Lochinvar NOBLE NKC199 199 MBH Wall-Hung Combi Boiler Review
The Lochinvar NOBLE NKC199 is a wall-hung combination boiler from Lochinvar (a US-based hydronic specialist). 199K BTU combi providing both space heating and DHW. The NKC line is Lochinvar's residential combi entry.
Specs: 199,000 BTU input, AFUE 95% (condensing), 5.4 GPM DHW at a 70°F rise, modulating burner with 6:1 turndown ratio. Stainless steel heat exchanger. PVC condensing venting. 15-year warranty on heat exchanger.
Lochinvar's positioning emphasizes hydronic-specialist expertise. The brand has stronger commercial market presence than residential, but residential combis like the NKC199 leverage that engineering for home applications.
About $8,500-$11,000 installed depending on hydronic system modifications. Right buyer: medium-large home (2,000-3,500 sq ft) replacing aging boiler + water heater with single high-efficiency combi unit, particularly in regions with established Lochinvar dealer presence (Midwest, Northeast strongest).
