About the Lochinvar Noble NKB Series

The Lochinvar Noble NKB is a condensing, high-efficiency hot water boiler series aimed at residential and light-commercial heating applications, sold across four output sizes (NKB 080, NKB 110, NKB 150, NKB 199) to match different home and building heating loads. It's a heat-only boiler, so it's paired with a separate domestic hot water tank or indirect tank rather than heating water on demand itself.

In Metro Vancouver, Noble NKB units commonly show up in larger single-family homes with hydronic radiant or baseboard heat, secondary suites, and smaller multi-unit buildings where a single condensing boiler can efficiently cover the full heating load. The stainless-steel fire tube heat exchanger design is built for long service life in our wet coastal climate, provided the venting and condensate drainage are installed correctly.

CANRO's licensed gasfitters and Red Seal technicians service Lochinvar Noble NKB boilers as an independent contractor. We are not a Lochinvar-authorized dealer or factory service centre, and we say so plainly rather than implying an affiliation we don't have.

Signs Your Noble NKB Needs Attention

• Reduced heat output or rooms that no longer reach temperature
• Frequent lockouts, error codes, or the unit failing to ignite
• Short-cycling or unusually long burner run times
• Condensate leaks or corrosion near the vent termination or condensate trap
• Rising gas bills without a matching increase in heating demand
• Circulator pump noise or reduced flow through the heating loop
• Pressure relief valve weeping or an expansion tank that won't hold pressure

Repair & Diagnostics

When a Noble NKB unit locks out or underperforms, our technicians check the gas train, ignition system, heat exchanger, condensate path, and control board before recommending a fix. Every repair visit includes a written diagnosis and a free written quote before we touch anything beyond the initial inspection.

We don't push a replacement when a repair will do, and we don't upsell parts that aren't the actual problem.

Installation & Replacement

For new construction, retrofits, or end-of-life replacements, CANRO handles Noble NKB installation from permit through commissioning, including sizing the unit to your home's actual heating load, venting per current code, condensate neutralization where required, and coordinating Technical Safety BC gas and boiler permits.

Boiler installation typically runs $6,500–$14,000+ depending on unit size, venting complexity, and whether ancillary equipment (pumps, controls, expansion tank) needs replacing too; full boiler replacement projects generally run $7,500–$15,000+. Every quote is written and itemized before work starts.

Parts Replacement

CANRO sources and installs replacement parts for Lochinvar Noble NKB boilers, including:

• Gas valves and gas train components
• Ignitors and flame sensors
• Stainless-steel heat exchangers
• Circulator pumps
• Pressure relief valves (PRVs)
• Expansion tanks
• Combustion air fans
• Temperature and pressure sensors
• Control boards

We confirm parts availability during the diagnostic visit and give you a realistic timeline before ordering anything, with every part quote written and itemized first.

Annual Maintenance & Tune-Up

Condensing boilers like the Noble NKB perform best with scheduled annual maintenance. A CANRO tune-up typically includes combustion analysis, heat exchanger and burner inspection, condensate trap service, gas pressure checks, and safety control testing.

Regular maintenance also supports Technical Safety BC gas safety compliance and is the best way to catch a failing part before it causes an unplanned heat outage during a cold snap.

Common Fault Behaviour

We won't list specific Lochinvar fault codes here unless we're fully confident they're accurate for the Noble NKB control platform, since guessing at codes leads to wasted service calls. In general, repeated lockouts on startup, a unit that fires briefly then shuts down, or nuisance high-limit trips point to a control or combustion issue. Our technicians read the actual fault history off the control panel during the service call rather than diagnosing over the phone.

Cost Guidance

Repair and parts costs vary too much by fault and part availability to quote a number without a technician on site. Every CANRO repair visit starts with a diagnostic call-out and ends with a free written quote. For new installations or full replacement, expect a project in the $6,500–$14,000+ (install) or $7,500–$15,000+ (replacement) range, with final pricing depending on unit size, venting, and ancillary equipment needed.

Rebates & Financing

The federal Canada Greener Homes Grant closed in 2024, but the Canada Greener Homes Loan may still apply to qualifying upgrades, and CleanBC and FortisBC both maintain rebate programs for high-efficiency gas equipment. Program details and eligibility change, so we help confirm current qualifying equipment and paperwork at the time of your project rather than quoting fixed dollar amounts here.
