Investing in a waste oil heater is a smart move for businesses looking to reduce heating costs and make better use of used oil. But with so many options on the market, choosing the right system can feel overwhelming. To help you make an informed decision, we’ve compiled 10 essential questions to ask before you buy a waste oil heater.
1. What types of waste oil can the heater burn?
Not all heaters accept every type of used oil. Ask which oils the system can safely handle—engine oil, hydraulic oil, gear oil, and more—to ensure compatibility with your available fuel sources.

2. How much heating power do I need?
Heating requirements vary depending on your facility size, insulation, and climate. Make sure the system provides enough BTUs to keep your space comfortably warm without overworking the unit. Exploring the full range of waste oil heater models from EnergyLogic can help you match the right BTU output to your space and application
3. How large is the fuel tank, and how often will it need refilling?
Consider the heater’s tank size and how frequently you’ll need to add waste oil. A larger tank reduces downtime but may affect installation space. Reviewing the available waste oil tank options from EnergyLogic can help you choose a storage solution that balances capacity, footprint, and compliance for your facility.

If you are choosing a smaller heater like the EL 75H, it comes with an onboard, 10-gallon waste oil storage tank to stay compliant with safety regulations. However, you can purchase a larger storage tank if needed, it will just need to be installed to the proper specifications.
4. What are the installation requirements when you buy a waste oil heater?
Check whether the system needs specific clearances, venting, or electrical connections. Some models are compact and easy to install, while others require professional installation. For more information, reach out to your local dealer or contact the EnergyLogic team.
5. How efficient is the heater?
High efficiency means more heat from less fuel. Look for features like advanced burners and heat exchangers, which can reduce oil consumption and save you money.

6. What maintenance is required?
All heaters need some upkeep. Ask about cleaning intervals, parts replacements, and service accessibility to make sure maintenance fits your schedule and budget. To better understand what routine care can look like, review EnergyLogic’s Waste Oil Heater Fall Maintenance Checklist, which outlines key steps to keep your system running efficiently and reliably.
7. Is the heater compliant with local regulations?
Waste oil storage and heating are regulated at the state and federal level, and requirements can vary by region. Confirm that your chosen system meets all relevant environmental and safety standards, and take time to understand how regulations keep businesses informed and compliant.
8. Does it come with warranty and support?
Reliable customer support and a solid warranty are essential for long-term peace of mind. Ask about coverage for parts, labor, and technical assistance. EnergyLogic’s warranty is one of the best in the industry. Just make sure to buy replacement parts from an EnergyLogic dealer or online at EnergyLogic.com/shop.

9. Can it be integrated with existing heating systems?
Some waste oil heaters can complement or supplement your current heating setup. Ask if the system can work alongside other heaters for more efficient overall performance.
10. What are the long-term cost savings when you buy a waste oil heater?
Consider not just the upfront price, but also fuel savings, reduced disposal costs, and ongoing maintenance expenses. A high-quality waste oil heater can often pay for itself in just a few years.
