The world of industrial Boilers is full of different options. Each Boiler has its specifications, strengths, and weaknesses. Some are more efficient than others, while others are cheaper. In the ocean of boilers, one name is the industrial hot water boiler. It is known for its unparalleled efficiency and some similarities with steam boilers. 

Don’t have any idea how to choose the right hot water boiler for your industry? No need to worry, as this guide will tell you the working principle, types, benefits, and standout points of an Oil Hot water boiler system. This way, you can decide whether it is the right option for your factory. Let’s get started!

How to Identify Oil Hot Water Boiler?

Hot water boilers are common among small industrial uses. They are used for small-scale applications. And that’s where an oil hot water boiler comes in. It is significantly larger in size and is used for large-scale projects. 

You will also notice oil-fired burners in most oil hot water boiler. They are present on the front part of the boiler. This simple design feature makes these boilers comparatively easier to operate.

Another unique design aspect of the boiler is its pressure vessel. In many systems, it is vertical. However, the hot water boilers vessel is horizontal. It is present in a cylindrical tube shape, closed by insulators. 

But even with its large size, these boilers are pretty compact. That’s mainly because of the system’s space-efficient design. It can easily be installed in an industrial space without occupying a large area. 

Working Principle of Oil Hot Water Boiler System

An oil hot water boiler is somewhat similar to a coal fired steam boiler in its operation. That is why most people confuse the two systems. They both require to be filled with water to operate. However, a steam boiler works with a fixed water level and steam. On the other hand, the hot water boiler industrial fires its burner and tubes to heat the water.

This system stores water in its boiler shell that contains circulating pipes and tubes. The heated water makes its way to the boiler for reheating. Oil hot water systems have wisely crafted pipework. It allows the water to move freely without loss.

Note that the number of water passes can vary from system to system. Generally, most boilers have two or three passes for the heated water. Moreover, these boilers have a single chamber that repeatedly combusts the gases. It ensures total combustion, thanks to its efficient burner. 

Types of Oil Hot Water Boiler

An oil hot water boiler is categorized into three main types. This classification is primarily based on temperature capacity. However, that can also create differences in its applications. That said, let’s look at the types one by one for a better understanding.

1. Low Temperature Boilers

Low temperature hot water boilers are commonly abbreviated as LTHW. These systems support temperatures below 250F (121°C). Along with a lower temperature, these boilers can only work with a maximum pressure of 30 PSIG.

As you may expect, these industrial boilers are not ideal for large-scale industries. Instead, they are common in small-scale productions or domestic purposes. Their primary goal is to provide hot water in a limited capacity during winter months. 

2. Medium Temperature Boilers

A medium temperature hot water boiler works ideally for medium-range temperatures. Commonly referred to as MTHW, this system is widely present in smaller industries. But they are also applicable to medium-scale projects and productions.

Medium-range oil hot water boilers can produce a pressure of up to 150 PSIG. Their operating temperatures can be anywhere from 250F to 350F. 

3. High-Temperature Boilers

High-temperature oil hot water boilers are the most efficient and capable systems. They can operate at a maximum pressure of up to 290-300 PSIG. Plus, their max temperature can exceed 350F.

These boilers are ideal for heating purposes in large-scale industries. They can achieve what the other two types can not. That’s because of their high-temperature capability. Other than industries, these boilers are also used for heating larger areas, like a district. 

Oil hot water boilers are also categorized based on their pressure capabilities. You might have heard of low and high-pressure hot water boilers. Both of them are suitable for commercial and oil applications. 

Another common variation is the industrial electric hot water boiler. However, its operations and working principle differ drastically from an ordinary hot water boiler. It has a stainless steel body and electrical functions, which are helpful for commercial and small-scale industrial uses. 

3 Key Benefits Of Oil Hot Water Boiler

An oil hot water boiler is a capable heating solution. It has a wide range of commercial and industrial applications. The best part is that it offers high value for money, making it one of the most cost-effective systems. 

Let’s look at its main benefits in detail!

1. Superior Efficiency

One of the biggest benefits of an oil hot water boiler is its unmatched efficiency. The system can be up to 85% efficient under the right conditions. Average hot water boilers are around 70-75% in efficiency rate. 

Two reasons explain why this industrial system is so efficient. Firstly, it reheats the heated water by passing it through its durable pipelines. As a result, no water is lost in the process.

Secondly, the boiler combusts the gas multiple times in its chamber. It allows it to utilize the full combustion energy required for heating water. These two factors make the boiler one of the most efficient industrial options.

2. Inexpensive Installation & Maintenance

This industrial boiler is one of the easiest systems to install. That is why many industrialists prefer it for large-scale applications. The oil hot water boiler price is pretty reasonable, considering its efficiency. It returns a high value on money, thanks to its effective operation.

Another thing is its easy maintenance, requiring no professional assistance. Not only is it straightforward, but also relatively cheaper than most other boilers. That’s why this boiler gets a plus point in accessibility. 

3. Simple Operations

The industrial boiler has a straightforward working mechanism. It is understandable, even for inexperienced individuals. At the same time, its operation is pretty effective. Combine that with low-pressure settings and capable temperatures, and you have one of the best boilers. 

But that’s not even the best part. This oil hot water boiler eliminates the operating costs involved in other systems, like a steam boiler. It doesn’t have steam leaks, traps, or blowdowns to compromise its operations. 

Differences between Oil Hot Water Boiler and Steam Boiler

While steam boilers and oil hot water boilers have similarities, they have many differences. The most obvious factor is the appearance. Steam boilers are comparatively larger and less space-efficient than industrial hot water boilers. Also, the installation methods for both systems can vary drastically.

That said, there are many other differentiating factors. Let’s go through them one by one.

1. Maintenance

Let’s talk about maintenance first, as it is a concerning aspect for industry owners and workers. Regular maintenance can be tiresome, and that’s the case with wood fired boilers. These systems operate at comparatively higher temperatures and pressures. That is why they need frequent care. 

Alternatively, oil hot water systems don’t require frequent monitoring and maintenance. However, they may still need protection against corrosion. But their temperatures and pressures are comparatively safer.

2. Heating Framework

Like a common industrial boiler, an oil hot water boiler uses a burner and heat exchanger to increase the water temperature. It also has a single chamber for gas combustion. 

In contrast, a steam boiler evaporates the water to produce heat. It doesn’t recirculate the water after heating, like an oil hot water system. 

3. Efficiency Rate

While both systems are efficient, it’s a matter of consistency. A steam boiler is resistant to colder temperatures, leading to energy waste. That’s why this system is comparatively less efficient. 

On the other hand, an oil hot water heating system is more consistent in its efficiency. It recirculates the water through its sturdy pipework to minimize energy waste and resistance. 

4. Applications

As the name suggests, oil hot water boilers have industrial applications. They are used commercially for bigger buildings. Although it has many times, most are dedicated to large-scale uses.

But that’s not always the case with steam boilers. These systems are used for comparatively smaller buildings and low to medium-end projects. That is why you might not see them often in larger industries.

Conclusion

An oil hot water boiler is one of the most efficient options in its category. This system has a high ROI (return on investment) thanks to its cost-effectiveness and higher energy efficiency. Combine that with its ease of installation, use, and maintenance, and you have an excellent option right here.
