Efficient Boiler Installation: Replacing an Aging 150 KW CXI Boiler with the Ideal Evomax

Background

Our team recently undertook the replacement of an aging 150 KW CXI boiler, a unit that had provided reliable service over the years but was increasingly becoming difficult to maintain due to the unavailability of parts and extended delivery times. As winter approached, the risks of a potential breakdown became too great to ignore, necessitating an upgrade.

Challenges

1. Aging Equipment: The old CXI boiler had served beyond its prime. Although it had been a dependable workhorse, the lack of available parts and long wait times for replacements posed significant risks, particularly during peak demand periods.
2. System Integrity: The existing system was prone to issues related to dirt and debris, which could potentially damage a new boiler if not properly addressed.
3. Flueing Requirements: The new boiler required updated flueing to handle condensating flue gases, necessitating relocation of the boiler to meet these requirements.

Solution

Boiler Selection:

• We selected the Ideal Evomax boiler for its modern efficiency and reliability. This unit is well-suited for environments where operational reliability is critical, especially during the colder months.

System Preparation:

• To protect the new boiler, we installed a plate heat exchanger, which acts as a barrier between the old system and the new boiler. This prevents any residual contaminants from causing damage.
• A thorough cold flush of the system was performed to remove any existing debris, and a dirt separator was fitted to maintain the cleanliness of the system moving forward.

Boiler Relocation:

• Due to the new flueing requirements for handling condensating gases, we decided to relocate the boiler. This involved carefully planning the repositioning to align with the existing gas, flow, and return connections.
• The new flue system was installed to ensure compliance with current standards and to maximize the efficiency and safety of the installation.

Outcome

The new Ideal Evomax boiler was successfully installed and integrated into the existing system. The precautions we took—including the installation of the plate heat exchanger, cold flush, and dirt separator—helped ensure the longevity and efficiency of the new system.

By relocating the boiler and updating the flue system, we not only met regulatory requirements but also optimized the boiler’s performance. The result is a modern, efficient heating solution that is ready to handle the demands of the upcoming winter season.

Key Takeaways

• Proactive Maintenance: Regular evaluation of older systems is crucial to avoid unexpected breakdowns, especially during critical periods.
• System Compatibility: Ensuring compatibility between new and existing systems can prevent potential issues and extend the life of new equipment.
• Compliance: Adhering to updated standards, such as flueing requirements, is essential for both safety and efficiency.

This project highlights the importance of timely upgrades and thorough preparation when dealing with aging infrastructure.
