Industrial Electric Steam Boiler Product Features:
- The industrial electric boiler does not require annual inspection, eliminating the complex registration and approval procedures.
- The microcomputer controller ensures rapid water heating and high efficiency. All operations can be easily performed via buttons or a remote control, saving time and effort.
- The heating groups are controlled by a step-by-step time-sharing method. Our industrial electric boiler can randomly activate or deactivate on load changes by the electric tube groups, which reduces the impact on the power grid. You can activate or deactivate heating stages manually to adjust boiler power output.
- You can choose the steam outlet pressure between 0 and 0.7 MPa. The accurate temperature evaporator automatically supplies heat to various applications at a set time.
- This equipment is self-contained. Upon arrival at the customer’s site, only the power supply, water inlet, sewage pipe, and steam pipe need to be connected, saving installation costs and time.
√ Boiler Operating Conditions Overview, Taking a 108kW Steam Boiler As An Example
This product operates stably under 10%-100% load conditions. At 100% rated load, the boiler’s operating parameters are: feedwater temperature 20°C, pressure 0.7 Pa, generating one ton of steam at 170°C in 6.7 hours. Using electricity as the energy source, the calculated thermal efficiency is 98%, and the total power consumption of the boiler is 109.5kW.
√ Product Structure Overview (108 kW As Example)
The boiler body is welded together from 273 seamless pipes, φ273×7 upper and lower headers, and four DN100 electric heating tube sockets.
This boiler heater utilizes direct heating tubes, featuring:
The heating tubes are in direct contact with the water, increasing the heat transfer area, improving thermal performance, and ensuring maximum output.
The heating tubes offer enhanced mechanical properties, a compact structure, and a small size. Maintenance, replacement, and installation are extremely convenient.
The heating tubes are made of stainless steel, ensuring safety, reliability, and a long service life.
Because the boiler utilizes electric heating, heat loss occurs only on the boiler surface, resulting in a thermal efficiency exceeding 98%, achieving zero pollution.
Heating is uniform and stable, and the evaporation area is large.
In addition to conventional pressure control, the boiler is equipped with advanced program controls such as automatic water quality testing, automatic interlocking, and automatic alarms for fully automatic control. Staged heater start and stop mitigate the impact on the power grid.
Automatic protection features include overheating, overvoltage, water shortage, short circuit, phase loss, and leakage protection, ensuring safety, reliability, and ease of operation. This boiler is equipped with a sensor-type plate-type water level alarm that automatically controls water supply, provides water level alarms, and performs interlocking functions.
When the water level falls below the low water level control point, the feedwater pump automatically starts to supply water to the boiler. When the water level falls below the minimum water level control point, an audible and visual alarm automatically sounds, shuts off the heating element, and requires manual reset.
When the water level rises above the maximum water level control point, an audible and visual alarm automatically sounds, shuts off the heating element, and requires manual reset.

Industrial Electric Steam Boiler Maintenance Suggestions:
During the winter months, when temperatures drop sharply, if the water pumps and valves of the boiler system are not properly protected against freezing, the accumulated water inside can freeze and expand, easily leading to rupture.
The following are conventional preventive measures; please choose according to your actual situation:
I. If the Industrial Electric Steam Boiler not in use for a short or long period:
✅️ Drain the accumulated water. Completely drain the system to prevent water in the boiler from freezing and rupturing pipes during winter.
✅️ Close the main valve and power supply. After cutting off the power, disconnect from the municipal water supply or other water sources. Close the main valve.
✅️ Drain the water in an orderly manner. First, open the drain valve or drain cock at the lowest point of the system, and simultaneously open the vent valve at the highest point of the system, allowing the water to drain naturally using gravity. Note that the boiler water must be completely cooled before draining to prevent burns.
✅️ Drain the water from the water pump. Unscrew the drain plug or several plugs at the bottom of the water pump to completely drain the water from the pump. For complex systems, consider using compressed air to assist in blowing out residual water in low-lying areas of the pipes and inside the valves.
✅️ Drain the valves. Close the shut-off valves, balancing valves, and actuators, and check for any other drain or vent ports.
✅️ Anti-freeze maintenance. After draining, keep all water valves and vent valves open.
II. If Industrial Electric Steam Boiler is a standby or intermittently used hot water boiler system:
Maintain the temperature or use antifreeze.
✅️ Maintain ambient temperature
Ensure that the boiler room and equipment room doors and windows are tightly closed, and that no cold air blows directly on the equipment.
If the ambient temperature is likely to remain below freezing, auxiliary heating equipment such as heaters or electric heaters should be used to maintain the indoor temperature above 5℃.
✅️ Electric trace heating
For pipes, water pumps, and valves exposed outdoors or in uninsulated spaces, self-regulating electric trace heating cables can be installed and wrapped with insulation cotton.
✅️ Use antifreeze
For closed-loop systems that cannot be drained but require antifreeze (such as some heating systems), a special boiler antifreeze (ethylene glycol or propylene glycol-based) can be added to the system.
Note: The appropriate concentration and type must be determined based on the local minimum temperature and system requirements, and ensure that the antifreeze is compatible with the system materials (such as seals). The use of automotive antifreeze is strictly prohibited. Consult a professional for advice.
✅️ Maintain circulation (for equipment with automatic control systems)
Set the thermostat to a lower temperature (e.g., 5-10℃) so that the system automatically starts circulating intermittently at low temperatures to prevent stagnant water from freezing.
III. Other Anti-freezing Auxiliary Measures and Inspections
✅️ Strengthen insulation: Check that the insulation layers of all water pipes, valves, and pumps are intact, especially the outdoor parts. Repair or thicken any damaged areas promptly.
Focus on protection at night: Night and early morning are the periods with the lowest temperatures and the highest risk of freezing damage; extra attention is needed.
✅️ Regular inspections: During low-temperature periods, regularly check the equipment status and manually touch the pipes to feel for abnormal temperatures.
IV. Anti-freezing Emergency Treatment Suggestions
If you find that pipes or equipment have frozen:
Do not directly use open flames or boiling water. Drastic temperature changes and uneven heating can easily lead to cracking.
Use a hairdryer or hot towels to slowly raise the temperature, or use a fan heater to slowly blow warm air from the end furthest from the freezing point to melt the ice.
During the ice melting process, gently open the valves or connections to allow the melted water to flow out slowly and release pressure.
