NTI Boilers has introduced upgrades to its current flagship wall hung condensing boilers, the TRX and FTVN. The two condensing wall hung boilers now offer a brand new user interface for an enhanced user experience and easier set-up and troubleshooting for the contractor. The new technology upgrades allow for easier set-up and troubleshooting on NTI’s TRX Series II and FTVN Series II boilers. Standard features on the boilers include factory-supplied capabilities for two zones, an EXTRATECH stainless steel heat exchanger, and integrated and easily-serviced direct hot water filter and boiler kit.
