Electric Heaters For Steam Pressure Systems


Steam pressure systems are essential in the food and beverage industry, as well as any precision manufacturing process. They rely on heaters to achieve and maintain high enough temperature to sanitize components and remove dirt, grime and milling residue.

Each year, more companies are making the switch to electric heaters for their steam pressure systems. There are a variety of electric heater types to fit any specific need.

Heater Types for Steam Pressure Systems

The best heater for a steam pressure system depends on the purpose and the type of system itself. A closed tank system, for instance, has different options than an open tank system. Here’s a quick look at three of the electric heater types.

Flanged Immersion Heater

In a closed tank steam system, flanged immersion heaters are one of the most popular electric heater options. Flange heaters use a simple design, mounting a tubular heating element on a flange. This simplicity makes it reliable, as well as easy to run, maintain, and repair.

Electric flanged heaters are highly customizable and can meet precise temperature requirement.

Boiler Heaters

Boiler heaters are another good heater option for closed tank systems. An electric boiler heater is the most efficient option for heating steam. They are quiet and clean, making them ideal in laundry and kitchen services.

They are suitable for low-pressure or high-pressure steam pressure systems up to 1000 psig. Boiler flange designs are customized to the purpose, usually using either a square or rounded shape.

Over-The-Side Heaters

Over-The-Side heaters (OTS) are not as common as flange or boiler options. That’s because they’re built for open tank systems. Open tanks are less common for steam pressure, but when they are used, an OTS heater is often the best choice.

For example, an automotive parts manufacturer required an electric steam pressure heater. An OTS heater was the best choice for their specific use. The manufacturer not only has an open system, but uses multiple tanks. An over-the-side heater is easy to remove and install. This makes it possible to use them in multiple tanks, without having to purchase multiple heaters.

Benefits of Wattco Immersion Heaters for Steam Systems


The intelligent and custom design of Wattco immersion heaters makes them capable of achieving temperature efficiently. Each heater is selected and manufactured to meet the specific needs of the process. This maximizes efficiency.

As well, the use of electric power further improves efficiency. Electricity is able to achieve temperature faster and with less energy waste. This makes them less expensive to operate than fossil fuel heaters.

Easy & Low-Cost Repair/Maintenance

Wattco immersion heaters use a simple design. This makes maintenance easy and minimizes repair and maintenance costs. With fewer parts, they are easier to clean and there is less opportunity for failure.

If repair is necessary, the tubular heaters are replaceable. As a result, it only takes a few minutes of operational downtime to fix. This means lower repair costs, and minimizing profit loss from production stoppages.

Ideal for Workers

If people are working in close proximity to the steam pressure system an electric immersion heater is ideal. They offer a quieter operation as well as a safer environment. Electric heaters let are smoke-free, creating a healthy environment for employees.


Wattco manufactures and supplies accessories for heaters such as thermostats and digital controllers. As a result, they are more compatible when bought with a heater than buying parts piecemeal from different companies. As well, Wattco representatives are better able to recommend the best components and accessories for your heater.
