4 of 6 ReviewsWe installed the NTI TRX085 after our old boiler started becoming unreliable, and we are extremely happy with the results. The biggest improvement has been the steady, even heat throughout our home. The boiler adjusts smoothly to our heating needs instead of constantly cycling on and off. It maintains a comfortable temperature without the temperature swings we experienced before. The system is also surprisingly quiet — most of the time, we do not even notice it running. I really appreciate the compact wall-hung design because it freed up valuable space in our utility area. The controls are easy to understand, and the Wi-Fi connectivity makes checking the system status much more convenient. Living in Canada, having a dependable heating system is essential, especially during the coldest months. After using the NTI TRX085 through winter conditions, we can confidently say it was the right choice for our home. Excellent performance, efficient operation, and great overall quality. Highly recommended.
Upgrading our old boiler to the NTI TRX085 was a major improvement for our home. Our previous system was outdated and noisy, and it struggled to maintain a comfortable temperature during colder days. Right from the first week, we could tell this was a much better solution for our home. The heating is much more consistent, and the system runs significantly quieter than our old unit. We especially like the wall-mounted design because it saved space in our mechanical room and gave the installation a much cleaner look. The 96% AFUE efficiency was one of the main reasons we selected this model. We wanted a reliable boiler that could provide dependable heat while using energy more efficiently. The stainless steel heat exchanger and advanced modulation technology give us confidence that this system is built for long-term performance. The built-in Wi-Fi feature is also very convenient. Being able to monitor the system and access controls easily adds another level of convenience that our previous boiler did not offer. Overall, this has been an excellent upgrade. The NTI TRX085 keeps our home comfortable, operates quietly, and feels like a high-quality modern heating solution.
Stable performance, fuel efficient and easy to operate via mobile app. Very satisfied with my choice.
Surprised at how quiet this boiler is. We even forgot we had heating – no noise at all. Highly recommended!
the perfect choice for my home! Stylish design, easy to install on the wall, and most importantly, reliable heat supply. With Wi-Fi control, it’s a godsend for the modern home. Recommended!
“I decided to share my impression of Boiler TRX085 based on my experience of using this product for several months. First of all, I like its high efficiency. With a minimum input of 9,400 Btu/Hr and a maximum input of an impressive 85,000 Btu/Hr, this boiler does an excellent job of heating space and providing ample domestic hot water. I also like its compact design and wall mount option. A very useful feature is the Wi-Fi functionality. This allows me to monitor and control the boiler remotely via a mobile app, which is convenient and efficient. Overall, the boiler has lived up to my expectations. I would recommend it to everyone!”
