Price of Replacing 10 ton Steam Boiler

Cost to replace a 10-ton steam boiler – from $52,000 for a basic replacement to over $130,000 for a high-efficiency or complex installation. Get a detailed breakdown of equipment, removal, installation, permits, and expert money-saving tips.

1. Boiler Unit Cost

The base price of a new 10-ton steam boiler varies with fuel type, manufacturer, and efficiency level:

• Standard‐efficiency models typically range from $52 000 to $96 000.

• High-efficiency or specialty units (e.g., low-NOₓ, condensing designs) can push that figure toward $70 000–$130 000 or more.

2. Removal of the Old Boiler

Before installing the new system, your existing boiler must be safely taken out and disposed:

• Larger commercial units can cost $500–$2 000 to dismantle and haul away.

• Access challenges (e.g., tight boiler rooms, crane requirements) may add further labor or equipment rental charges.

3. Installation & Piping Labor

Labor is often the single largest expense after the boiler unit itself:

• Basic installation labor for a 10-ton steam boiler typically falls between $1 500 and $3 000.

• Complex piping and controls—including header work, pressuretrols, safety valves, and interconnecting piping—can multiply labor costs. In many commercial/industrial jobs, total labor (mechanical, electrical, control wiring) may approach 50% the boiler’s retail price, especially if extensive system upgrades are included.

4. Permits, Inspections & Ancillary Equipment

Local jurisdiction requirements can add:

• Permitting and inspection fees: $50–$300 depending on municipality.

• Chimney liners, condensate neutralizers, or gas-line tie-ins can each cost $200–$1 500 extra.

• Controls upgrade (digital boilers controls, BMS integration): $1 000–$5 000 if required.

6. Key Cost Drivers & Savings Tips

• Fuel Type: Natural gas boilers tend to be cheaper than oil or electric units.

• Efficiency Upgrades: Condensing and modulation controls add upfront cost but deliver 10–20% fuel savings over time.

• Bundling Work: Scheduling pipe, valve, and insulation upgrades simultaneously can reduce repeat mobilization charges.

Replacing a 10-ton steam boiler is a significant investment, but careful specification, competitive bidding, and scope management can help you hit your budget while ensuring safety and long-term performance.
