Challenges and Solutions

The project involved installing the combi boiler in a home undergoing construction, with open valves for connections to additional equipment and piping. Our technician, Ed, ensured the system was properly integrated with the home’s plumbing and heating infrastructure while preparing for future additions as the renovation progressed.

Installation Process

1. Initial Assessment: We evaluated the homeowner’s heating and hot water requirements, selecting the ECO Tec 150 for its capacity to meet both demands efficiently.
2. System Placement: The unit was installed as a wall-mounted configuration to optimize space utilization, ideal for modern and retrofit applications.
3. Integration: The ECO Tec boiler was connected to the home’s heating system and domestic hot water lines, with open valves reserved for further construction work upstairs.
4. Calibration and Setup: Using the Unity 2.0 touchscreen controller, we configured the system for optimal performance and easy homeowner control. The step-by-step installation wizard and large display simplified the process.
5. Testing: Extensive testing was performed to ensure optimal performance and seamless switching between space heating and domestic hot water supply.

Results and Benefits

• Improved Home Comfort: The new combi boiler ensures consistent heat distribution throughout the home while providing an abundant hot water supply.
• Energy Efficiency: The 95% AFUE rating and ENERGY STAR® Most Efficient recognition translate to considerable energy and cost savings for the homeowner.
• Ease of Use: With the Unity 2.0 touchscreen controller, the homeowner enjoys intuitive control over their heating and hot water, as well as automatic maintenance reminders for optimal system performance.
• Future-Ready: Open valves were left prepared for additional connections as construction continues upstairs, demonstrating our flexibility and forward-thinking approach to complex projects.
