A Paloma tankless water heater typically costs about $900-$2,200 for the unit when available, while a professionally installed replacement commonly totals $2,000-$5,000. Final price depends on model availability, fuel type, venting, gas-line capacity, local labor rates, and whether the job is a straightforward swap or a new installation.

Assumptions: U.S. prices in USD for a residential gas unit, standard access, and ordinary materials; local quotes and model availability can differ.
What a Paloma tankless heater costs to buy and install
For a residential gas Paloma tankless heater, a reasonable equipment budget is $900-$2,200 if a suitable unit is in stock through a legitimate seller. Because Paloma-branded products may be difficult to find in the U.S., buyers should verify the exact model, intended market, parts support, and warranty before paying. A low listing price may reflect used equipment, old inventory, or a unit without local warranty coverage.
With a compatible existing gas line, vent, and plumbing connections, installation may add $1,100-$2,000, bringing a typical replacement to roughly $2,000-$4,000. A new installation or a job requiring upgraded venting, gas piping, condensate drainage, or electrical work can raise the total to $3,500-$6,500 or more. The installed price depends more on the house’s existing connections and local parts support than on the heater’s nameplate price alone.
Gas tankless models are commonly compared by flow rate and temperature rise rather than tank capacity. A household may need about 5-8 gallons per minute (GPM) of peak flow, depending on how many showers and fixtures run at once. A qualified installer should check the specific Paloma model’s rating against the home’s incoming water temperature and simultaneous demand.
How gas piping, venting, and labor shape the quote
A quote should separate the heater from the work needed to make it function safely. Typical line items include removal of the old unit, mounting, water and gas connections, vent materials, electrical connection, start-up, and any permit or inspection charges. Scope varies substantially between a direct replacement and a conversion from a storage tank.
| Quote item | Typical price | Unit or scope | What changes the amount |
|---|---|---|---|
| Paloma unit | $900-$2,200 | Per heater | Model, condition, seller, and availability |
| Installation labor | $600-$1,500 | About 6-12 hours | Access, connection changes, and crew rate |
| Venting and termination | $250-$900 | Per installation | Vent material, route length, and wall or roof exit |
| Gas-line changes | $300-$1,200 | Per job | Pipe diameter, distance, and available gas capacity |
| Removal and disposal | $100-$350 | Per old heater | Haul distance and disposal requirements |
| Permit and inspection | $50-$400 | Per local jurisdiction | Permit rules and required inspection work |
Labor is often estimated by the hour or as a fixed project charge. For budgeting, $75-$150 per technician-hour is a common broad planning range, but licensed plumbing and gas rates vary by metro area and job conditions.
Some quotes combine labor and standard fittings into one installation figure, so the component ranges should not simply be added to a contractor’s bundled total. Ask whether the quote includes start-up, leak testing, venting, removal, permit fees, and any required code corrections. A detailed written scope makes competing Paloma installation estimates easier to compare.
Which GPM rating and vent route raise the price?
Capacity is a major specification. A heater rated around 5-6 GPM may cost less than a larger 8-10 GPM model, but actual output falls as the required temperature rise increases. In colder regions, incoming water may be much colder in winter, reducing the flow available at a comfortable shower temperature. An undersized unit can lead to poor performance even when the purchase price looks attractive.
Gas supply is another threshold to check. A long run, an undersized branch, or several other gas appliances sharing the line may require a larger pipe or revised layout. If the heater is more than about 20-30 feet from an available suitable gas connection, added piping and labor can become a meaningful expense. The installer should confirm the appliance input rating and pipe sizing rather than assume the old tank heater’s line will work.
Venting also affects the estimate. A direct replacement using an approved, compatible route may keep the change modest; a new wall or roof penetration, longer vent path, or material change can add several hundred dollars. Condensing models may require a condensate drain and appropriate disposal route. Buyers should not assume an existing vent is reusable until the exact heater instructions and local code requirements are checked.
Other cost drivers include water hardness, outdoor exposure, distance from the plumbing manifold, and the condition of the mounting surface. Hard water may require more frequent descaling or treatment equipment. A unit installed outdoors may need freeze protection appropriate to the local climate. Confirm the model’s GPM at the home’s winter temperature rise and its approved vent configuration before comparing equipment prices.
Where can buyers trim a Paloma installation quote?
The most reliable savings come from controlling scope, not skipping safety work. If an existing gas line, vent route, and water connections meet the new model’s specifications, a like-for-like replacement can avoid unnecessary reconstruction. Ask the contractor to identify any proposed upgrade that is required by the manufacturer or code and distinguish it from optional improvements.
Compare at least two or three itemized quotes using the same model and included work. Check whether each price includes tax, permit, disposal, vent parts, isolation valves, start-up, and labor warranty. A quote that is several hundred dollars lower may exclude a permit or assume existing connections are reusable. Confirm the model number and whether it is new, refurbished, or used.
Material choices can matter, but compatibility and listing requirements come first. Use the vent material and fittings specified for the exact appliance rather than substituting a cheaper component. If the current heater is still operating, scheduling a planned replacement during a contractor’s less busy period may reduce urgency-related charges, though seasonal discounts are not guaranteed.
Ask whether a repair is practical before replacing a functioning heater. A diagnostic visit may cost $100-$250, and a repair such as replacing a sensor or valve can sometimes be less expensive than a full installation. For an older unit with unavailable parts, repeated faults, or a heat exchanger problem, repairs may provide limited value. Keep necessary gas, venting, and code work in the budget while questioning add-ons that do not solve a documented need.
How regional labor rates change the installed total
Installed pricing tends to be higher in dense coastal cities and other high-cost metro areas, where licensed trade labor, permits, and service demand cost more. A practical comparison is 10%-25% above a national planning estimate in expensive urban markets. Smaller cities and suburbs may fall closer to the middle of the ranges, while rural jobs can cost more if travel, limited contractor availability, or special-order parts are involved.
Climate affects more than labor. Colder incoming water can require a higher-output unit or a more careful capacity check, while freezing conditions can add installation requirements for an outdoor unit. Local codes may also affect vent termination, combustion air, seismic restraint, or inspection needs. These requirements are location-specific, so a national average cannot replace a local written estimate.
Paloma-specific availability may create a different regional price pattern from ordinary labor variation. A nearby distributor with legitimate inventory may offer a lower delivered price than a distant seller, while scarce parts can increase both freight and repair expense. Compare the delivered equipment price and local serviceability, not just the online listing amount.
How long does replacing a Paloma gas unit take?
A compatible replacement often takes one technician or a small crew about 6-10 hours, including removal, connections, commissioning, and basic testing. If the vent route, gas line, and water pipes need changes, work may take 1-2 days. A conversion from a conventional storage tank can take longer because the location and infrastructure were not designed for the tankless appliance.
Hourly charges may range from $75-$150 per technician, but many contractors use a fixed bid instead. The fixed price should state whether it covers travel, diagnostic work, start-up, and return visits. If a permit inspection is scheduled separately, the heater may not be ready for normal use until required approvals are complete.
Delays are possible when the exact Paloma model or compatible parts are not locally stocked. Before ordering, confirm the seller’s return policy and expected delivery date. A replacement unit should not be bought solely on the basis of a similar model name; connection sizes, gas type, venting rules, controls, and approvals must match the installation. Ask for the model-specific labor plan and a delivery contingency before setting a replacement date.
Three sample Paloma quotes for different house setups
These examples show how scope changes the total; they are planning estimates, not fixed national prices. Each assumes a residential natural-gas unit and ordinary contractor access. Local permit rules, equipment condition, and model availability can move the final quote beyond the example range.
| Scenario | Equipment | Labor and other work | Estimated total |
|---|---|---|---|
| Direct replacement, existing compatible vent and piping | $1,100-$1,700 | 6-8 hours; $800-$1,300 labor, $150-$350 supplies and disposal | $2,050-$3,350 |
| Replacement with gas-line and vent adjustments | $1,300-$1,900 | 8-12 hours; $1,000-$1,800 labor, $500-$1,200 materials and permit | $2,800-$4,900 |
| New tankless installation from a storage-tank setup | $1,400-$2,200 | 10-16 hours; $1,300-$2,400 labor, $700-$1,900 vent, gas, and plumbing work | $3,400-$6,500 |
In the first example, the price assumes the new heater is approved for the existing vent configuration and the gas supply is adequate. The second assumes a short but necessary piping or vent change. The third allows for new infrastructure and may still exclude major electrical upgrades, wall repair, or unusually long gas runs.
For a quote near the high end, request the measured vent length, gas-pipe size, labor hours, and material list. For a quote below the low end, check whether the equipment is used, whether removal is excluded, and whether the seller provides a valid warranty in the United States. Matching the quote to the actual home conditions is more useful than comparing totals without scope details.
Paloma availability, warranty, and five-year upkeep expense
Before paying for a Paloma-branded unit, confirm that the model is intended for U.S. installation and that the manufacturer or authorized service channel can support it. Some products may appear in resale listings or come from other markets; those units can have different fuel specifications, certifications, manuals, and warranty terms. A low purchase price may not compensate for unavailable parts or limited local technician familiarity.
Budget about $100-$300 per year for inspection and flushing when service is needed, with frequency influenced by water hardness and manufacturer instructions. Over five years, routine service could total roughly $500-$1,500, excluding repairs. Scale buildup can affect performance, so homes with hard water may need more frequent flushing or a water-treatment solution. Confirm the maintenance schedule for the exact model rather than relying on a generic tankless interval.
Warranty coverage should be checked in writing for the heat exchanger, other parts, and labor. A long parts warranty does not necessarily cover installation labor, travel, or a replacement unit bought from an unauthorized seller. A comparable currently supported tankless model may have a higher upfront price but easier access to service and parts. Include verified U.S. warranty and parts availability in the purchase comparison alongside unit price and installation cost.
