What's Included in the Installation Price

When you get a quote for combi boiler installation, make sure it includes everything. Some contractors quote a low price but exclude permits, gas work, or system flushing — then surprise you with extra charges. Here's what a complete installation should include:

• New combi boiler unit (all manufacturers require authorized dealer purchase for warranty)
• Removal and disposal of old boiler and hot water tank
• Gas line connection and gas pressure testing
• New venting — typically concentric PVC through wall or roof
• Condensate drain line to floor drain or sump pump
• System power flush to remove sludge before installing new boiler
• New magnetic filter (e.g., Fernox TF1 or similar)
• System inhibitor dosing after flush
• Building permit ($150–$300 depending on municipality)
• City of Vancouver / municipal gas inspection fee
• Startup, commissioning, and combustion analysis
• Manufacturer warranty registration
• 1-year labor warranty (standard)

Installation vs Replacement Cost

The distinction between a new installation and a replacement matters for pricing:

• Replacement (swap old boiler for new combi): $6,500 – $14,000 — assumes existing gas line, venting route, and adequate gas meter capacity
• New installation (no boiler previously): $9,000 – $18,000 — requires new gas line from meter, new venting through wall/roof, new condensate drain, and possibly a gas meter upgrade if current meter is undersized
• Boiler + hot water tank replacement with combi: $7,000 – $12,000 — removes the tank and boiler, installs one combi unit. Most common Vancouver scenario
• High-rise condo replacement: $5,500 – $9,000 — simpler due to existing venting common stack and standard gas pressure. Strata approval may be required
• Heritage home conversion (Vancouver Special, Kitsilano character home): $9,000 – $16,000 — often requires new gas line, complex venting routes, and system configuration changes

Additional Costs to Budget For

These items may or may not be included in your quote — always ask:

• Gas meter upgrade (if current meter is undersized): $500 – $1,200 (FortisBC handles this)
• New thermostat (smart thermostat like Nest or Bosch EasyControl): $200 – $400
• Radiator TRV replacement (if existing TRVs are seized): $35 – $80 per radiator
• Asbestos abatement (if your 1970s-era boiler room has asbestos insulation): $500 – $3,000+
• Water softener or scale protection (if you have hard water): $500 – $1,200
• Outdoor reset sensor (improves efficiency 5-10%): $150 – $300
• Extended labor warranty (beyond 1 year): $200 – $500 per additional year

How Rebates Reduce Your Cost

FortisBC and CleanBC offer rebates for high-efficiency combi boiler installations. In 2026, qualifying installations can receive $1,000 to $3,000 in combined rebates — effectively reducing your installation cost by 10-25%.

Rebates are not automatic. They require pre-approval in some cases, specific efficiency ratings (typically ≥95% AFUE), professional installation by a licensed gas fitter, and post-installation inspection. We handle all rebate paperwork for our customers.
