Working principle
The electric pressurized hot water boiler is a "direct heating" pressurized equipment
1.Electrothermal conversion: After connecting to a high-voltage power source, the current passes through an electric heating tube immersed in water or directly through a body of water, converting electrical energy directly into thermal energy.
2.Pressure cycle: The heated water experiences an increase in pressure within a sealed boiler cylinder. The system circulation pump forcibly delivers high-temperature and high-pressure hot water from the boiler to the heating or process end, and the cooled return water is pumped back to the boiler for reheating, forming a closed pressure circulation system.
3.Automatic control: By using temperature and pressure sensors and a PLC controller, the start stop or power of the heating group is automatically adjusted to maintain a stable outlet temperature and system pressure.

Reasons and advantages of "pressure bearing" design
- Reason 1: Adapt to modern closed heating/process systems
- Reason 2: Improve effluent temperature and efficiency
- Reason 3: Compact structure reduces oxygen corrosion
Selling points and market positioning
- The operation process has no combustion, no smoke, no nitrogen oxides, and no carbon dioxide emissions, making it a "zero pollution" heat source.
- The conversion efficiency from electrical energy to thermal energy is nearly 99%, far exceeding any fuel boiler. Fast startup and responsive.
- No flame, no fuel storage and leakage risk. The equipment body complies with pressure vessel specifications and has complete safety protection.
- The operating noise is extremely low, with only the sound of the fan or water pump, which is superior to all combustion boilers.
- No need for complex auxiliary systems such as chimneys, fuel storage tanks, and oil pump rooms, simple installation, and small footprint.
