The TRX is a high-efficiency, wall-hung boiler equipped with an Innovative XTRATECH® stainless steel heat exchanger with large diameter tubing. Every unit is equipped with embedded Wi-Fi connectivity so that the TRX control can easily communicate with NTI remote connectivity tools, making servicing easier. All internal components utilize bayonet quick connectors, eliminating the need to braze or solder within the unit. Swing down control box greatly enhances serviceability, making all major components easily accessible.
