| High Light | Vertical Electric Hot Water Boiler ,Multifunction Electric Hot Water Boiler ,Electric Hot Water Boiler 90KW | ||
The High Efficiency Vertical Electric Boiler is designed to provide reliable heat for residential and commercial water-based heating systems. It uses fully immersed electric heating elements to transfer electrical energy directly into water, achieving an electric-to-heat conversion efficiency of over 99%.
The multifunctional design allows the boiler to support indoor heating directly or work with an external storage tank for domestic hot water applications.
The boiler uses Incoloy 800 heating elements as its core heating components. The elements are immersed in water, allowing generated heat to be transferred directly to the water circuit.
The heating elements are designed for high-temperature operation and long-term use, providing a stable heat source for daily heating requirements.
Incoloy 800 heating elements
Over 99% electric-to-heat conversion efficiency
Direct heat transfer through water
Stable heating performance
Suitable for continuous heating applications
A dedicated microcomputer controller works with temperature sensors to monitor changes in water temperature during operation.
The system automatically regulates the heating process according to the preset temperature, reducing the need for frequent manual adjustments.
This control method helps maintain a more consistent water temperature and provides a convenient operating experience for users.
The boiler adopts a modular heating structure, with individual heating modules operating independently.
This configuration allows the heating system to adjust its heat output according to operating requirements while providing greater flexibility during maintenance.
If one module requires servicing, the modular configuration also makes it easier to identify and handle individual heating components.
Safety is an important part of electric water heating. The boiler incorporates multiple protection components to monitor temperature, water level, pressure, and electrical conditions.
The available protection functions include:
Over-temperature protection
Water shortage protection
Temperature and pressure protection
Leakage protection
Safety pressure protection
Automatic heating control
These mechanisms work together to help maintain safe and stable boiler operation.
A multifunction LED display provides real-time information about the operating condition of the boiler.
Users can easily monitor the system status and adjust the required heating settings through the control interface.
The straightforward design makes the boiler suitable for both residential users and professional heating installers.
The vertical electric boiler can be integrated into a range of water-based heating systems.
It can provide heated water for:
Radiator systems
Underfloor heating
Hydronic heating circuits
Domestic hot water systems
Thermal storage systems
For projects requiring stored thermal energy, the boiler can be connected to an external insulated water tank. Heated water can then be stored and supplied according to the system's heating demand.
The multifunctional configuration provides flexibility for projects requiring both space heating and hot water.
For example, the boiler can supply a hydronic heating circuit while an external storage tank is used to provide domestic hot water.
This makes the system suitable for homes and buildings where one electric heating source needs to serve different thermal requirements.
The vertical design provides a practical equipment arrangement for heating rooms, utility spaces, and mechanical areas.
It is suitable for new heating installations as well as replacement projects where an electric boiler is required as the main or supplementary heat source.
The boiler can be used in:
Residential heating
Villas and apartments
Radiator heating projects
Underfloor heating systems
Commercial buildings
Domestic hot water systems
Thermal storage heating applications
Electric heating retrofit projects
Combining immersed Incoloy 800 heating elements, intelligent temperature control, modular heating technology, and multiple protection functions, this vertical electric boiler provides a practical heat source for modern hydronic systems.
It can be configured as a standalone electric heating solution or integrated with storage tanks and other water-based heating equipment, giving HVAC contractors, distributors, and system integrators greater flexibility when designing heating projects.
