The Short Answer
Replacing a hot water tank in BC’s Lower Mainland typically costs $1,500 to $3,500 installed in 2026, before GST.
- Like-for-like 40 or 50 gallon gas tank: about $1,500 - $2,500
- Power-vent gas tank: about $2,500 - $3,500
- Standard electric tank: about $1,500 - $2,500
- Heat pump water heater: about $3,500 - $6,000 before rebates
The tank itself is usually under half the bill. Labour, venting, the gas or electrical connection, code-required parts, permits and disposal make up the rest.
Cost by Tank Type and Size
| Tank | Typical installed cost (Lower Mainland, 2026) | Notes |
|---|---|---|
| 40 gal gas, atmospheric vent | $1,500 - $2,200 | Most common like-for-like replacement |
| 50 gal gas, atmospheric vent | $1,700 - $2,500 | Families, 2+ bathrooms |
| 40-50 gal gas, power-vent | $2,500 - $3,500 | Vents through a side wall with a fan; needs power |
| 40 gal electric | $1,500 - $2,000 | Simple install where there’s no gas |
| 50-60 gal electric | $1,700 - $2,500 | Larger households without gas |
| 50-65 gal heat pump water heater | $3,500 - $6,000 | Most efficient; rebate-eligible |
Atmospheric vs power-vent: a standard (atmospheric) gas tank vents straight up through a metal flue into a chimney or B-vent. A power-vent tank uses a fan to push exhaust out through PVC pipe in a side wall. Power-vent costs more and needs an outlet, but it’s the solution when there’s no usable chimney. That’s common when a furnace has been upgraded and left the water heater “orphaned” in an oversized chimney.
What Should Be in the Quote
A complete hot water tank replacement includes:
- The new tank and removal and disposal of the old one
- Gas connection (with a new shut-off and sediment trap) or electrical connection
- Venting: reconnecting to the existing flue, or new venting if required
- A new temperature and pressure (T&P) relief valve and discharge pipe
- Seismic restraint straps, required for water heaters in BC
- A thermal expansion tank where required (common in homes with a backflow preventer or check valve on the water service)
- Gas and/or plumbing permit as required by your municipality
- Start-up, burner check and a CO / venting safety check
Common add-ons that raise the price:
| Add-on | Typical cost |
|---|---|
| Expansion tank (if not already present) | $150 - $350 |
| Drain pan with drain line (finished spaces, upper floors) | $100 - $250 |
| Chimney liner or venting change for an orphaned water heater | $500 - $1,500 |
| Converting to power-vent (new PVC venting + outlet) | $600 - $1,200 |
| Gas line re-routing or upsizing | $300 - $1,000 |
| Difficult access (tight closets, crawlspaces, stairs) | $150 - $500 |
40 vs. 50 Gallon: Which Size?
| Household | Bathrooms | Suggested gas tank | Suggested electric tank |
|---|---|---|---|
| 1-2 people | 1 | 40 gal | 40 gal |
| 2-3 people | 1-2 | 40 gal | 50 gal |
| 3-4 people | 2 | 40-50 gal | 50-60 gal |
| 4-5+ people | 2-3 | 50 gal (or tankless) | 60+ gal or heat pump |
Check the first-hour rating, printed on the yellow EnerGuide label: how many gallons of hot water the tank can deliver in an hour starting full. Gas tanks recover faster than electric ones, so a 40 gallon gas tank often keeps up with a household that would need a 50-60 gallon electric tank. If you regularly run out with a 50 gallon tank, a tankless water heater may be a better fit than going bigger.
Running Costs: Gas vs Electric vs Heat Pump
For a typical Lower Mainland family using about 60 gallons of hot water a day, at mid-2026 FortisBC and BC Hydro rates:
| Water heater | Approx. efficiency (UEF) | Annual energy cost |
|---|---|---|
| Standard electric tank | ~0.93 | ~$600 |
| Standard gas tank | ~0.62 | ~$290 |
| Condensing / high-efficiency gas tank | ~0.80 | ~$230 |
| Heat pump water heater | ~3.3+ | ~$170 |
Estimates use about $12.60/GJ in FortisBC variable gas charges and BC Hydro’s 14.08¢/kWh Step 2 rate. Your costs depend on usage and incoming water temperature.
Heat pump water heaters pull heat from the surrounding air, so they work best in a garage, basement or utility room with some space around them. They cool and dehumidify that space slightly as they run. They also qualify for rebates, which can narrow or close the upfront price gap.
Rebates for Water Heaters in BC
- Gas water heaters (income-qualified): starting Oct. 15, 2026, FortisBC is re-introducing a $2,500 water heater rebate for income-qualified natural gas customers. Check FortisBC’s rebates page for qualifying models.
- Standard gas or electric tanks: no current CleanBC or BC Hydro rebates.
- Heat pump water heaters: CleanBC’s income-qualified Energy Savings Program offers up to $3,500 for a qualifying heat pump water heater. If it replaces a gas tank, the gas water heating equipment must be removed or decommissioned. BC Hydro has also offered a $1,000 rebate for replacing an electric tank with a heat pump water heater. Units must be on the program’s qualified product list.
Rebate rules and amounts change during the year. Check Better Homes BC before you buy.
Repair or Replace?
Tanks typically last 8-12 years. Replace rather than repair when:
- The tank itself is leaking from the body or bottom. A tank leak can’t be repaired.
- There’s rust in the hot water or around the base
- It’s over 10 years old and needs a significant repair
- You hear rumbling or popping that flushing doesn’t fix (heavy sediment)
Repairs like a failed thermocouple, gas control valve, igniter or heating element can be worthwhile on a tank under about 6-8 years old. Our guide to how long a hot water tank lasts covers the warning signs in more detail.
Hot Water Tank Replacement in Richmond, White Rock and Across the Lower Mainland
Richmond: garages, closets and power-vent. Most of Richmond sits on the Fraser River delta with a high water table, so few homes have basements. Water heaters usually live in a garage, a ground-floor utility closet or a townhome mechanical cupboard. In tight closets and townhomes without a usable chimney, power-vent tanks are common, which puts many Richmond replacements in the $2,200 to $3,500 range. Garage installs need protection from vehicle impact, and closet installs in finished spaces should get a drain pan. Strata townhome complexes may also have rules about vent locations and preferred contractors.
White Rock and South Surrey: hillside homes and salt air. Homes on the White Rock hillside often have the water heater on a lower level with long vent runs, and older homes may share a chimney with the furnace. Near the waterfront, salt air shortens the life of exterior vent terminations and outdoor fittings. A typical White Rock like-for-like gas replacement lands around $1,600 to $2,500. Venting changes push it higher.
Coquitlam, Maple Ridge and Burnaby: basement installs. Older homes here usually have the tank in an unfinished basement next to the furnace, so like-for-like replacements are straightforward. Watch for an orphaned water heater if the furnace was upgraded to a PVC-vented high-efficiency model. The water heater then needs a chimney liner or a power-vent tank.
Bottom Line
Budget $1,500 to $3,500 to replace a hot water tank in the Lower Mainland. A like-for-like 40 or 50 gallon gas tank lands near the low end, and power-vent and code-driven venting work push toward the top. Gas tanks are cheaper to run than electric. Heat pump water heaters cost more upfront but are the cheapest to run and the only tank type with rebates.

Frequently Asked Questions
Most Lower Mainland hot water tank replacements cost $1,500 to $3,500 installed in 2026, before GST. A like-for-like 40 or 50 gallon gas tank typically costs $1,500 to $2,500. Power-vent gas tanks run about $2,500 to $3,500, and jobs that need venting, gas line or code upgrades cost more. Heat pump water heaters typically cost $3,500 to $6,000 before rebates.
A 40 gallon tank usually suits 1 to 3 people with one or two bathrooms. A 50 gallon tank suits 3 to 5 people, two or more bathrooms, or a household with a large soaker tub. Compare the first-hour rating on the label rather than tank size alone; a gas tank with a strong burner can outperform a larger electric tank.
Gas is cheaper to run. At 2026 FortisBC and BC Hydro rates, a typical family spends roughly $290 a year heating water with a standard gas tank versus about $600 with a standard electric tank. A heat pump water heater is the cheapest of all at roughly $170 a year, and it qualifies for rebates.
A standard hot water tank typically lasts 8 to 12 years. Lifespan depends on water quality, maintenance (flushing sediment and checking the anode rod) and how hard the tank works. Tanks over 10 years old that show rust, leaking, rumbling or inconsistent hot water are usually due for replacement.
A complete quote includes the new tank, removal and disposal of the old one, connection to the gas or electrical supply, venting, the temperature and pressure relief valve and discharge pipe, seismic straps, any required expansion tank, permits and start-up testing. Ask for anything extra, like venting changes or a drain pan, to be itemized.
Starting Oct. 15, 2026, FortisBC is re-introducing a $2,500 water heater rebate for income-qualified natural gas customers; check FortisBC's program details for qualifying models.
