How Much Does Tankless Water Heater Installation Cost in Port Moody, BC?
Typical cost in Port Moody
$5,450
$3,700 low · $7,350 high
All-in installed price: unit, gas & venting, labour & permit · Updated July 2026
Installing a tankless water heater in Port Moody costs $3,700 to $7,350 installed, and most homeowners pay around $5,450 for a gas condensing unit. The numbers below are all-in installed costs — unit, gas hookup, venting, labour, and permit. A like-for-like tankless swap sits lowest; converting off a tank adds new gas-line and venting work plus old-tank removal, which pushes those jobs to the top of the range.
Port Moody is a small market, so most crews sizing a tankless here roll in from Coquitlam or Burnaby, and you want that travel inside the quote rather than tacked on after. In the newer condos along the Evergreen Line the job also needs strata sign-off for the sidewall vent, while older Moody Centre homes bring the usual undersized-gas surprises.

Price by Job Type in Port Moody
| Job | Low | Average | High |
|---|---|---|---|
| Mid-range gas condensing | $4,000 | $5,250 | $6,850 |
| Premium gas condensing (Navien, Rinnai) | $4,500 | $6,100 | $7,900 |
| Converting from a tank (adds gas-line + venting) | $4,750 | $6,300 | $8,400 |
| Electric point-of-use (single fixture) | $350 | $750 | $1,450 |
What's in the Price — and What Isn't
In the price
- The unit itself — a gas condensing model from a name like Navien, Rinnai, or Bosch
- Wall mounting and the bracket
- Gas connection to the existing line
- Venting to the exterior — stainless for non-condensing, PVC or polypropylene for condensing
- A condensate drain on condensing units, plus isolation (service) valves for descaling
- The gas permit and final inspection
- Commissioning: firing the unit, setting flow and temperature, and combustion and CO testing
Costs extra
- Upsizing the gas line or meter if the existing one can't feed the burner (+$500–1,800)
- Electrical work if a new circuit or outlet is needed for ignition and controls (+$200–600)
- Removing and hauling the old tank on a conversion (+$150–300)
- A water softener, which hard-water homes need to protect the heat exchanger (+$1,500–3,000)
- Drywall or finishing if venting or gas runs open up a wall
The number that actually matters in a tankless quote is the heat-exchanger warranty. A 15-year exchanger on a premium unit is worth more than a $200 discount on a 10-year one.

What Moves the Price
- Gas line and meter capacity
- A whole-home unit burns 150,000–199,000 BTU, roughly four times a tank. A ½″ line often has to be upsized to ¾″ and the meter checked — $500–1,800 when it comes up short.
- Venting type
- Condensing units vent through PVC or polypropylene; non-condensing units need stainless. A fresh vent run to an exterior wall adds $400–1,200.
- Electrical for ignition and controls
- Even a gas unit needs power for the igniter, fan, and display. A new circuit or nearby outlet runs $200–600.
- Water hardness
- Hard water scales the heat exchanger quickly. Plan on yearly descaling, and budget $1,500–3,000 if you add a softener to protect the warranty.
- Unit tier
- A builder-grade condensing unit and a premium Navien or Rinnai can differ $800–2,000 before labour — usually in the length of the heat-exchanger warranty.
- Conversion vs tankless swap
- Replacing an existing tankless is mostly labour. Converting from a tank adds gas-line, venting, and removal work — often $1,500–3,000 more.

How the Job Actually Goes
-
Sizing and gas-line assessment
The installer works out your peak flow demand in litres per minute, picks a unit to match, and confirms the gas line and meter can actually feed it. Undersize the gas and the unit throttles; undersize the flow and showers go cold mid-rinse.
Included in the quote
-
Remove the old unit (conversions)
On a switch from a tank, the old unit is drained, disconnected, and hauled away, and the wall is prepped for a mounted heater. A tankless-to-tankless swap skips this step entirely.
Old-tank removal $150–300 when converting
-
Mount and connect
The unit is hung on the wall and tied into gas, water, venting, and — on condensing models — a condensate drain. Isolation valves go on the water lines so future descaling is a quick hookup.
$1,200–2,500 of the labour and materials
-
Commission and test
The gasfitter fires the unit, sets the output temperature and flow, then verifies combustion, checks for CO, and leak-tests every gas joint. This is the step a DIY install can't safely finish.
Included
-
Permit inspection
The gas permit is closed out — through Technical Safety BC in most of the province, or the municipal program in cities that run their own.
Gas permit about $31–$164 by city, more where a municipal plumbing permit also applies
Do It Yourself or Hire a Pro?
Doing it yourself
- A small electric point-of-use unit under a single sink is genuinely DIY — 120V or 240V, no gas, no venting
- You choose the unit and fit it on your own schedule
- A whole-home gas tankless is off-limits: BC law puts gas work in the hands of a licensed gasfitter
- Venting, gas-line sizing, and condensate all have to be right — get one wrong and you either starve the burner or spill combustion gases indoors
- An unpermitted install can void both the manufacturer warranty and your home insurance
- Combustion and CO checks at start-up need instruments most homeowners don't own
Hiring a licensed pro
- Gas sizing, venting, and condensate done to code, with combustion and CO verified at commissioning
- Permit pulled and inspection passed — the paperwork that keeps insurance valid
- The manufacturer warranty stays intact, and you get workmanship coverage on top
- The installer sizes the unit to your real flow demand so you neither over- nor under-buy
- Materials carry the bill — the unit alone can be $1,500–3,000 before labour
- A conversion can run one to two days, not an afternoon
Our take: For a gas tankless there's no DIY path — a licensed gasfitter is the law in BC, and the venting and combustion work is more involved than a straight tank swap. The one exception is a small electric point-of-use heater feeding a single fixture.
Signs It's Time to Replace
- You keep running out of hot water — a big household, back-to-back showers, or a soaker tub outruns a 40-gallon tank
- Your current tank is near the end and you'd rather not be back shopping for another one within a decade
- You want the floor space back — a tankless unit hangs on the wall and frees up the footprint a tank ate
- Your gas bills are high and you're staying in the house long enough for the efficiency to pay back — condensing units run above 90%
- Honest catch: the upfront cost is 2–3× a tank, and hard water means regular descaling to hold the warranty — weigh both before switching
How to Keep the Cost Down
- Don't count on a rebate for a gas tankless — BC's water-heater rebates are for electric heat-pump models, not gas. If you're open to one, as of July 2026 CleanBC Better Homes and BC Hydro each offer up to $1,000 (up to $3,500 income-qualified through CleanBC)
- Right-size the unit to your peak flow — an oversized tankless costs more up front and gains you nothing
- Descale on schedule, yearly in most of BC and more often on hard Interior water — it protects the heat-exchanger warranty and the unit's 20-year life
- Bundle any gas-line upsizing with other gas work — running a fireplace or range line in the same visit spreads the call-out
- Compare the heat-exchanger warranty, not just the sticker price — a longer exchanger warranty is worth more than a small discount
Port Moody Notes: Permits, Homes, Rates
Gas permits route through Technical Safety BC ($116 on a contractor permit, 2026); the City of Port Moody sets a $95 minimum plumbing permit.
The split between glassy transit-oriented condos and century-old Moody Centre cottages means the tankless job swings from a strata-approved vent penetration on one street to a full gas-line upsize on the next.
Tri-Cities rates, same band as Coquitlam.
Questions to Ask Before You Hire
- Are you a licensed gasfitter registered with Technical Safety BC, and does your quote include pulling the gas permit?
- Is gas-line upsizing part of this price, or a change order if my line turns out too small?
- What venting are you running — stainless for a non-condensing unit, or PVC/polypropylene for condensing?
- How long is the heat-exchanger warranty on this unit, and what voids it?
- Do you offer annual descaling, and are service valves installed so a flush is quick?
While the Plumber Is There
Call-out time is a big share of any bill — if one of these applies to your home, pricing it in the same visit usually beats a separate appointment.
Still weighing a tank? A standard replacement is a third of the price up front — worth pricing side by side before you commit to going tankless.
Hard water is what kills tankless heat exchangers. On Interior or valley water, a softener is the difference between a 20-year unit and a warranty fight — cheapest to plumb in during the install.
The hidden cost in most tankless jobs: a high-BTU unit often needs the gas line upsized. Getting the line assessed up front keeps it from becoming a surprise change order.
