A very impressive boiler system. We installed the NTI TRX150C during a renovation project, and it has performed better than expected.
The biggest advantage for us was having one compact unit handle both heating and hot water. It simplified the mechanical setup while still providing excellent performance for our home.
The controls are straightforward, the operation is quiet, and the temperature consistency has been excellent. After using it through the winter, we are very happy with the reliability and overall build quality.
A great choice for homeowners looking for an efficient combi boiler solution.

Choosing the NTI TRX150C was a big decision for us because our old boiler was nearing the end of its life, and we wanted something that could handle both heating and hot water more efficiently.
From the first weeks of operation, we noticed a major improvement in comfort. The house heats more evenly, and we no longer experience the temperature swings we had with our previous system. The domestic hot water performance has also been excellent — showers stay consistent, and we do not have to worry about running out during busy mornings.
One of the things that stood out to us was how compact the unit is compared to traditional boiler-and-water-heater combinations. The wall-hung design saved valuable floor space, and the installation looks much cleaner overall.
We also liked that the TRX150C uses condensing technology and has a stainless steel heat exchanger, which gave us confidence that we were investing in a durable system designed for long-term use. Efficiency was another important factor, since heating costs are a major concern during winters.
After going through a full heating season, we can confidently say this was the right choice. The system is quiet, dependable, and has made our home much more comfortable.

The NTI TRX150C has been a fantastic replacement for our old heating system. We wanted to upgrade to a combi boiler for reliable home heating and a better hot water solution, without the need for separate equipment taking up space.
This unit has worked extremely well for our household. The heating response is much faster than that of our previous boiler, and the hot water supply has remained consistent even as demand increases. Its design also made a big difference by giving us more usable space in our utility room.
The system operates quietly and looks clean after installation, compared to our previous setup. Very impressed with the overall performance and quality.

The boiler met all expectations. Easy to use, quiet and, most importantly, economical.
NHB integrated control provides industry-leading options and features including adjustable heat capacity, temp boost for outdoor reset control, adjustable anti-cycle timer and freeze protection.
The condensing technology of the dual stainless steel heat exchangers saves energy, reduces greenhouse gasses.
1/2″ gas pipe capability up to 24′ (subject to local codes). Cuts installation time, no need to install new gas lines for retrofit applications.
The sophisticated gas flow control system provides a high turndown ratio which reduces energy waste and excessive boiler cycling.
