruption, downtime, and avoidable repair costs.
This guide explains what to do if you run out of IHO and how to prevent it happening again.
1. Confirm The Issue
If heating stops or equipment begins to fail, first confirm that the cause is a lack of fuel. Check tank levels, secure the area if necessary, and make sure there are no unrelated mechanical faults.
2. Contact Your Supplier
A quick response is important. As soon as you realise your tank is running low or empty, get in touch with your fuel supplier. Provide your location, the quantity of IHO required, and any relevant access instructions for the delivery.
At Oilfast, we understand how disruptive an unexpected fuel shortage can be. Our team will always do our best to arrange a delivery as quickly as possible to keep your operations running.
3. Prepare for Delivery
Before your delivery arrives, ensure there is clear access to your tank. This helps the driver complete the drop safely and efficiently without delays.
4. Understand the Risks of Running Too Low
Allowing your tank to run completely empty of industrial heating oil can cause more than operational disruption. Sediment that settles at the bottom of the tank may be drawn into your boiler or heating system, potentially leading to costly damage and the need for an engineer callout.
Maintaining healthy fuel levels protects your heating system and reduces the risk of downtime.
5. Consider Long-Term Prevention
Once the immediate issue has been resolved, it is worth reviewing options that help you avoid running low again. These may include:
- Automatic top-up services
- Remote tank telemetry systems with low-level alerts
- Scheduled monthly or quarterly deliveries based on usage patterns
These measures provide peace of mind and ensure your heating supply remains consistent throughout the year.
