What are Steam Heating Coils?

Steam heating coils are an efficient and popular way to generate heat and are used in many industrial applications. They operate by converting energy stored in a fuel source, such as natural gas or coal, into steam which is then used to heat up liquid passing through the coil. This heated liquid can then be used for different purposes, ranging from providing hot water for a building to powering manufacturing processes. In this article, we’ll take a look at how steam heating coils work, their advantages over other types of heating systems and some common applications where they are used. We’ll also explore some safety tips to keep in mind when using and maintaining steam heating coils.

What are steam heating coils?

Steam heating coils are devices that are used to transfer heat from a steam source to another medium, such as air or water. Steam heating coils typically consist of a series of metal tubes that are wound into a coil shape. The steam is passed through the coils and the heat is transferred to the surrounding medium.

Steam heating coils are commonly used in a variety of applications, such as space heating, domestic hot water heating, process heating, and drying. Steam heating coils are also sometimes used in vehicle engines to preheat the engine coolant before it enters the cylinders. This can improve engine efficiency and reduce emissions.

How do steam heating coils work?

Steam heating coils are a type of heating element that uses steam to heat a space. The steam is generated by a boiler and is piped to the heating coil. The coil is usually made of copper or stainless steel and is filled with water. As the steam passes through the coil, it heats the water and transfers heat to the surrounding air.

Steam heating coils are often used in industrial applications, such as factories and warehouses, because they can provide a large amount of heat quickly. However, they can also be used in residential settings. Steam heating coils are typically more expensive than other types of heating elements, such as electric resistance heaters, but they are more efficient and have a longer lifespan.

Benefits of steam heating coils

There are many benefits of steam heating coils, including the fact that they are very efficient and can save you money on your energy bills. Steam heating coils also have a long lifespan and require little maintenance, making them a great choice for many homeowners.

Types of steam heating coils

There are four primary types of steam heating coils: bare, finned, tube-in-tube, and Regenerative Air Heater (RAH).
Bare coils are the most basic type of steam heating coil and consist of simply a series of metal tubes through which steam can flow. Because there is no external surface area for the steam to transfer its heat to, bare coils are typically used in applications where there is an external heat source, such as a boiler or solar collector.
Finned coils have fins attached to the outside of the tubes. The fins increase the surface area of the coil, which allows for more efficient heat transfer from the steam to the surrounding air. Finned coils are often used in forced air systems, such as furnaces and humidifiers.
Tube-in-tube coils are similar to bare coils, but with one key difference: there is another set of tubes inside the first set of tubes. The space between the two sets of tubes is typically filled with a heat transfer fluid, such as water or glycol. This type of coil is more efficient than a bare coil because it allows for heat to be transferred from the steam to the fluid, which then transfers it to the surrounding air. Tube-in-tube coils are often used in radiant floor heating systems.
RAHs are a type of regenerative air heater that uses steam to heat incoming air before it enters a building. The incoming air passes through a series of

How to choose the right steam heating coil

There are a few factors to consider when choosing the right steam heating coil for your needs. The first is the intended use of the coil. For example, if you need a coil for occasional use, a less expensive model might suffice. If you plan to use the coil regularly, however, it’s worth investing in a higher quality model that will last longer and perform better.

The next factor to consider is the size of the coil. The size will determine how much heat it can generate and how quickly it can do so. If you need a large amount of heat quickly, then a larger coil is necessary. Conversely, if you only need a small amount of heat or can afford to wait longer for it, then a smaller coil will suffice.

Finally, consider the price when selecting a steam heating coil. Generally speaking, higher quality coils cost more but are worth the investment if you plan to use them frequently. Cheaper coils may be sufficient for occasional use but won’t stand up to regular wear and tear as well as more expensive models. When making your decision, balance your needs against your budget to choose the best possible option for you.


Steam heating coils are an efficient and cost-effective way to provide heat in a variety of different applications. They are reliable, effective, and easy to install and maintain. Steam heating coils provide consistent temperature control with minimal energy consumption. With the right setup, steam heating coils can be used for both residential and commercial use. If you’re looking for an efficient way to heat your space, steam heating coils may be the perfect solution for you!
