By James Rolfe, Calgary Hydronics Solutions

There are a myriad of condensing boiler options available on the market today. NTI, or NY Thermal Inc. has been manufacturing boilers since 1968 and condensing boilers since 1997, and is considered by many to be a pioneer in the condensing boiler market.Calgary-Hydronics-Solutions-3

One of the many quality products manufactured by NTI is the Trinity Lx series of condensing boilers. Having extensive installation and service experience with many of the hydronic heating systems made available by NTI, from the first generation T & Ti series boilers, to the Matrix furnace system, which comprises of a high efficiency condensing boiler, hydronic air handler, tankless hot water production and an available integral HRV unit to the Lx series of condensing boilers, I can vouch for the quality and reliability of these units.


The Trinity Lx uses a stainless burner with a metal fiber coating to produce extremely high modulating rates. The interior view of the combustion chamber illustrates the water tube heat exchanger, which is constructed of 316L stainless steel.

With its advanced touchscreen LCD display and Sola control package, this boiler is available in sizes ranging from 150 up to 800 MBH. This model can be used as a closed system boiler in a central heating system or models from the Lx 200 and up can be used as a water heater in conjunction with a storage tank, producing almost endless amounts of hot water for such high hot water consumption needs of restaurants, hotels and car washes to name a few. Capable of producing three separate temperature demands for today’s modern multi-temp hydronic systems with fan coil, DHW and high or low temperature space heating requirements.

Outdoor reset and multi boiler master/slave capable these boilers can detect other Lx boilers in the cascade sequence eliminating the need for an external multi boiler control. Easily set up and programmed using the 7″ touchscreen display all operational parameters can be accessed through the various status screens and menu options.

The NTI Trinity Lx is a quality choice in the highly competitive condensing boiler marketplace of today. Offering flexibility, easy installation and years of energy efficiency in a compact floor or wall mount design.
