Lochinvar Knight Condensing Gas Boiler

The Lochinvar Knight Condensing Boiler is the most innovative gas boiler on the market, with technology that ensures dependable warmth even on the coldest days, and very low energy bills. Every Knight boiler comes with a SMART SYSTEM control. This control is the most advanced boiler control available today. With a large LCD screen and easy-to-use soft keys, SMART SYSTEM gives you a complete database of performance history, and an unprecedented level of control over all system functions.

The SMART SYSTEM control includes an outdoor air reset feature which automatically adjusts the boiler firing rate and supply temperature based on the temperature outdoors. The boiler can fire as low as 20% of it's rated capacity, all the way up to 100%. For example, if the outdoor temperature is 50 degrees F the boiler might fire at only 20% of capacity. As the temperature outside gets colder, the control will automatically increase the firing rate in order to maintain the comfort level in the building. This outdoor reset fucntion saves you a significant amount of energy every day of the year that the outdoor temperature is above the design temperature of the heating system (generally 10 degrees F in this part of the state).

The Knight boiler is Energy Star rated and uses condensing technology to achieve efficiency levels of 95% to 98% AFUE. The boiler can be direct vented using PVC pipe. It comes with a 12 year prorated warranty, with full coverage available for the first 7 years.
