Radiant Floor Heating - Lochinvar Boilers
For more than 80 years, Lochinvar has played a legendary role in commercial water heating. Now we're bringing that proven performance to the condensing market with the KNIGHT—today's most advanced fully modulating high-efficiency condensing boiler.
The KNIGHT is an installer's dream: lightweight and compact, with key components that are easy to access. The KNIGHT offers PVC venting versatility, rugged reliability, seven models with inputs ranging from 80,000 to 500,000 Btu/hr, and 93% DOE AFUE.
And you'll love the SMART SYSTEMª control, which includes a service indicator, contractor accessible password protection, and a 2-line display with simple fault descriptions, not codes. Best of all, the KNIGHT offers more standard features than any other heating boiler available today—including outdoor reset and a boiler circulating pump supplied with every KB 080-285 unit. Plus every KNIGHT is backed by an outstanding 12-year warranty.
