Oil-to-Gas Burner Conversion Cost Guide for Home Boilers 2026

Typical U.S. homeowners pay $1,200-$8,500 to convert an oil-fired burner to natural gas or propane; the final conversion price depends on burner model, piping, permits, and labor. This article shows typical conversion cost ranges, per-unit pricing, and the main drivers affecting an oil to gas conversion burner cost within common home scenarios.

Item Low Average High Notes
Basic burner conversion kit + install $1,200 $2,500 $4,000 Assumptions: single-family home, existing gas line within 20 ft, standard burner model.
Full burner replacement + piping $2,500 $5,000 $8,500 Assumptions: older boiler, new burner, new gas service to meter.
Permit, plumbing, inspection $200 $600 $1,500 Assumptions: municipal permit fees, minor inspections.

What Homeowners Usually Pay For A Burner Conversion

Most conversions fall into two buckets: a conversion kit (replacing nozzle, controls, and orifice) or a full burner swap with new gas valves and safety controls. Expect a conversion kit plus labor to cost $1,200-$4,000, while a full burner replacement typically runs $2,500-$8,500.

Assumptions: 80–150 MBH residential boiler, accessible boiler room, natural gas available within 20–50 feet.

Breakdown Of Typical Quote Components For Oil-to-Gas Conversion

Contractor quotes commonly list materials, labor, equipment, permits, delivery/disposal, and overhead; understanding each line clarifies the total price.

Materials Labor Equipment Permits Delivery/Disposal Overhead
$300-$2,500 (kits $300-$800; new burners $1,200-$3,000) $400-$2,500 (2-20 hours at $75-$125/hour) $100-$800 (pressure test, hose, crane for large units) $100-$1,500 (local variance) $50-$400 (tank fill/cleanup, oil capture) $200-$800 (markup, diagnostics)

Labor is frequently 30–60% of the final bill when piping or controls require significant work.

How Specific Variables Change The Final Conversion Price

Two strong price drivers are gas service distance and burner output (MBH). For example, running new gas service 0-25 ft adds $200-$800, 25-100 ft adds $800-$3,000, and over 100 ft can exceed $3,000. Larger burners (150+ MBH) increase parts and labor: add $800-$2,500 versus small 60–100 MBH systems.

Numeric thresholds: 60–100 MBH (small), 100–150 MBH (medium), 150+ MBH (large); gas run thresholds: 0–25 ft, 25–100 ft, 100+ ft.

Practical Ways To Reduce Oil-to-Gas Conversion Price

Control scope by choosing a conversion kit instead of full burner replacement when the boiler and heat exchanger are in good condition. Typical savings: $800-$3,000 by opting for a conversion kit and doing preparatory work (clearing access, removing old parts) yourself.

  • Get three written quotes to compare labor hours and line-item prices.
  • Schedule work off-peak (late spring/fall) to avoid rush premiums.
  • Bundle related work (gas line + conversion) for contractor discounts.
  • Retain usable components—reuse gas piping fittings and controls if safe and code-compliant.

Regional Price Differences Across The U.S. For Burner Conversions

Prices vary by region: Northeast and West Coast typically 10–30% above national average; Midwest and South often 5–15% below average. Budget for a +20% premium in high-cost metro areas and -10% in lower-cost rural markets.

Region Typical Range Delta vs. Average
Northeast (urban) $1,800-$8,500 +15% to +30%
Midwest (suburban/rural) $1,200-$5,000 -5% to -15%
South $1,100-$5,500 -5% to +5%
West Coast (urban) $1,600-$8,000 +10% to +25%

Typical Quote Examples With Realistic Specs And Pricing

Three sample quotes illustrate how scope changes price.

Scenario Specs Labor Materials Total
Kit Conversion (Small Home) 80 MBH, gas within 15 ft 3-5 hours @ $85/hr Conversion kit $400 $1,200-$1,800
Full Burner Swap (Older Boiler) 120 MBH, minor piping 8-12 hours @ $95/hr New burner $1,800, valves $300 $3,500-$5,200
Full Replacement + New Gas Service 160 MBH, 60 ft gas run 12-20 hours @ $100/hr Burner $2,500, piping $1,200 $6,000-$8,500

These examples show how labor hours, MBH rating, and gas-run length drive the range between low and high totals.

Permits, Inspections, And Common Add-Ons That Affect Final Price

Permit fees, mandatory pressure tests, oil tank decommissioning, and required safety controls add $200-$1,800. Budget $300-$1,200 for permits and inspections and up to $1,500 more if oil tank removal or remediation is needed.

  • Pressure test and inspection: $100-$400.
  • Oil tank cleanup/decommission: $500-$1,500 (site-dependent).
  • Control upgrades (safety interlocks, new flame sensor): $150-$700.
