What a Rinnai i-Series boiler replacement looks like across Surrey's dense City Centre and outlying acreage properties.

Quick answer
Replacing an old boiler with a Rinnai i-Series in Surrey means removing the existing unit, running sealed-combustion venting suited to your specific property, and commissioning under a City of Surrey gas permit — the details vary more here than in a smaller municipality given Surrey's size.

Surrey's size means a boiler replacement here can look quite different depending on where you are. In dense City Centre or Whalley townhouse and highrise construction, mechanical rooms are compact and often already set up for a wall-hung unit. In South Surrey or Cloverdale, we're more often replacing an aging atmospheric boiler on an acreage property, where the Rinnai i-Series — a condensing wall-hung boiler in solo (heat-only) and combi versions — goes into a mechanical room originally built for a much bulkier system.
On rural properties still using well water, that's a separate consideration from the install itself but worth flagging for long-term maintenance planning.
The old boiler is disconnected and removed, any chimney venting capped, and new PVC or CPVC venting installed to a sidewall or roof termination. The i-Series connects into the existing hydronic loop, with a condensate line to an approved drain. Commissioning includes gas pressure, combustion, and system pressure checks.
On a larger acreage property, the fitter also confirms the mechanical room has adequate combustion air for the new unit, since older rural installs were sometimes built around a boiler with very different air requirements.
A gas permit through the City of Surrey is required for any boiler replacement, which CANRO pulls as part of the job regardless of which part of the city you're in.
Property type is the biggest cost variable in Surrey — a compact townhouse mechanical room install is generally more straightforward than an older acreage retrofit needing venting and combustion-air updates.
| Item | 2026 ballpark |
|---|---|
| Boiler install | $6,500–$14,000+ |
| Boiler replacement | $7,500–$15,000+ |
These are 2026 public-market ballparks for the region, not a quote — CANRO confirms your actual price after a certified technician assesses your property.
Once the unit is commissioned, the fitter walks you through operation and hands over warranty documentation to register, with terms set by the manufacturer — check your certificate rather than assuming standard coverage. The old boiler is removed and disposed of as part of the job, wherever in Surrey the property sits.
On rebates, FortisBC, CleanBC, BC Hydro, and federal programs all change over time; the Canada Greener Homes Grant is currently closed, though a Greener Homes Loan or FortisBC/CleanBC program may apply depending on your household and equipment, so confirm current eligibility directly. On a rural or acreage property, it's also worth asking your technician whether a water treatment upgrade makes sense alongside the boiler replacement, given the well-water considerations common in parts of outer Surrey.
Given Surrey's size, travel time between neighbourhoods can affect scheduling more than it would in a smaller municipality, so we confirm timing directly with you rather than giving a generic citywide estimate. Whether your property is a Whalley townhouse or a Cloverdale acreage, the fitter plans the visit around your household's needs and gives you a realistic window before work begins, not a vague promise.
Safety note
If you ever smell gas, hear a hissing sound near the boiler, or see soot or scorch marks around the burner compartment, leave the house and call FortisBC's emergency line at 1-800-663-9911 from outside before doing anything else. Do not try to relight a condensing boiler yourself if it has locked out on a flame-loss or ignition fault more than once.
Property type and mechanical room condition matter more than the specific neighbourhood, though acreage and older rural properties sometimes need more work than a newer townhouse install.
Usually one to two days for a straightforward swap; an older rural retrofit can take longer.
Yes, and CANRO pulls that as part of the job.
CANRO installs and services Rinnai equipment as a licensed gas contractor; we don't claim factory-authorized dealer status.
If your property uses well water, higher mineral content can be a longer-term maintenance factor; your technician can discuss what that means for service intervals.
The solo and combi versions can be sized and zoned for larger homes; your technician will confirm the right configuration during the assessment.
