Open-vented Electric Boiler

  • JNOD open-vented boilers are designed to be compatible with external circulation pumps and water tanks, as they don’t have these components built-in.
  • This design results in a smaller product size.
  • There are different series available:
    • The BQ series (with power ranging from 5.5kW to 14.4kW);
    • The BK series (with power at 40kW and 52kW);
    • The BC series (with power at 5.5kW to 26kW)

Features:

  • JNOD’s open-vented electric boilers are wall-mounted and feature a compact design to save space.
  • With patented heating element to achieve high heating efficiency, is the first patented cast aluminum heating element technology.
  • It has double dry-burning protection, automatic anti-freeze function, and automatic fault detection function, make it safe and reliable.
  • Designed for External System Integration: This boiler is engineered to be compatible with external components.
  • Equipped with touch keys and an LED display for easy control and monitoring. 
  • 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.
