Slash Your Energy Bills by Up to 90%: The Hidden Goldmine of Storage Tank Insulation
In today’s economy where energy costs continue to soar, industrial facilities and businesses are desperately searching for ways to reduce their operational expenses. One of the most overlooked yet highly effective solutions lies right under their noses—or more accurately, around their storage tanks. Each year, large amounts of energy are wasted due to hot storage tanks not having proper insulation systems in place, creating a massive opportunity for cost savings that many organizations haven’t fully explored.
The Real Cost of Uninsulated Storage Tanks
An uninsulated tank can increase energy bills as electric storage tank heaters or cooling systems work harder to maintain the set temperature. The financial impact is more significant than most facility managers realize. Poorly insulated tanks reduce efficiency, add energy costs, accelerate equipment failures and condensation and increase safety risk within an industrial facility. Failure to maintain stored materials at the adequate temperature range can prevent them from being pumped or moved.
Consider this: the heat loss at tank walls and roof will fluctuate when the liquid level increases or decreases but the heat loss through the bottom will always remain constant. This can be explained by the fact that when the storage tank is only filled at 10 percent of its capacity, the tank bottom will always be in 100 percent contact with the hot liquid, making it the a very susceptible area for heat transfer and energy loss.
Quantifying the Energy Savings
The numbers tell a compelling story. Insulating the tank base can immediately reduce the heat loss through the bottom up to 90%. For businesses operating heated storage tanks, this translates to substantial energy cost reductions that compound over time.
Real-world examples demonstrate the potential savings. A business that spends $10,000 on insulation may save $5,000 per year in energy costs. In one detailed case study, a tank operating at 280°C showed yearly average heat loss of 263 W/m² for an uninsulated tank base versus only 70 W/m² for an insulated tank base, with energy savings of $0.13/ft².h.
Understanding Payback Periods
The payback period itself is the amount of time that it takes for an energy efficient measure’s, such as insulation’s, savings to break even with its original cost. With insulation for example, the “original cost” is the amount you invest on the material and its installation.
The calculation is straightforward: Divide the cost of insulation installation by the annual energy savings. This will give you an idea of how long it will take for the energy savings to cover the cost of the insulation.
Industry data shows remarkably short payback periods. Depending on storage temperature, insulation thickness and energy costs, the payback period for insulating the bottom of a storage tank bottom can be as low as just a few months and often within a few years. In the case study mentioned earlier, the payback period for continuous service was just 10.7 months.
Beyond Energy Savings: Additional Benefits
While energy cost reduction is the primary driver, a tank base insulation system has other benefits. First, the insulation system needs to protect the structural concrete base material against high temperatures. This means that the reinforced concrete foundation can be installed more cost efficiently.
A closed-cell foam industrial tank insulation helps protect the steel base structure of the tank against condensation, leading to expensive corrosion-related issues. This protection extends equipment life and reduces maintenance costs, adding to the overall return on investment.
Professional Installation Makes the Difference
The quality of installation significantly impacts the effectiveness of any insulation system. Companies like Vertarib, based in Jericho, NY, specialize in providing advanced tank insulation solutions for industrial applications. Vertarib Inc. specializes in providing high-quality tank insulation systems tailored for various industrial applications, ensuring enhanced efficiency across multiple sectors. With over 40 years of experience, their team of trained technicians designs, engineers, manufactures, and installs customized insulation solutions optimized for both newly constructed and retrofitted storage tanks. They serve a diverse clientele including industries such as energy, food and beverage, petrochemical, and water storage, delivering products that meet stringent standards and regulations.
For businesses considering storage tank insulation, working with experienced professionals ensures optimal system design and installation. Advanced vapor barriers and state-of-the-art panel designs can function in temperatures as low as -50° F, and companies design, build, and install insulation systems on newly-constructed tanks as well as retrofit existing tanks with high-efficiency tank insulation systems.
Cost Considerations
The average cost to insulate a storage tank is approximately $10 per square foot, though many factors will alter the development of that price. Factors affecting cost include tank size, existing insulation conditions, accessibility, product temperature requirements, and material specifications.
However, the investment in a tank base insulation system is very minimum compared to the cost of the energy saved. This results in rapid payback times often, depending on the temperature and size, merely months.
Making the Investment Decision
When evaluating whether to invest in storage tank insulation, consider both immediate and long-term benefits. A well designed and installed thermal tank base insulation system will result in energy savings, increased worker safety, longer tank life and a relatively short payback period.
Insulated tanks provide significant cost savings over time, and the insulation value of cellular glass insulation does not change during its lifespan, which helps to ensure constant and lasting energy savings. This allows for easy calculation of the yearly energy savings, payback periods, annual financial yields and, saved emissions over the lifetime of the tank.
Conclusion
Storage tank insulation represents one of the most cost-effective energy efficiency improvements available to industrial facilities. With payback periods often measured in months rather than years, and energy savings that can reach 90%, the question isn’t whether you can afford to insulate your storage tanks—it’s whether you can afford not to. As energy costs continue to rise and sustainability becomes increasingly important, storage tank insulation offers a proven path to significant, lasting savings that benefit both your bottom line and the environment.
