What an NTI FTVN 110 replacement usually costs
The FTVN 110 is a wall-mounted, gas-fired condensing boiler in NTI’s FTVN series. The “110” model designation refers to its approximate input capacity in thousands of BTU per hour; it does not mean that every home needs a boiler of this size. A contractor should verify the building’s heat loss and the existing system before quoting a replacement.
For a direct swap with compatible piping and venting, budget about $9,000-$16,000 installed. A middle-of-the-range quote is around $12,500, including the boiler, standard installation labor, basic commissioning, and removal of an existing unit. It generally assumes the home already has a compatible hydronic heating system and that gas, electrical, condensate, and vent connections need only limited adjustment.
Equipment-only prices are less consistent than installed prices because many boilers are sold through plumbing and heating distributors or contractors rather than through a single national retail channel. A quoted $4,000-$7,000 for the boiler may exclude freight, tax, accessories, warranty options, and delivery to the job site. A homeowner should compare quotes on the complete installed scope, not the equipment line alone.
A boiler replacement involving new primary piping, a different vent route, a condensate pump, or multiple zone-control changes can reach $16,000-$27,000. That is not automatically an indication of overcharging: the quote should identify each added task, material, and permit or inspection charge.
How equipment, labor, venting, and removal shape the quote
Installed pricing combines the boiler with the work needed to connect it safely and correctly to the home’s heating, gas, venting, and drainage systems. The ranges below are typical planning figures, not fixed NTI prices; overlap can occur when a contractor bundles labor and materials.
| Quote component | Low | Average | High | Typical scope |
|---|---|---|---|---|
| Boiler and standard accessories | $4,000 | $5,500 | $7,000 | FTVN 110, basic fittings, and common installation materials |
| Installation labor | $2,000 | $3,500 | $5,500 | Removal, connections, setup, and startup |
| Venting and condensate work | $300 | $900 | $2,000 | Standard adjustments through rerouting or added drainage |
| Piping, controls, and electrical | $500 | $1,500 | $4,000 | Minor reconnection through zone or system revisions |
| Removal, disposal, and permit | $200 | $600 | $1,500 | Old-unit handling and local permit or inspection charges |
Ask the contractor to separate the boiler price from installation tasks and allowances. This makes it easier to see whether a higher bid reflects a more expensive unit, extra labor, or work specific to the house. A useful labor estimate can be checked as ; residential HVAC and plumbing labor commonly runs about $75-$150 per hour, with higher rates possible for specialized or emergency work.
Why 110,000 BTU capacity and vent distance change price
The first cost variable is whether a 110,000-BTU-per-hour input boiler fits the home’s actual heat demand. A boiler that is oversized may cycle more often than necessary, while a unit that is too small may not meet design-day heating needs. A contractor should use a heat-loss calculation or other documented sizing method rather than relying only on the old boiler’s label.
Capacity changes can affect both the equipment choice and the labor scope. If the home’s required output is substantially below or above the FTVN 110’s capacity, another model may be more appropriate. The price comparison should include the proposed boiler model, capacity, and included controls, not just the brand name.
Venting distance and route also matter. A short, accessible route using approved materials may add only a few hundred dollars, while a longer route, roof termination, or difficult wall penetration can add roughly $500-$2,000 or more. The allowable vent length and configuration depend on the exact boiler instructions and fittings; the installer should verify those limits rather than assume a generic maximum.
System condition can create larger differences. Corroded near-boiler piping, a failed circulator, a leaking expansion tank, or zones that need rebalancing may add $300-$2,500 for common repairs, with extensive piping replacement costing more. A quote should distinguish repairs needed for safe operation from optional upgrades.
Fuel and water conditions are additional checks. A gas-line capacity issue, inadequate electrical service, or a condensate drain with no suitable nearby route can require extra work. Hard water and system debris may also make cleaning or flushing appropriate. These items should be quoted after inspection, not listed as unexplained contingencies.
How many labor hours does an FTVN 110 installation take?
A straightforward one-for-one replacement often takes one crew about 8-14 labor hours, frequently completed in one working day. The calendar duration can be longer if a permit inspection, special-order parts, vent changes, or a second visit for system balancing is needed. Contractors may quote a fixed project price rather than disclose every hour.
Expect the labor bill to rise when the job changes from replacement to system rework. Adding or relocating pumps, changing several zone valves, replacing a long vent run, or correcting an inaccessible condensate route may add 4-12 hours or more. At $75-$150 per hour, that range represents roughly $300-$1,800 in direct labor before materials, overhead, and any subcontractor charges.
Installation generally includes disconnecting and removing the old boiler, setting and mounting the new unit, adapting the water and gas connections, connecting approved venting and condensate drainage, wiring controls, filling and purging the system, and testing operation. Startup should include checks required by NTI’s installation instructions and local code. Ask whether the quote includes a written commissioning record and homeowner handoff.
Urgent no-heat work can cost more than a scheduled replacement. After-hours response, temporary heat, or a rush installation may add approximately $300-$1,500, depending on timing and local availability. If the existing boiler can safely operate until a planned replacement date, comparing scheduled bids may avoid rush charges.
How Northeast and Midwest labor markets affect installed price
Location can shift an otherwise similar boiler replacement by roughly 10%-25%. Dense Northeast markets and high-cost West Coast cities may land near the upper end because of higher labor rates, parking or access constraints, and stricter permit requirements. Rural areas may have lower hourly rates but higher travel, delivery, or scheduling charges.
Use the local quote as the meaningful benchmark, not an online equipment listing alone. A $12,000 project in one market may buy a direct replacement with basic controls, while the same budget elsewhere may not cover a difficult vent reroute or extensive code work. Taxes, distributor freight, and local inspection fees also vary.
For a typical direct replacement, a broad planning range is $9,000-$14,000 in lower-cost markets, $10,000-$16,000 in many suburban markets, and $12,000-$19,000 in higher-cost urban areas. These ranges assume similar equipment and basic scope. They are not regional price guarantees, and a major piping or venting project can exceed them anywhere.
When comparing bids, request the same details from each contractor: exact boiler model, vent and condensate work, removal, permit allowance, controls, startup, and warranty terms. That helps separate true regional labor differences from quotes that include different work.
How replacement scope compares with repair or a different boiler
Repair can cost less when the FTVN 110 or another existing boiler has a single replaceable fault and the unit is otherwise in sound condition. Common service calls may run $150-$400 for diagnosis or basic maintenance; repairs involving an igniter, sensor, pump, or control part may total $250-$1,500, depending on parts and labor. A heat exchanger or major control failure can be more expensive and should be compared with replacement.
Compare the repair quote with the remaining condition of the whole heating system. A low-cost repair may make sense if the boiler is relatively new and the repair restores reliable operation. If a unit has repeated breakdowns, corrosion, or multiple failing parts, paying for one more repair may not be the lowest-cost choice over the next several winters.
A different boiler model can be a reasonable alternative if a load calculation shows the FTVN 110 is not the right size or if another model better matches venting and control requirements. Comparable high-efficiency wall-mounted condensing boilers may have equipment prices of about $3,500-$8,000 and installed prices of roughly $8,500-$18,000 for standard replacements. Brand, capacity, included accessories, and contractor availability drive the spread.
Do not compare equipment prices without checking what is included. One bid may include a new circulator, air separator, dirt filter, and system flush; another may reuse existing components. Ask which items are required for a dependable installation and which are optional improvements.
Three FTVN 110 quotes for different home conditions
These examples show how project scope can produce different totals for the same boiler. They assume ordinary U.S. residential labor and are illustrations, not manufacturer-set prices or guaranteed local bids.
| Project | Work and labor | Estimated total | Why the price differs |
|---|---|---|---|
| Direct basement replacement | Boiler at $5,000; 10 labor hours; minor vent and condensate adjustments | $10,000-$12,500 | Existing piping and controls remain serviceable |
| Suburban system refresh | Boiler at $5,500; 14-18 labor hours; new near-boiler fittings and cleanup | $13,000-$17,000 | Includes additional piping, testing, and a permit allowance |
| Urban vent and zone rework | Boiler at $6,500; 20-28 labor hours; longer vent route and control changes | $18,000-$25,000 | Higher labor rates and more extensive system adaptation |
The lowest quote is not necessarily the lowest complete project cost. Check whether each example or bid includes the same removal, vent termination, condensate treatment, zone controls, commissioning, permit, and warranty coverage. A missing item can become an added charge after work begins.
Which installation choices can lower an FTVN 110 bill?
Keeping the project scope focused is usually more effective than selecting the cheapest boiler listing. If existing venting, piping, pumps, and controls are compatible and in good condition, ask the contractor to identify which parts can safely remain. Avoid authorizing a broad system replacement without an explanation of the condition or code issue requiring it.
Get at least two or three written, itemized quotes using the same model and scope. Ask contractors to list the FTVN 110 model, equipment and accessory costs, labor, removal, permit, venting, startup, and any excluded work. For a quote that is substantially above others, request a written explanation of the added tasks rather than negotiating from an equipment-only price.
Schedule replacement before an emergency if the existing boiler is near the end of its service life and showing recurring problems. Planned work allows time to compare availability and avoid after-hours premiums. It may also help avoid a cold-weather scheduling backlog, although seasonal discounts and contractor schedules vary by market.
Do the simple preparation that the installer requests: clear access to the boiler and mechanical room, move stored items, and identify where the old unit and nearby shutoffs are located. Do not disconnect gas, water, wiring, venting, or safety controls. Any homeowner work should be limited to safe access and cleanup, leaving technical tasks to a qualified professional.
Finally, evaluate upgrades by their documented benefit and cost. A new control, pump, or water-treatment device may be useful when the existing system requires it, but it should not be added automatically. Request separate prices so the buyer can distinguish required installation work from optional improvements.
