Commercial Electric Heating Boiler
The 72–90kW Commercial Electric Heating Boiler is designed for commercial and building heating systems that require a high-capacity electric heat source. Available in 72kW and 90kW models, it provides a practical solution for centralized hydronic heating applications.
Using electricity as the heating source, the boiler can be integrated with water-based heating systems and different types of indoor heat emitters according to project requirements.
High-Capacity Electric Heating
With 72kW and 90kW power options, this commercial electric boiler is suitable for projects with higher heating loads than typical residential electric heating equipment.
The two capacity options allow HVAC contractors and system integrators to select the appropriate output according to the building's heating demand and system design.
Designed for Hydronic Heating Systems
The electric boiler heats water for circulation through the building's heating network. It can be incorporated into different hydronic heating configurations, depending on the project design.
Typical heating terminals include:
This makes the boiler suitable for centralized heating applications in commercial and larger residential buildings.
Suitable for Commercial Heating Projects
The 72kW and 90kW electric boilers can be considered for a variety of building heating applications, including:
