The Lennox GWM Ie boiler price varies by unit size, installation complexity, and region; buyers typically pay $3,500-$8,000 for the unit and $6,500-$16,000 installed. This article lists typical pricing, the major cost components, and concrete ways to estimate and reduce final expense for a gas-fired wall-mount condensing boiler.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Unit Only (GWM Ie) | $3,500 | $5,500 | $8,000 | Assumptions: 80–120 MBH units, standard controls. |
| Installed (Residential Retrofit) | $6,500 | $10,500 | $16,000 | Assumptions: 1–2 zone house, 2–6 hours venting work. |
| Upgrades (New Venting/New Controls) | $1,200 | $2,800 | $5,000 | Assumptions: chase work, PVC venting, new thermostat wiring. |
What Buyers Usually Pay For A Lennox GWM Ie Boiler
Typical market pricing for a Lennox GWM Ie: unit price $3,500-$8,000; installed price $6,500-$16,000 depending on job scope and region. Average residential replacement, including basic piping and hookup, runs about $10,500.
Assumptions: Midwest labor rates, single-family home, 80–120 MBH unit, existing gas line within 5 feet.
Breakdown Of A Lennox GWM Ie Quote By Cost Component
A representative quote separates line items into materials, labor, equipment, permits, delivery/disposal, and warranty; expect different percentages depending on retrofit difficulty. Labor and materials typically make up 70%-85% of the installed price.
| Materials | Labor | Equipment | Permits | Delivery/Disposal | Warranty |
|---|---|---|---|---|---|
| $2,000-$5,500 (boiler, controls, fittings) | $1,800-$6,000 (installation labor) | $200-$900 (vents, pumps) | $50-$600 (local permit fees) | $100-$600 (old boiler removal) | $0-$700 (extended warranty) |
How System Size And MBH Rating Affect The GWM Ie Price
Unit selection is MBH-based: smaller homes use 40–80 MBH, medium homes 80–120 MBH, larger homes 120–180+ MBH; price rises with capacity. Expect unit cost to increase roughly $25-$60 per MBH as capacity grows.
Examples: a 60 MBH unit may cost $3,500-$4,500; a 120 MBH unit $5,000-$7,000; jobs above 150 MBH often need different venting and can push installed totals past $14,000.
How Venting, Combustion Air, And Physical Access Change The Final Quote
Venting upgrades and access add significant cost: PVC direct venting vs. stainless chimneys, chase modifications, and long vent runs. Replacing a masonry chimney or installing long PVC runs can increase costs by $1,200-$4,000.
Other variables: chase length over 25 feet adds material and labor; confined-space combustion air work or code-required mechanical ventilation increases time and fees.
Practical Ways To Reduce Lennox GWM Ie Boiler Price
Cost control options include replacing only the boiler module while keeping serviceable pumps, scheduling work in off-peak seasons, and providing easy access to the utility area. Obtaining 3 competitive quotes and avoiding unnecessary control upgrades typically saves 8%-18% on total price.
- Keep existing piping and pumps if compatible and in good condition.
- Bundle related work (gas line, controls) with the same contractor to reduce mobilization fees.
- Time the replacement for spring or fall to avoid peak heating-season premiums.
Regional Price Differences For Unit And Installation
Installed prices vary: Northeast and West Coast are about 10%-25% higher than the national average; Midwest and South are typically 5%-15% lower. A $10,500 average installed job could be $12,000-$13,000 in a high-cost metro or $8,500-$9,500 in a lower-cost area.
Assumptions: similar job scope, same MBH size, comparable material choices.
Typical Add-Ons, Removal Fees, And Real-World Quote Examples
Common add-ons: new gas piping ($300-$1,200), condensate neutralizer ($100-$350), secondary pump ($250-$900), control panel upgrade ($400-$1,200). Removal and disposal of the old boiler usually costs $100-$600.
| Example | Specs | Labor Hours | Price |
|---|---|---|---|
| Basic Replacement | 80 MBH, reuse pumps, short vent | 8-12 hours | $6,500-$8,500 |
| Standard Install | 100 MBH, new PVC vent, new controls | 12-20 hours | $9,500-$12,500 |
| Complex Retrofit | 120+ MBH, chimney work, new gas line | 20-40 hours | $13,000-$18,000+ |
