What CANRO's licensed technicians look for on a Navien NFB-H replacement call in New Westminster, and what it costs as a 2026 ballpark, not a quote.
Tell us what you need—we’ll call you back fast.
Quick answer
Replacing a Navien NFB-H makes sense once the heat exchanger has failed, repairs keep recurring, or the unit is near the end of its service life; CANRO assesses the specific unit in New Westminster before recommending it rather than defaulting to replacement. The process runs through an in-home assessment, a written quote, a mechanical permit, and a scheduled install.

Replacing rather than repairing generally makes sense when the heat exchanger is the failure, when unrelated repairs keep piling up, or when the boiler has reached the point where its remaining service life is short.
A lot of the city's housing dates to the early 1900s through the 1950s, with steep lots between uptown and the riverfront, cast-iron radiators, and mechanical rooms that were never designed for modern equipment clearances.
CANRO handles replacements across one of the oldest cities in the Lower Mainland, and the assessment always starts with looking at what's actually failing in the old system before recommending a specific path forward.
In this configuration, combustion gas moves through tubes surrounded by water rather than water moving through fire-side tubes, and that generally makes the unit more forgiving of mineral buildup.
As a condensing unit it extracts extra heat before exhausting, which is why a condensate drain and PVC venting are part of the install; as a heat-only unit, it doesn't supply hot water, so that job falls to a separate appliance if needed.
CANRO isn't a Navien-authorized dealer; what we provide is licensed installation and service, and warranty coverage is a separate matter set by Navien's own registration process.
New Westminster is on Metro Vancouver's treated supply, so water hardness is not the driving issue for scale here.
The steep grade between uptown and downtown New West means some homes have their utility space below street level, which changes how a condensate line drains and how a flue is routed to daylight.
the City of New Westminster handles mechanical permits here, and a boiler replacement always needs one pulled before work starts, along with an inspection once it's done.
CANRO opens with a site visit to assess venting, gas line size, electrical supply, condensate disposal, and the heating loop the boiler serves, then puts together a written quote.
After the quote is accepted, the permit is pulled and the install scheduled; on the day, the old boiler is taken out, the new one set and connected, vented and commissioned, then tested through a full cycle before the crew leaves. A basic replacement is often fast, while venting changes or gas line work add time, and CANRO gives a realistic estimate rather than a rushed promise.
As a 2026 public-market ballpark, not a fixed quote, confirmed by CANRO after a short site visit, boiler installs generally run $6,500-$14,000+ and full replacements with old-unit removal run $7,500-$15,000+, with venting and gas work the biggest factors in where you land.
| Repair vs. replace signal | Usually means |
|---|---|
| Heat exchanger has failed | Replace |
| Repeated unrelated faults in a short span | Replace, or repair once more and reassess |
| Single component failure, unit otherwise sound | Repair |
| Unit is near the end of its expected service life | Replace |
Safety note
Natural gas boilers burn fuel and vent combustion gas, so anything involving the gas line, the burner, or the flue is gas-fitting work under the BC Safety Standards Act. If you ever smell gas near the mechanical room, hear a hissing sound at a fitting, or the CO alarm sounds, leave the house and call FortisBC's emergency line at 1-800-663-9911 before doing anything else. Never reset a boiler that has locked out on a safety fault more than once, and never remove a flue or vent component yourself.
Yes -- every Metro Vancouver municipality requires a mechanical or gas permit for a boiler replacement, and CANRO pulls it as part of the job.
Often yes, but a fire-tube condensing unit vents differently than an older atmospheric boiler, so the technician checks whether the existing flue path and condensate drain still work or need changes.
It can work well, though it hits its best efficiency at lower water temperatures, so the technician sizes the system to your existing radiators during the assessment rather than assuming a fit.
CANRO disconnects and removes the old unit as part of the replacement, so there's nothing extra to arrange for disposal.
Usually yes -- a unit still within its expected service life is normally worth repairing unless the fault is in the heat exchanger itself, which a technician can confirm during diagnosis.
