The KNIGHT heating boiler offers a fully modulating burner with 5:1 turndown and a cascading feature that allows multiple boilers to be controlled by one central boiler. Available in seven models with inputs from 80 to 500 MBtuh, the unit can reduce its heat output as much as 80% without affecting the indoor air temperature. Another key feature is the SMART SYSTEM™ operating control, which has a two-line, 16-character LCD with no alphanumeric codes to decipher.
