What replacing a combi boiler involves in a Fleetwood house, where secondary suites, suburban layouts and Surrey permits shape the plan and the price.

Quick answer
Replacing a combi boiler in Fleetwood means taking out the old wall-hung unit that heats the house and makes hot water on demand and fitting a new condensing one, planned around suite demand, basement mechanical rooms, vent and condensate routes and the state of the existing loop. As a ballpark, not a quote, boiler replacement typically runs $7,500 to $15,000+, confirmed by the CANRO office after a short assessment. A Technical Safety BC licensed gas fitter carries out the work under a gas permit.

Most houses in Surrey are heated by forced-air furnaces, so a combi boiler in Fleetwood usually means the owners chose hydronic heat on purpose, or inherited it. The reasons for replacement are ordinary: the existing unit is old and failing, a repair has revealed that parts are hard to find, hot water has become unreliable or the household has changed. A family that once fit comfortably has become a household with a teenager, grandparents or tenants in a basement suite, and hot water demand has risen with it.
That last point is the heart of many Fleetwood conversations. A combi makes hot water as it is used, and a suite adds another shower and another set of taps. We spend real time at the assessment understanding who uses hot water, when and where.
If the basement suite is heated from the same boiler, it may have its own zone and thermostat, and any change to the boiler needs to respect that. The suite is also a hot water consumer. If the main house and the suite might run showers together, a single combi may be pushed, and we may recommend a heat-only boiler with a storage arrangement, or a separate way of making the suite's hot water, instead of promising what a combi cannot deliver. We prefer an honest limit now to a complaint later.
Access matters too. Reaching the boiler, zone controls or piping in a suite means coordinating with the occupant, so we plan the visit and give notice in advance.
If the assessment shows a combi is not the right fit, we say so and explain the alternative.
A modern combi vents through specified pipe instead of a metal chimney, produces condensate that needs a drain, and needs its gas supply checked for full-load demand. Many Fleetwood houses have a boiler in a basement corner with a laundry sink or floor drain nearby, which usually makes condensate simple. Vent terminations on suburban lots generally have room to sit clear of windows and neighbours' property lines, though corner lots, tight side yards and decks can still complicate the choice. The termination must respect the manufacturer's manual and the gas code, and be placed where it will not be blocked by snow or growth.
If the old boiler used an atmospheric flue in a chimney, we address the chimney appropriately, since an abandoned flue can cause moisture and draught problems.
As a ballpark, not a quote, boiler replacement in the Metro Vancouver area typically falls between $7,500 and $15,000+. In Fleetwood the number depends on the vent route, whether the boiler stays put, gas line and meter capacity, the amount of piping changed, the condition of the existing loop, suite zoning and any extras such as filtration or control changes. The CANRO office confirms your price after a short assessment, in writing and before work is scheduled.
| Factor | Simpler | More involved |
|---|---|---|
| Boiler location | Same wall as the old unit | Moved to a new room |
| Vent route | Short run to an outside wall | Long run or roof exit |
| Hot water demand | Small household | Suite and several bathrooms |
| Loop condition | Clean, sound, valves in place | Sludge, leaks, old zones |
| Gas supply | Adequate pipe | Upgrade needed |
On the day, we isolate and remove the old boiler, mount the new one, connect vent, condensate, gas and water, flush and fill the loop, wire the controls and commission the boiler under load, checking heating and hot water, combustion where required and safety devices. We then walk you through the display, the gauge and routine care. A gas permit is taken out through Technical Safety BC and the work is inspected. CANRO holds gas licence LGA0043870 and boiler licence LBP0046450.
Building-side matters, such as structural changes, are handled by the City of Surrey, while gas permits go through Technical Safety BC and FortisBC supplies the gas. Surrey is served by Metro Vancouver's soft water, which is kind to the domestic side of a combi, though sediment and particles can still restrict small passages, and an inlet filter is worth discussing. Suites in Surrey homes are common, and we confirm that any work respects how the suite is heated.
A little preparation makes replacement day smoother. Clear the area around the old boiler, including stored boxes and shelves, and clear a path from the door to the mechanical room. Let anyone living in the suite know the plan. Protect finished floors along the route if you wish, though our technicians lay down coverings as a matter of routine. Make a note of which taps and rooms use the most hot water so we can confirm the plan against real use, and be prepared for a short period without heat and hot water while the swap takes place.
Warranty terms are set by the manufacturer, so verify your certificate. We recommend yearly service, a clear space around the boiler, a clear vent termination and working CO alarms on each level, including the suite. If anything seems off in the first weeks, the CANRO office wants to hear about it.
Safety note
If you smell gas, leave the home immediately, avoid switches and phones inside, and call FortisBC at 1-800-663-9911 from outside. If a carbon monoxide alarm sounds, everyone leaves and 911 is called. Boiler replacement involves gas piping, venting and combustion equipment and must be done by a Technical Safety BC licensed gas fitter; CANRO holds gas licence LGA0043870 and boiler licence LBP0046450.

Sometimes, but simultaneous hot water use can strain a combi. We assess how the house and suite use hot water and advise honestly, including alternatives.
Heat is off while the boiler is being replaced, and we plan to keep that period as short as we reasonably can. We coordinate access and notice with the occupant.
Yes. A gas permit through Technical Safety BC is required and taken out by the licensed contractor. CANRO handles this.
Often yes, if the clearances, vent and condensate routes suit. We confirm at the assessment.
No. We assess what suits your house and explain options. We are not an authorized or factory dealer for any brand.
