Essential Guidelines for Installing Immersion Heaters with Eddi+
Installing immersion heaters with the eddi+ system requires careful attention to specific technical details to ensure efficient and safe operation. Here are the key points to keep in mind:
Immersion Heater Specifications
- Power Requirements: Immersion heaters must be either 9kW three-phase or 3kW single-phase units.
- Three-Phase 9kW Heaters: These are wired in a star configuration, requiring a phase connection for each phase, a neutral, and an earth. Proper earthing of all heaters is mandatory.
Wiring and Safety
- 4-Pole Contactor: All heaters should be wired via a 4-pole contactor, which is supplied separately. This contactor works with the cylinder thermostat and thermal cut-out to manage the heater’s operation.
- Thermal Cut-Out and Thermostat: Heaters generally come with a thermal cut-out and control thermostat. If not, these components are required to ensure the heaters operate safely.
- Cable Specifications: Supply cables must be adequately rated for the heater load. They should also be heat-resistant and comply with EN 50525-2-11 standards.
Schematic for 9kW Immersion Heater
When installing a 9kW immersion heater, refer to the schematic diagram that illustrates the star configuration and the proper wiring connections.
Ensuring compliance with these guidelines is crucial for the safe and efficient functioning of your immersion heater system.
Conclusion
Proper installation and wiring of immersion heaters with the Eddi+ system are vital for optimal performance and safety. By following these specifications and guidelines, you can ensure that your immersion heaters operate efficiently and reliably, contributing to a well-managed and energy-efficient heating solution.
