A Harman PB105 pellet boiler typically costs about $5,000-$9,000 for the boiler itself when available, while a complete installed system can run roughly $10,000-$20,000. The final price depends on whether the unit is new, used, or refurbished, plus venting, hydronic connections, storage, delivery, and local labor.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| PB105 boiler only | $5,000 | $7,000 | $9,000 | Availability and condition affect price |
| Installed boiler, basic tie-in | $10,000 | $14,500 | $20,000 | Existing compatible hydronic system assumed |
| Used or refurbished unit | $2,500 | $4,500 | $7,000 | Condition, testing, and included parts vary |
| Annual pellet fuel | $1,200 | $2,000 | $3,200 | Approximate household range; weather and usage matter |
What a Harman PB105 costs for a typical home
A buyer should budget around $5,000-$9,000 for a new or dealer-supplied PB105 boiler, if one is available, and approximately $10,000-$20,000 for equipment and professional installation. The middle of that installed range is about $14,500 for a straightforward replacement that can use existing hydronic piping and has ordinary access.
The installed figure is not the boiler price alone. A complete project may include freight, a code-compliant exhaust vent, water-side piping, controls, electrical work, commissioning, and removal of an existing appliance. A new installation with a pellet storage system or extensive plumbing changes can exceed $20,000.
PB105 pricing can be less predictable than pricing for a current mass-market boiler because the model may be sold through limited dealer or remaining-stock channels. A listing price does not establish that the unit is new, warrantied, complete, or suitable for the home. Buyers should compare the exact model, condition, serial information, included controls, and warranty in writing.
Assumptions: U.S. pricing, standard residential hydronic connection, average access, and no major chimney or electrical upgrade.
How boiler, venting, and labor shape the quote
Contractor estimates commonly divide into equipment, installation labor, venting and materials, and removal or commissioning. The ranges below are planning figures, not a fixed manufacturer price; a difficult retrofit or a higher-cost metro area may exceed them.
| Quote item | Low | Average | High | Typical scope |
|---|---|---|---|---|
| PB105 boiler | $5,000 | $7,000 | $9,000 | Unit price; condition and stock affect quote |
| Installation labor | $2,000 | $3,500 | $6,000 | About 25-50 crew hours at blended rates |
| Venting and fittings | $700 | $1,500 | $3,000 | Vent pipe, termination, adapters, and seals |
| Hydronic parts and controls | $500 | $1,500 | $3,500 | Valves, pumps, wiring, and piping changes |
| Delivery, removal, commissioning | $300 | $1,000 | $2,000 | Freight, old-unit handling, startup checks |
Labor rates for boiler and hydronic work often fall around $75-$150 per technician-hour, with higher rates possible for specialized service or urgent work. Estimates may show labor as a project total rather than an hourly charge.
Ask whether the quote includes startup and system testing. A low equipment quote may omit delivery, vent components, electrical connections, controls, or the labor needed to verify safe operation. Request an itemized scope so competing bids cover comparable work.
Which home size, vent route, and system changes raise the price
Heat demand matters more than floor area alone. Insulation, air leakage, local winter temperatures, ceiling height, and hot-water demand all affect sizing. A contractor should calculate the building’s heat loss rather than assume a boiler output from square footage; an oversized boiler can add cost without improving comfort.
Venting is a major price variable. A short, accessible route through an exterior wall may keep vent materials and labor near $700-$1,500. A long route, several offsets, a difficult roof termination, or a code-driven reroute can push that work toward $2,000-$3,000 or more. Ask the installer to specify route length and included components.
Existing hydronic compatibility also changes the estimate. Reusing sound supply and return piping may keep added parts near $500-$1,500. Replacing circulators, adding zone controls, correcting undersized piping, or modifying a buffer tank can bring hydronic work to $2,000-$3,500 or higher.
Fuel handling has its own scale. A small hopper suited to frequent manual loading costs less than adding bulk storage, an auger, or a delivery arrangement. If the project needs a dedicated pellet room or substantial material handling, the added expense can run from several hundred dollars to several thousand, depending on storage volume and building work.
Confirm the boiler’s rated output against a heat-loss calculation and the existing system’s water temperature. This can prevent paying for unnecessary capacity or discovering after purchase that piping, emitters, or controls need more extensive changes.
Planning thresholds: vent routes longer than about 10-15 feet, multiple direction changes, or hydronic changes involving several zones commonly require additional labor and materials.
Ways to trim the PB105 installation price without cutting safety
Keep the project scope focused on required work. If the existing piping, circulators, electrical supply, and vent route are serviceable and code-compliant, ask the installer to price reuse separately from optional replacement. Do not accept an assumption that every old component must be replaced, but do not retain equipment that fails inspection or is incompatible.
Compare at least two itemized quotes with the same assumptions: boiler condition, freight, vent route, removal, controls, startup, warranty, and permit handling. A $1,000 difference can reflect omitted work rather than a better deal. Ask each contractor to identify exclusions and any allowance that could change after opening the work area.
Choose storage and automation to match actual use. A basic arrangement may avoid the upfront cost of large bulk storage or added feed equipment, while a household using the boiler heavily may value fewer refills. Compare the installed cost of each option with the expected loading effort and fuel-delivery arrangements.
Spend first on correct sizing, safe venting, and proper commissioning. Avoid paying extra for unneeded controls or cosmetic changes, but do not reduce cost by skipping required clearances, permits, inspections, or system testing.
How many labor hours does a PB105 replacement take
A direct replacement in a prepared mechanical room may take a two-person crew about 1-2 working days, or roughly 16-32 combined labor hours. A more involved installation with new venting, multiple hydronic alterations, or equipment removal can require 3-5 days and approximately 40-80 combined labor hours, especially when separate trades are scheduled.
These ranges describe combined crew time, not elapsed time from signing a contract to heat being restored. Delivery delays, permit review, inspection scheduling, and coordination with an electrician or plumber can extend the calendar schedule. A contractor may also charge a minimum service or mobilization fee, commonly $150-$400, for smaller follow-up visits.
Ask whether the labor price includes draining and refilling the hydronic system, air purging, control setup, combustion or operating checks, and homeowner instruction. Clarify how return visits are billed if an inspection requires corrections or a part is missing.
A written schedule should identify the workday estimate and what could extend it. A quote that lists only “installation” makes it difficult to compare labor coverage or determine whether commissioning is included.
How regional labor rates shift installed boiler prices
Installed costs often run 10%-25% above the national middle in high-cost metro areas and parts of the Northeast, where skilled hydronic labor, travel, and permitting can be more expensive. In lower-cost rural or Midwestern markets, a straightforward job may land 5%-15% below the national middle, though fewer qualified pellet-boiler contractors can reduce that advantage.
Local fuel access also affects the full budget. Areas with established pellet delivery may offer more convenient bulk supply, while remote locations can face higher delivery charges or fewer providers. Freight for a heavy boiler can also vary according to distance, unloading needs, and whether the seller offers curbside or inside delivery.
These regional percentages are broad comparisons, not adjustments to apply mechanically. A city quote can be lower if the venting and piping are simple, while a rural project can be expensive if the crew must travel, transport equipment, or return for inspection. Compare local quotes that describe the same job rather than relying only on national averages.
Use regional ranges as a reasonableness check, not as a substitute for site-specific bids. Request separate charges for travel, freight, permits, and specialty subcontractors to see where location is affecting the price.
What delivery, permits, and pellet storage add to the budget
Delivery may be included in a dealer’s equipment price or charged separately. For a heavy boiler, allow roughly $200-$800 for ordinary freight and handling; remote delivery, lift-gate service, stairs, or moving the unit into a basement can add more. Confirm who unloads it and who is responsible if the unit arrives damaged.
Permit and inspection charges vary by municipality. A basic mechanical permit may cost about $50-$300, while a project involving electrical work or multiple inspections may bring combined fees to $100-$600 or more. The installer should identify which permits apply and whether fees are included in the estimate.
Pellet storage can range from a few hundred dollars for basic bins and handling supplies to $1,000-$4,000 or more for larger storage arrangements, delivery hardware, and related installation. The right amount depends on available space, fuel consumption, delivery options, and how often the household is willing to refill.
Get delivery, permit, and storage charges listed as separate quote lines. This makes it easier to distinguish the boiler’s price from site-specific expenses and avoids surprises on installation day.
When repair or a used PB105 makes more financial sense
A used PB105 may be listed around $2,500-$7,000, but the asking price is only part of its cost. Add transport, inspection, replacement wear parts, controls, and installation, and a used unit can approach the cost of a dealer-supplied boiler without receiving the same warranty. Have a qualified technician inspect its condition and confirm parts availability before purchase.
For a functioning boiler with a specific failed component, diagnosis and repair may cost about $250-$1,200, including common service labor and parts. More extensive repairs involving major assemblies, feed mechanisms, or control components can reach $1,500-$3,000. The exact cost depends on the failure, parts availability, and the contractor’s service rate.
Compare the repair estimate with the installed replacement quote, not just the price of a new boiler. Consider the age and condition of the venting, pumps, controls, and hydronic piping. If several components need work or the unit has a history of repeated faults, replacement may offer more predictable operating costs; a single isolated failure on a well-maintained unit may justify repair.
Before buying used, verify operation, completeness, ownership, and warranty in writing. A price that looks low can become expensive if the boiler cannot be tested, essential parts are missing, or no local technician will install or service it.
