What a full boiler replacement costs in Heritage Mountain

Heritage Mountain is a hillside subdivision in Port Moody built up mostly through the 1980s and into the 1990s, so the housing stock reads younger than a lot of what CANRO services on the east side of Vancouver — but that also means the original mechanical equipment installed when these homes went up is now commonly 25 to 35 years old, right at or past the end of a gas boiler's or water heater's realistic service life.

Replacement covers removing the old boiler and installing a new one, including any code-required updates the original install wouldn't have needed decades ago. That combination runs $7,500–$15,000+ in this neighbourhood, with the wide range reflecting how much of the surrounding system — venting, gas line, expansion tank, controls — also needs updating alongside the boiler itself.

Why original-era Heritage Mountain replacements often run higher

• Code has changed meaningfully since these homes were built — venting clearances, gas line sizing, and expansion tank requirements from the 1980s and 90s don't always match current standards.
• These are sloped lots with attached garages and finished lower levels, and on a fair number of Heritage Mountain properties the water heater or the boiler sits in the garage rather than an interior mechanical room, which is a layout common across 1980s-and-90s Tri-Cities construction.
• Garage installations sometimes need additional protection or clearance work that an interior mechanical room wouldn't.
• Gas and plumbing permits for this address fall under the City of Port Moody, and homeowners renovating an original mechanical room sometimes discover the existing venting or gas line sizing no longer meets current code, which the permit process catches before the work is signed off.

Is replacement the right call?

For a unit already at 25–35 years old showing multiple issues — not just one isolated fault — replacement is usually the more sensible path than continuing to repair piece by piece. A newer condensing boiler also runs differently than the original units common to this era, and a technician evaluating the job will factor in whether the existing venting and gas line can support the new unit or need updating regardless of which model is chosen.

Because a garage isn't insulated the way an interior room is, equipment placed there is exposed to real cold during a hard winter snap — pipes and fittings near an exterior wall or garage door can get close to freezing, which is a factor CANRO's techs specifically check on service calls out here that inland Vancouver properties rarely raise.

Planning a Heritage Mountain replacement

• Get an in-person assessment rather than a phone estimate — garage placement and sloped-lot access both affect the number meaningfully.
• Ask whether your gas line and venting will need updates regardless of which boiler model you choose — that's often the bigger cost driver than the unit itself.
• Time the work outside a hard winter cold snap where possible, since a garage-installed boiler and its piping are more exposed to freeze risk during the job.
