What an IBC gas boiler installation looks like across Coquitlam, from older Maillardville radiator systems to new Burke Mountain radiant floors.

Quick answer
An IBC gas boiler installation in Coquitlam spans two very different scenarios: retrofitting older cast-iron radiator systems in established neighbourhoods like Maillardville, and sizing new radiant in-floor systems for newer construction higher up on Burke Mountain. A licensed installer calculates heat loss specific to the home, checks venting and gas supply, and accounts for elevation on hillside properties.

Maillardville and other established Coquitlam neighbourhoods have a number of older homes still running cast-iron radiators from a legacy boiler system. A retrofit typically replaces the boiler and controls while keeping sound existing radiator piping in service.
A technician checks the piping for corrosion, flushes accumulated sediment from the system, and confirms each radiator still circulates properly before connecting the new boiler.
Newer construction higher up on Burke Mountain more commonly uses radiant in-floor heating rather than radiators, which changes the boiler sizing and zoning approach considerably, since in-floor loops typically run at lower water temperatures than baseboard or radiator systems.
Elevation and greater wind exposure on the mountain also factor into the heat loss calculation, since these homes can see colder conditions during winter cold snaps than homes closer to the Fraser River.
A licensed technician calculates heat loss room by room and zone by zone rather than relying on square footage alone, since radiant floor and radiator zones often need to be controlled separately within the same home.
Gas boiler installation in Coquitlam requires a permit through the City of Coquitlam, with inspection required before the job is complete.
Venting requirements depend on whether the unit is a condensing or non-condensing design, and a technician confirms the mechanical room location supports the required venting path.
| Neighbourhood type | Common system |
|---|---|
| Older Maillardville home | Cast-iron radiators, boiler and controls retrofit |
| Newer Burke Mountain build | Radiant in-floor loops, elevation factored into sizing |
The technician isolates gas and water, drains and flushes the existing system where applicable, sets the new boiler, connects gas, venting, and hydronic piping, and pressure-tests before startup.
Each zone is checked for circulation and correct water temperature, and controls are set and explained before the visit ends.
A radiant in-floor system and a cast-iron radiator system have different service priorities: in-floor loops benefit from periodic checks of mixing valve performance and water temperature, while radiator systems need attention to bleeding air and checking for slow leaks at older fittings.
If your Coquitlam home combines both, as some renovated properties do, make sure your annual service covers each zone type separately rather than treating the whole system as one uniform loop.
If you're planning a renovation that adds square footage or converts a garage to living space, loop in your heating contractor early, since new areas need their own heat loss calculation and may call for an additional zone rather than simply extending an existing one.
Safety note
If you ever smell gas near the boiler, hear an unusual venting sound, or suspect a carbon monoxide issue, leave the home immediately and call FortisBC's emergency line at 1-800-663-9911 from a safe location. Gas piping, venting, and combustion setup on a boiler must only be handled by a Technical Safety BC licensed gas fitter; CANRO holds gas licence LGA0043870 and boiler licence LBP0046450.
Often yes, if the existing piping is in good condition; it's checked for corrosion and flushed of sediment before the new boiler is connected.
Yes, radiant floor loops typically run at lower water temperatures than radiator systems, which affects sizing and how the system is zoned and controlled.
Yes, higher elevation and greater wind exposure increase heat loss, which is factored into the boiler sizing for homes further up the mountain.
Yes, gas boiler installation requires a permit through the City of Coquitlam and must pass inspection.
Yes, with separate zones controlled independently, since the different systems typically need different water temperatures.
Leave the home immediately and call FortisBC's emergency line at 1-800-663-9911 from a safe location rather than checking it yourself.
Often yes; new living space typically needs its own heat loss calculation and may call for a dedicated zone rather than extending an existing one.
A single-zone retrofit with usable existing piping often takes most of a day, while homes combining radiant floor and radiator zones can take longer to set up correctly.
