Lochinvar LLC has released the NOBLE™ Fire Tube Combi Boiler. With three models ranging from 110,000 to 199,999 Btuh, the company says the Noble boiler offers easy installation and serviceability, true instantaneous response time, and a user-friendly interface. In addition to 10:1 turndown and 95% Annual Fuel Utilization Efficiency (AFUE), the Noble Fire Tube Combi Boiler is designed, engineered, and assembled in the USA.

The Noble boiler is equipped with Lochinvar’s SMART CONTROL™ and features a setup wizard to guide contractors through programming parameters. The backlit LCD display provides diagnostic information and system status in plain English, not codes.

The Noble boiler’s patented control technology, featuring pre-heat and domestic hot water response modes enable this combi to deliver hot water almost instantaneously during frequent use cycles. For space heating, the Noble boiler’s Air Handler Interlock provides comfort and energy savings. By switching from space heating to domestic hot water mode, it immediately stops non-heated air.
