Cost Breakdown in Rhode Island

Typical Installed Costs

In Rhode Island, most homeowners spend between $7,500 and $25,000 for a new boiler, including installation. Smaller homes can be on the low end, while large or complex projects run higher.

Labor costs in Rhode Island average $75–$200 per hour, which makes installation a major part of the total bill.

Example Scenario Costs

• Small home (1,000–1,500 sq ft): $5,500–$7,000
• Medium home (1,500–2,500 sq ft): $7,000–$9,000
• Large home (2,500+ sq ft): $9,000–$11,000+

These examples assume a standard replacement, without major structural upgrades.

Key Factors That Affect Boiler Replacement Cost

The price you’ll pay depends on several important factors:

• Boiler size and BTU output. Larger homes need more capacity.
• Efficiency rating. High-efficiency condensing boilers cost more upfront.
• Brand and model. Premium brands raise costs but often last longer.
• Labor rates. Rhode Island averages are higher than some states.
• Permits and requirements. Local codes may require venting upgrades or new gas lines.

Each of these elements influences the final number you’ll see on a quote.

Removing the Old Boiler During Replacement

Many homeowners forget to factor in the cost of removing the old boiler.

In Rhode Island, removal and disposal usually add $500–$2,000 to the total project, depending on the boiler’s size, location, and accessibility.

For example, removing a basement boiler with tight stairs can take much longer than replacing one in a ground-level utility room.

Always confirm with your installer whether old boiler removal is included in the quote.

Types of Gas Boilers & Their Cost Ranges

Different boiler styles come with different price tags:

• Conventional boilers: $7,500–$12,000 installed
• System boilers: $7,500–$9,000 installed
• Combination (combi) boilers: $7,000–$9,500 installed
• High-efficiency condensing boilers: $15,000–$25,000+ installed

High-efficiency boilers cost more initially, but their 90%+ AFUE ratings cut heating bills over time.

How to Save Money & Incentives in Rhode Island

Rhode Island homeowners can reduce upfront costs through state and utility rebates. For example, National Grid has offered rebates up to $2,400 for qualifying high-efficiency boilers.

Other ways to save:

• Get multiple quotes before deciding.
• Schedule installation in spring or summer, when demand is lower.
• Weigh upfront cost vs lifetime fuel savings.

Efficiency often pays off within a few years through reduced heating bills.

Choosing the Right Installer

The installer you choose impacts both cost and long-term reliability.

Look for:

• Licensed and insured contractors
  Transparent, written quotes
• Clear warranties on both equipment and labor
• Local references from Rhode Island customers

A good installer will also explain whether your gas line, venting, or radiators need upgrades. This prevents unpleasant surprises during the job.
