The Lochinvar Noble Combi, sold under the NKC model designation (NKC110, NKC150, and NKC199), is a wall-hung, fully condensing combi boiler that provides both space heating and on-demand domestic hot water from one compact unit. It's a practical fit for Vancouver-area townhomes, laneway homes, and smaller single-family properties where mechanical room space is limited and a separate hot water tank isn't wanted. The NKC line is a sealed-combustion, condensing appliance in the mid-90s AFUE efficiency class with modulating burner control, and it vents through PVC/CPVC or similar plastic pipe rather than a masonry chimney.
CANRO's licensed technicians work on Noble NKC combi units installed across Burnaby, Vancouver, Coquitlam, Richmond, Surrey, and the rest of Metro Vancouver. Whether your NKC110, NKC150, or NKC199 was installed last year or a decade ago, our crews carry the diagnostic tools and common parts to get it running again quickly.
When a Noble NKC stops performing, our technicians run a full diagnostic: checking incoming gas supply and pressure, inspecting venting and condensate drainage, testing the ignition sequence, and pulling any fault codes from the control board. Because the NKC is a sealed, pressurized combi system, we also verify system water pressure and expansion tank precharge, since a waterlogged expansion tank or low system pressure is one of the more common causes of nuisance lockouts on units like this.
Once we've identified the fault, we explain what we found and provide a free written quote before starting any repair. Same-day and after-hours service is available for no-heat and no-hot-water calls, which matters most during a Vancouver cold snap when a failed combi boiler leaves a home without heat overnight.
For homeowners installing a new Noble NKC or replacing an older boiler, CANRO handles the full scope of work: gas line and venting design, condensate neutralization and drainage, system flushing, and commissioning. As an independent licensed contractor, we aren't tied to selling one brand, so we'll size and spec a Noble NKC honestly against your home's heat loss and hot water demand rather than defaulting to whatever's easiest to install.
Every install includes the required Technical Safety BC gas permit and inspection. In Metro Vancouver's climate, venting termination clearances, condensate freeze protection, and combustion air routing all need to be done correctly, and our Red Seal-certified gasfitters treat that as standard practice, not an extra step.
Combi boilers pack a lot of components into a small chassis, and most Noble NKC failures trace back to a short list of parts that wear out over time. CANRO stocks or can source the following for Metro Vancouver customers:
We diagnose first to confirm the actual failed component rather than guessing, then provide a free written quote for the part and labour. For customers further out in the Fraser Valley where distributor lead times can run longer, we'll give you an honest timeline on parts availability up front.
A licensed CANRO technician can assess it honestly — no supplier quotas, no pressure.
📞 (604) 359-1081Request a free quoteCombi boilers benefit from annual servicing more than standalone heat-only boilers, since the same heat exchanger handles both space heating and domestic hot water duty year-round. A CANRO tune-up on a Noble NKC includes combustion analysis, cleaning the burner and heat exchanger, checking the condensate trap and drain for blockages, verifying system pressure and expansion tank precharge, inspecting venting for deterioration, and testing safety controls. Regular maintenance is one of the simplest ways to avoid a mid-winter no-heat or no-hot-water call.
Lochinvar's Noble control boards display fault codes on the front panel, but exact code numbering can vary across firmware revisions, so we won't guess at specific codes here. In practice, the failures we see most often on NKC combi units present as: ignition lockout after repeated firing attempts, low system pressure lockouts, flow sensor faults causing erratic hot water temperature at the tap, and condensate blockage faults that prevent the unit from firing at all. If your display is showing a fault code, note it down before calling so our technician can look up the exact meaning for your specific NKC model on-site.
Repair and parts pricing depends on the failed component and labour time, so we don't quote dollar figures sight unseen — every repair starts with a diagnostic visit and a free written quote before we proceed. For a new installation, a typical Noble NKC combi boiler install in Metro Vancouver runs in the range of $6,500 to $14,000 or more depending on venting complexity, gas line work, and system design. Full boiler replacement, including removal of the old unit, generally falls between $7,500 and $15,000 or more. We'll give you an exact number in writing once we've assessed your home.
The federal Canada Greener Homes Grant closed in 2024, but the Canada Greener Homes Loan is still available for qualifying efficiency upgrades, and CleanBC continues to run rebate programs for high-efficiency gas equipment. FortisBC also offers its own rebate programs for qualifying condensing boilers and combi systems. Eligibility and amounts change regularly, so we'll help you check what applies to your specific Noble NKC installation at the time of your project rather than quoting figures that may be out of date.
