Tank Heating Coils Designed for Long-Lasting Efficiency

Tank heating coils are a key component of thermal fluid heating systems. These coils are used to heat and regulate the temperature of tanks filled with stored materials in dozens of industries, including asphalt, chemical, refinery, and more.

Because they play a crucial role in the heating and maintenance of large quantities of material, tank heating coils must be designed to be durable, reliable, and efficient.

Whether made with carbon steel or 316L stainless steel, we carefully design and build our tank coils to last for many years. We realize how difficult it is to get into a tank filled with fluid to repair or replace a tank heating coil and, therefore, take extra care with this important piece of equipment.

Many years of design and practical operating experience go into the process and mechanical design of every tank heating coil. With the use of seamless pipe and solid helically wound fins, our tank coils are built for peak performance and designed to last for decades.

Custom Tank Heating Coil Solutions to Meet Your Facility’s Needs

American Heating Company can utilize either steam or thermal fluid as the heating medium of our tank heating coils. The fluid to be heated can vary greatly from project to project and American Heating Company engineers can design tank heating coils for any of these projects, even when materials such as stainless steel must be utilized.

These coils can also be designed to fit into an existing tank manway or into any specialty tank, whether it is vertical or horizontal. If you have a need, our team of engineers can work with you to design a coil that meets your requirements – and exceeds your expectations!

Helically Wound Tank Coils Versus Longitudinal Tank Coils

While there are many ways a tank coil can be built, experience has proven that in most scenarios tank coils with helically wound fins are the best way to go. Longitudinal fins are an alternative option, but they tend to fall short of their helical coil counterparts in a number of ways. side by side comparison of helical vs. longitudinal tank heating coils

Helical tank coil benefits include:

Better Heat Transfer

Experience has shown that the horizontally installed helically wound fin tubes have two times better heat transfer than a longitudinal horizontally installed solution.

Reduced Cost

Helically wound coils require only half as many coils as longitudinal coils thereby saving significant capital and installation cost. 

Reduced Coking

A helically wound fin design removes the ‘dead spots’ that occur in a longitudinal fin. This makes helically wound coils much less likely to coke.

Helically Wound Tank Heating Coils Versus Bare Pipe Coils

A helically wound fin solution over a bare pipe solution has several advantages.

Increased Surface Area

With the helically wound coil, you have 10-12x greater surface area per foot of pipe so you need significantly less pipe to heat the tank.

Resolution of Other Tank Heating Problems

Most customers or engineering companies that use bare pipe simply put as much pipe in the bottom of the tank that they can fit, which can create other issues. With a helical coil, you can avoid these other tank heating issues.


Another significant advantage is that at AHC we do an exact thermal calculation based on your boiler or hot oil heater to create a specific solution. We’ll create a helical tank coil that’s customized to meet your needs.

Cost Savings

A coil system from AHC can save 50-75% in comparison to a bare pipe solution. You can learn more about how AHC heating coils can save 50-75% on project cost versus bare pipe here. (Note that the “Standard Heating Design” shown in the photo is an actual design from a large scale engineering firm. It is estimated to cost 75% more than the AHC solution.)

Other benefits of tank coils from American Heating Company include:
