The NTI Trinity FireTube is easy to install and maintain. It is a down-fired, Fire Tube stainless steel boiler with top and bottom supply/return piping made from robust stainless steel. All NTI units come with the certified internal low water cut-off with test button for your piece of mind.

Featuring a fully-modulating combustion system, condensate pump receptacle, built-in gas drip leg and wall-mount configuration with optional floor stand, the Trinity system is a smart, reliable and advanced alternative. And with a high quality metallic clear coat finish, the sleek look can even improve the style of a room.


Navien’s Condensing Technology offers high efficiency, money and energy savings over tank type water heaters and traditional water heaters. The two stainless steel heat exchangers provides longer life expectancy as they are highly resistant to corrosion and erosion compared to copper heat exchangers while still reducing minerals deposits.

New metal fiber burner is designed to deliver a consistent air/gas mixture improving combustion efficiency resulting in less acid rain and less green house effect. Comply with SCAQMD 1146.2 strict NOx emissions standard.
