What the Triangle Tube Prestige Excellence Is

The Prestige Excellence is Triangle Tube's condensing hot water boiler with an integrated stainless steel domestic hot water tank built into the same cabinet. Rather than pairing a boiler with a separate indirect tank on the floor beside it, the Excellence packages both into one wall-hung-style unit, which is why it shows up so often in Greater Vancouver homes where mechanical rooms are tight — Vancouver Specials, townhouses in Burnaby and Coquitlam, and older character homes converted to hydronic heat.

Like the rest of the Prestige family, the Excellence is a fully condensing boiler in the mid-90s AFUE class, built around a stainless steel fire-tube heat exchanger. It modulates its firing rate to match the heating load, extracts extra heat from flue gases, and drains the resulting condensate — all of which makes it efficient, but also means it has more components that need periodic attention than the cast-iron boilers it typically replaces.

Because it supplies both space heating (radiators, baseboards, or in-floor loops) and domestic hot water from one appliance, a fault on a Prestige Excellence usually means a household loses heat and hot water at the same time. That is why we prioritize these calls, especially during Lower Mainland cold snaps when demand on the boiler is highest.

Signs Your Prestige Excellence Needs Repair

Prestige Excellence boilers are generally reliable, but after years of service in our wet coastal climate certain symptoms show up repeatedly on the units we see across Metro Vancouver:

• Lockouts or repeated ignition attempts — the boiler tries to fire, fails, and displays a fault on the control panel
• Heat works but domestic hot water runs lukewarm or runs out quickly — often the integrated tank side, its sensor, or the diverting/priority control
• Short cycling — the boiler fires and shuts down every few minutes instead of modulating smoothly
• Rising gas bills with no change in habits — a sign the heat exchanger or combustion settings need attention
• Water on the floor under the unit — condensate line blockage, a weeping pressure relief valve, or a failing internal component
• Kettling, gurgling, or banging noises from the boiler or piping
• System pressure repeatedly dropping to zero or climbing too high — expansion tank or fill/relief issues
• Flue or fresh-air intake problems — sidewall vents on BC homes can be blocked by debris, ice during cold snaps, or nesting

If you notice any of these, it is worth booking a diagnostic before a small fault turns into a no-heat call in January. If you ever smell gas, treat it as an emergency — see the safety note below.

Prestige Excellence Repair & Diagnostics

Our Red Seal certified gasfitters carry combustion analyzers and the manometers, multimeters and pressure gauges needed to diagnose a condensing boiler properly — not just swap parts until something works. On a Prestige Excellence diagnostic visit we typically check the fault history on the control, measure gas pressure, verify flame signal at the ignition electrode and flame sensor, inspect the condensate trap and drain, test the circulator and system pressure, and run a combustion analysis to confirm the burner is set up correctly for the installed venting.

The Prestige control displays fault conditions when the boiler locks out. Rather than quoting specific code numbers here — which vary by control version — we recommend noting whatever the display shows and telling us when you call. Common fault categories on this series are ignition failures (often flame sensing or gas supply related), blocked flue or condensate faults, high-limit trips from poor circulation, and sensor faults on the heating or domestic hot water side. Each points our technician to a different part of the system, so the display message genuinely speeds up your repair.

We charge a diagnostic visit fee and then provide a free written quote for the repair before any work proceeds, so you always know the cost before committing. Most repairs are completed the same visit because we stock common condensing-boiler parts on our trucks.

Parts Replacement for the Prestige Excellence

Triangle Tube is well distributed in Canada, and parts availability for the Prestige line in Metro Vancouver is good — most components can be sourced from local hydronic wholesalers within a day or two, and the most commonly failing items we keep in stock. Parts we regularly replace on Prestige Excellence boilers include:

• Ignition electrodes and flame sensors — the most frequent wear items on any condensing boiler; carbon buildup causes ignition lockouts
• Gas valves — replaced when they no longer regulate properly or fail electrically; always followed by combustion analysis
• Combustion fans (blowers) — bearing noise or failure to prove air flow triggers lockouts
• Condensate traps and drain components — Vancouver's long heating season produces a lot of condensate; blocked traps shut the boiler down
• Temperature sensors — supply, return, flue and domestic hot water sensors that drift or fail open
• Control boards — replaced when diagnostics rule out sensors and wiring
• Circulator pumps — internal or system circulators that seize, leak, or run noisily
• Pressure relief valves (PRVs) — a weeping PRV is replaced, but we also find and fix the cause, often a waterlogged expansion tank
• Expansion tanks — failed diaphragms cause pressure swings and PRV discharge
• Heat exchanger service — the stainless fire-tube exchanger is durable, but combustion-side cleaning and gasket replacement are routine; full exchanger replacement is quoted against the cost of a new boiler so you can make an informed call

For any part replacement we quote in writing after diagnosis rather than publishing flat prices, because access, part version, and what else the fault has affected all change the scope. If your Excellence is still within Triangle Tube's warranty period, we will tell you honestly what may be covered and help with the claim paperwork — as an independent licensed contractor we work for you, not the manufacturer.

Installation & Replacement in Greater Vancouver

If you are considering a Prestige Excellence for a new installation, or your existing one has reached the end of its life, CANRO handles the full project: heat-loss-based sizing, Technical Safety BC gas permit, removal of the old equipment, venting and condensate design, commissioning with a combustion analyzer, and registration of the manufacturer warranty.

The combined boiler-plus-DHW format suits many Lower Mainland homes, but it is not automatic. Households with very high hot water demand sometimes do better with a separate boiler and larger indirect tank; small condos may not need the storage at all. We size against your actual radiation and hot water use rather than simply matching the old unit's rating — oversized condensing boilers short cycle and never reach their efficiency potential.

BC installation realities we plan for on every job: sidewall or roof venting in approved plastic vent material with correct slope and clearances, a condensate route that will not freeze during cold snaps and that neutralizes acidic condensate where required, seismic strapping and gas-line sizing per code, and the municipal and Technical Safety BC permits and inspections that protect you at insurance and resale time. Boiler installation in Greater Vancouver typically runs $6,500–$14,000+, and replacement of an existing boiler $7,500–$15,000+, depending on venting changes, piping corrections, and site access. Every project gets a free written quote before work begins.

Annual Maintenance & Tune-Ups

Condensing boilers are not install-and-forget appliances, and Triangle Tube's warranty terms — like every manufacturer's — expect regular servicing. An annual tune-up on a Prestige Excellence pays for itself in efficiency and avoided mid-winter breakdowns. A CANRO maintenance visit includes:

• Combustion analysis and burner adjustment to keep the boiler in its efficient condensing range
• Inspection and cleaning of the burner, ignition electrode and flame sensor
• Combustion-side heat exchanger inspection and cleaning as needed
• Condensate trap cleaning and drain flush — the single most preventable cause of winter lockouts
• System pressure, expansion tank charge, and pressure relief valve check
• Venting and combustion-air intake inspection, inside and at the exterior termination
• Domestic hot water performance and temperature check on the integrated tank side
• Control settings review — outdoor reset and DHW priority set up correctly for the home
• Gas leak test at accessible fittings and a written condition report

The best time to book is late summer or early fall, before the first cold snap fills every heating contractor's schedule in the Lower Mainland.

Common Fault Behaviour on This Series

A few patterns come up often enough on Prestige Excellence calls in Metro Vancouver that they are worth knowing. Ignition lockouts that clear on reset but keep returning usually trace to a worn ignition electrode, weak flame signal, or marginal gas pressure — resetting repeatedly without fixing the cause just stresses the components. Lockouts during heavy rain or freezing weather often point to the condensate system: our long, damp heating season produces litres of condensate daily, and a partly blocked trap or a drain line exposed to freezing will shut the boiler down at the worst possible time.

Lukewarm domestic hot water with normal space heating usually involves the integrated tank's sensor or the control's DHW priority logic rather than the burner itself — often a quick fix once properly diagnosed. And pressure-related shutdowns almost always come back to the expansion tank or a small system leak, not the boiler. A methodical diagnosis is cheaper than replacing parts on speculation, which is exactly how we approach every call.

What Prestige Excellence Service Costs

For repairs and parts we do not publish flat prices, because a flame sensor swap and a control board replacement are very different jobs. Instead, you pay a diagnostic visit fee, we find the actual fault, and you receive a free written quote before any repair work starts — no surprises, and no pressure to proceed. For bigger decisions, the honest numbers in our market are: new boiler installation $6,500–$14,000+ and boiler replacement $7,500–$15,000+ in Greater Vancouver, with the final figure depending on venting, piping, and access. When a repair quote climbs toward a meaningful fraction of replacement cost on an older unit, we will tell you plainly and let you decide.

Rebates & Financing

If you are replacing a Prestige Excellence or upgrading to one, it is worth checking current incentive programs before you commit. The federal Canada Greener Homes Grant closed to new applicants in 2024, but the Canada Greener Homes Loan remains available for eligible home energy retrofits, and BC homeowners can look at CleanBC and FortisBC rebate programs, which change their qualifying equipment lists and amounts periodically. We will tell you during the quote which programs your specific project may qualify for and what documentation the programs require — we do not quote rebate dollar figures until we have confirmed them against the current program rules, because published amounts change. Financing options are also available on installations; ask when you call.
