The unparalleled NTI combustion system

NTI's combustion system produces the highest industry
modulation rates, which allows the TRINITY to modulate the burner to the exact size required to meet the conditions of the system. The TRINITY incorporates an electronic state-of-the-art combustion system to reduce the amount of gas that is injected into the burner, to ensure proper combustion throughout the full range of modulation. This system also compensates for extended venting; therefore, adjustments are not required between short and long vent runs. The TRINITY is a totally sealed combustion system: all combustion air is drawn from outside, used for combustion and then expelled. This eliminates any need for fresh air intake into rhe room, thereby decreasing heating costs.

Patented Heat Exchanger

NTI has developed a sophisticated heat exchanger that provides virtually endless hot water, at unheard-of efficiencies. The condenser does not use aluminum but is constructed totally from stainless steel, which is a proven material for condensing appliances.

The TRINITY utilizes its modulation combustion system to electronically increase or decrease the flame size, depending upon the required flow and water temperature. As the water is instantaneously heated and regulated, a storage tank is not required, and energy is not lost due to typical tank standby losses. The TRINITY can deliver up to 5.5 US gallons of water per minute at a constant temperature of 110°F. The TRINITY system automatically gives priority to the domestic hot water system to ensure that all your family's hot water needs are met.
