Deciding whether to fix an old unit or invest in a new one depends on three primary factors:
- Age: Traditional boilers typically last 15-20 years. If your system has crossed the two-decade mark, parts will become harder to find, and failures are more frequent.
- Cost of Repair (The 50% Rule): If a single repair cost exceeds 50% of the price of a brand-new boiler, replacement is the more financially sound long-term decision.
- Efficiency Gap: Older cast-iron boilers often operate at roughly 60% AFUE (Annual Fuel Utilization Efficiency), meaning 40 cents of every dollar spent on gas is wasted. Modern condensing boilers operate at up to 95% efficiency, paying for themselves through lower monthly bills.
2026 Boiler Replacement Cost Guide for Ontario
Realistic pricing for a professional boiler installation in the GTA generally falls into these tiers:
- $5,000 – $8,000: Standard high-efficiency gas boilers (heat only). Best for homes that already have a separate hot water tank.
- $9,000 – $15,000+: Premium High-Efficiency Combi-Boilers. This price includes the unit, labour, and any required venting/piping upgrades to meet modern high-efficiency standards.
Featured Boiler Systems for Toronto Homes
For Toronto homes looking to maximize space and efficiency, we recommend top-tier Combi-Boilers (such as Rinnai boilers).
These modern “combination” systems are revolutionary because they provide both high-efficiency whole-home heating and on-demand domestic hot water from a single, wall-mounted unit.

Frequently Asked Questions
Q: How much does it cost to replace a boiler in Toronto?
A: Most homeowners spend between $5,000 and $12,000, depending on the complexity of the venting and whether you are switching to a Combi-system.
Q: At what age should a boiler be replaced instead of repaired?
A: If the boiler is over 15 years old and requires a major component (like a heat exchanger or gas valve), we recommend replacement.
Q: What is a combi-boiler and is it good for older Toronto homes?
A: A combi-boiler handles both radiators and your taps/showers. They are excellent for older Toronto homes because they save significant floor space in small basements.
Q: How long does a traditional cast-iron boiler last?
A: With meticulous maintenance, some can last 25-30 years, though they become extremely expensive to operate due to low fuel efficiency.
Q: Why is my radiator or boiler making a loud banging noise?
A: This is often “kettling,” caused by lime-scale buildup or air trapped in the system. It restricts water flow and requires professional servicing to prevent damage to the heat exchanger.
