The Prestige boiler continues to feature the uniquely designed stainless steel heat exchanger and boasts 95% efficiency across the entire range. The Prestige has the capability to modulate with a turndown ratio of up to 5.5:1. This modulation means the boiler will alter its firing rate to meet the current demand, causing less cyclic behavior and resulting in lower operating costs. The improved ACVMax Control makes configuration quick and easy with setup in 60 seconds or less for standard installations. For unique installations, the 4 circulator outputs are fully configurable for endless customization.
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.
Space Saving High-Performance Wall-Mounted Indirect Water Heater
Pound for pound the S20W is our highest performance tank. With recovery rates that exceed most industry standard 50 and 65 gallon indirects, this small but mighty tank delivers an exceptional amount of hot water.
Fully pickled and passivated, the 444 Stainless Steel tank and coil come in a wall-mounted package complete with a metal jacket to complement the quality look and feel of the NTI boiler line. The CFC-free 2” ultra high density EPS insulation ensures low standby losses and each unit comes complete with a thermostatic mixing valve, tank sensor and T&P valve. A hand hole at the top of the tank allows for inspection and cleaning.
