  • The structure includes a unique patent heating element known for high heating efficiency.
  • They also feature double dry-heating protection, automatic anti-freezing functions, and fault auto-detection for safety and reliability.
  • The boilers are also equipped with touch keys and an LED display for easy control and monitoringDesigned for External System Integration: This boiler is engineered to be compatible with external components.
  • It relies on external systems for circulating water and managing pressure and expansion.

Usage:

  • JNOD’s open-vented boilers heat water that is then circulated via pipework to radiators or an underfloor heating system.
  • They are adaptable for use in various settings due to their efficient heating capabilities and are controlled remotely through WIFI, making them convenient for modern homes and businessesHeating and Hot Water Provision: It provides heating through radiators and hot water, similar to other open-vented systems, but with the flexibility to integrate with various existing setups.

Suitable Application Scenarios:

  • Ideal for Retrofitting in Older Buildings: This boiler is particularly suitable for older homes or buildings where existing heating infrastructure can be utilized.
  • Large Residences with Specific Requirements: Due to its adaptability, it is ideal for large residences that have space for external tanks and need a reliable, efficient heating solution.
  • Properties with Separate Expansion and Storage Systems: It’s well-suited for properties that already have separate expansion and cold water storage systems in place, allowing for a more customized heating setup.
