A combi boiler replaces both your furnace-style heat source and your hot water tank with one unit, and Glenayre's older homes usually need some piping rework to make that swap.

Quick answer
Installed combi boilers in Glenayre run roughly $9,000 to $16,000, a ballpark based on 2026 public market data rather than a fixed quote — the CANRO office and our certified gas technicians confirm actual pricing after seeing your mechanical room and current piping layout. The spread mostly reflects how much of your home's existing hot water and heating piping needs to be reconfigured to feed off one unit instead of two separate systems.

A combi unit is doing two jobs — space heating and domestic hot water — out of one heat exchanger and one set of controls, so the appliance itself is more sophisticated than a heat-only boiler, and the installation usually touches more of the house. In a lot of Glenayre homes that currently run a separate hot water tank alongside a boiler or furnace, converting to a combi means removing the old tank, rerouting the domestic hot water lines to the new unit, and re-piping the heating loop to the combi's connections.
Because these are 1960s-to-80s split-levels and ranchers for the most part, the existing piping runs weren't designed with a combi in mind, so a fitter often has to open up a section of wall or floor to reroute lines cleanly rather than just swapping the box on the wall.

|---|---|
| Combi boiler installed | $9,000–$16,000 |
| Municipal gas permit (District of North Vancouver) | $75–$200 |
A common call here involves a split-level with an old standalone tank in the crawlspace and a separate boiler feeding baseboard heat upstairs — the homeowner wants to consolidate both into one combi unit to free up floor space. That means the domestic hot water lines, which currently run off the tank, need to be rerouted to the new combi, and the old tank needs to come out entirely. Because the crawlspace access is tight, a fitter often plans the piping route before demo starts rather than improvising once the old equipment is out.
Households with a renovated ensuite bathroom or a basement suite tend to ask the most detailed sizing questions, since a combi's flow-rate ceiling matters more when two showers might run at once. Working through actual fixture count and typical morning usage patterns during the assessment is what keeps a combi from feeling undersized after it's installed.
Combi units work well where floor space is tight, since you free up the footprint a standalone tank used to occupy — useful in some of Glenayre's smaller basement mechanical rooms. The trade-off is hot water flow rate: a combi delivers hot water on demand rather than from stored volume, so a household running two showers plus a dishwasher at once needs a unit sized for that peak load, not just average daily usage. A technician doing the quote should ask about your actual fixture count and simultaneous-use habits before recommending a size.
Because North Shore reservoir water is soft, scale isn't the main long-term concern for a combi's heat exchanger here the way it can be in hard-water regions — but annual service still matters for the ignition and flow components that do the real work.
Safety note
If you ever smell gas or suspect a flue or venting problem near a boiler or water heater, leave the house and call FortisBC at 1-800-663-9911 from outside before doing anything else. Never troubleshoot a suspected gas leak yourself.
A combi heats hot water on demand as you use it, with no storage tank, while a regular boiler paired with a separate tank keeps a reserve of hot water ready. Combis save floor space but have a flow-rate limit.
Possibly. Combis can have higher instantaneous gas demand than a tank-fed system, so the technician checks your line and meter sizing as part of the quote.
It depends on the unit's flow rate and your home's demand — this is exactly what a proper sizing assessment is for, rather than guessing from square footage.
Disposal of the old tank and boiler, if applicable, is usually included in a full conversion quote, but confirm it's itemized so there's no surprise.
Plan for two to four days when re-piping is involved, longer than a like-for-like boiler swap because of the extra plumbing work.
The District of North Vancouver's permit and inspection process adds a scheduling step, but a licensed contractor builds that into the timeline rather than starting work unpermitted.
