Brentwood's remaining 1960s and 1970s houses and townhome complexes each need their own boiler sizing approach, which is where an in-home assessment earns its keep.

Quick answer
A wall-hung gas boiler mounts on a wall rather than the floor, and in Brentwood it typically replaces an aging unit in one of the area's remaining single-family houses from the 1960s and 1970s or in a low-rise townhome complex along the Lougheed corridor. Installation involves a heat-loss calculation for the home's radiators or hydronic loop, gas line and meter checks, a sealed vent run to an exterior wall, and a City of Burnaby gas permit pulled by a licensed fitter. Townhome complexes add a wrinkle, since a boiler may serve a single unit or, less commonly, a small cluster, and the fitter needs to know which arrangement is in place before sizing anything.

Brentwood has transformed rapidly around its town centre, with new high-rise towers replacing much of what used to be single-family housing, but a meaningful stock of older houses and 1970s and 1980s townhome complexes remains further from the core along streets like Willingdon and Beta Avenue. These older properties are where a wall-hung boiler installation project usually starts: a floor-standing unit at or past the end of its practical service life, in a mechanical space that was never designed with a wall-mounted appliance in mind but adapts to one easily.
In townhome complexes specifically, each unit typically has its own boiler serving that unit alone, though the exact arrangement varies by complex, so the first step in any Brentwood townhome job is confirming whether the homeowner's boiler is a standalone unit or shares any piping with a neighbouring unit.
A single-family Brentwood house from the 1960s or 1970s generally has a larger heating load, more radiators or a longer baseboard run, than an individual townhome unit of similar age, and the fitter's heat-loss calculation reflects that directly rather than assuming a one-size answer across the neighbourhood. Hot water demand also differs: a family home with several bathrooms draws differently than a two-bedroom townhome unit, which affects whether a combi wall-hung boiler makes sense or a boiler paired with a separate tank is the better fit.
A gas permit through the City of Burnaby is required for the installation, pulled by the licensed fitter, and the sealed combustion vent runs through PVC or polypropylene pipe to an exterior wall with clearances set by the manufacturer's manual and the CSA B149.1 code. In a townhome complex, the homeowner should also check whether the complex's governing documents require notice or approval before any exterior vent penetration is added or altered, since that is a separate matter from the municipal permit itself.
The inspection and sign-off process is otherwise the same as for a single-family home: the City inspects the completed gas line, venting and combustion performance before the work is closed out.
| Housing type | Typical mechanical space | Sizing note |
|---|---|---|
| Single-family house (1960s-70s) | Basement utility room | Larger heating load; combi capacity depends on bathroom count |
| Townhome unit | Small closet, often near the entry or garage | Confirm unit is independently served before sizing |
| Low-rise apartment (individual units) | In-suite mechanical closet | Space is usually the limiting factor for model choice |
As a ballpark, not a quote, a wall-hung gas boiler installation runs roughly $6,500 to $14,000 or more in the Metro Vancouver market, with a smaller townhome unit typically landing toward the lower end and a larger single-family home with more radiators or a combi model at the higher end. CANRO's office confirms a firm figure after a short assessment of the specific home or unit.
Safety note
Gas line, venting and boiler installation must be performed by a Technical Safety BC licensed gas fitter, and any shared mechanical arrangement in a multi-unit complex should be confirmed before work begins. If you smell gas or suspect a venting or carbon monoxide problem, leave the home and call FortisBC at 1-800-663-9911 from a safe location.
Most townhome units have their own independent boiler, but arrangements vary by complex, so it is worth confirming before assuming your unit's system is fully separate from your neighbours'.
Check your complex's governing documents, since many require notice or approval before any exterior vent penetration is added or altered, separate from the City of Burnaby gas permit itself.
Often yes, since a townhome's lower hot water demand compared with a larger single-family home suits a combi unit's flow-rate capacity well, though the specific fixture count still needs to be checked.
A single-family house generally has a larger heating load and more radiators or baseboard length than an individual townhome unit, so the heat-loss calculation and boiler capacity differ accordingly.
Yes, a gas permit is required for any gas boiler installation or replacement regardless of housing type, and the completed work is inspected.
Generally yes, since it is designed to mount on a wall in a compact space, which is typically easier to fit than the floor-standing unit it replaces.
