Edgemont's larger custom homes near the mountains rely heavily on radiant floor heat, and CANRO keeps those multi-zone systems balanced through cold snaps.

Quick answer
Hydronic heating in an Edgemont home circulates hot water from a gas boiler through radiant floor tubing or baseboard loops, and the neighbourhood's elevation near Grouse Mountain means the system typically runs more hours through winter than one closer to the water. Zone balancing and catching air or a slow leak early matter more here given the longer, steadier demand these systems see.

Edgemont's larger custom-built homes, particularly from the 1970s onward, are frequently built with radiant floor heating as the primary system, sometimes supplemented by baseboard loops in less-used rooms. Radiant heat suits the neighbourhood's larger floor plans well, distributing warmth evenly across open living spaces rather than relying on forced-air ductwork through multiple levels.
Because Edgemont sits at higher elevation and closer to the mountains than most of North Vancouver, these systems see more consistent demand through a typical winter, which is worth keeping in mind for how often the system should be checked.
It's also common for a custom Edgemont home to have been designed with a large primary bedroom or great room that carries a higher heat loss than a standard-sized room of similar age construction, and those spaces sometimes need a dedicated zone rather than sharing a loop with smaller adjoining rooms. Getting that zoning right at the design stage, or correcting it later if the home consistently underheats one area, makes a meaningful difference to comfort during the coldest weeks of winter.
| Component | Role |
|---|---|
| Boiler | Heats water circulating through the system |
| Manifold | Distributes flow across radiant floor loops |
| Zone valves | Direct heat to whichever area is calling |
| Circulator pump | Moves hot water through each loop |
| Expansion tank | Absorbs pressure changes as water heats and cools |
Uneven heat between floors or rooms is the most common complaint, and in a home with several radiant zones it's usually a manifold balancing issue rather than a fault with the boiler itself. During a hard cold snap, a system that's marginally undersized for the home's total heat loss can struggle to keep up, which shows up as rooms that never quite reach the thermostat's setpoint on the coldest days of the year.
Air trapped in a zone after any plumbing work elsewhere in the house is another frequent cause of a cold room, and it typically resolves once that specific loop is bled at a high point rather than requiring work on the whole system.
A thermostat reading that doesn't match how a room actually feels is worth mentioning to your technician as well, since a sensor placed near a cold exterior wall or in a draft from a window can call for more heat than the rest of the room needs, leading to overheating elsewhere on the same zone while that one spot still feels cool.
Safety note
If you ever smell gas, hear a hissing sound near a gas line or appliance, or notice soot, a persistent headache, or a yellow or flickering burner flame near your boiler or water heater, leave the house immediately and call FortisBC at 1-800-663-9911 from somewhere safe. Gas piping, venting, and combustion appliances must only be installed or serviced by a Technical Safety BC licensed gas fitter.
A system that is marginally undersized for the home's total heat loss can fall slightly behind on the coldest days, especially at Edgemont's elevation. A technician can assess whether the boiler and zoning are adequately matched to the home.
An annual check is generally recommended, and homes at this elevation running longer winter hours may benefit from a technician confirming circulator and zone performance before the coldest months.
This is most often a manifold balancing issue or trapped air in that specific loop, both of which a technician can address without disrupting the rest of the system.
Yes, homes at higher elevation with colder overnight temperatures need a system sized with that additional heat loss in mind, which is something to confirm if you're planning an addition or renovation.
Trees themselves don't affect the hydronic system, but debris from a treed lot can block the boiler's exterior vent termination, which is worth checking during any service visit.
