Fireplace Insert Cost 2026: Gas, Electric & Wood, Installed

A fireplace reface and a fireplace insert are different purchases. Refacing changes the visible surround. An insert changes the appliance inside the opening, with installation requirements that can include venting, utilities and finish repairs. Start by deciding which result you need.

How much do fireplace inserts and refacing cost?

A quote above a published range is not evidence of misconduct. It is a reason to identify the additional work and compare it with another proposal. A very low appliance price is not evidence of a low completed-project cost either.

Why is one gas-insert quote thousands higher?

Ask the installer to separate the appliance package from the house work. A proposal may already include the required vent components; adding a second generic “chimney liner” allowance would count part of the work twice. Conversely, a listed appliance may exclude the surround, trim or controls you saw in the showroom.

Heat & Glo's installation overview illustrates why venting, utilities and professional installation belong in the discussion. Have the installer use the manual for the exact model to establish compatibility and clearances. An opening that looks large enough is not a complete fit assessment.

Gas, electric or wood: which suits the way you will use it?

For heat, ask about the room, the intended hours of use and the appliance's output and controls. For occasional ambiance, ask how it operates without heat and what it looks and sounds like in that mode. See the selected model running before making appearance the deciding factor.

For operating cost, use the actual energy input and your utility rate. As an arithmetic example only, a 1.5 kW electric heater running continuously for three hours uses 4.5 kWh. Multiply that by the applicable rate; thermostat cycling and flame-only operation change consumption. This is not a promised hourly cost for every fireplace.

Explore the fireplace and built-in project guide when the plan also includes cabinetry, a television or wall reconstruction. Those items should have their own scope, rather than disappearing into an “insert installed” total.

For electric models, use our electric fireplace insert comparison to distinguish the appliance options before requesting installation prices.

Can an EPA-certified wood insert be used during a burn ban?

Certification does not create a universal exemption. The Bay Area Air District restricts wood burning during Winter Spare the Air alerts, subject to its exemptions. Its rules also address new construction and qualifying fireplace remodels; check the applicable project requirements before selecting a wood appliance.

In the Puget Sound region, the agency's burn-ban guidance distinguishes Stage 1 from Stage 2. Certified devices can be restricted under Stage 2 as well. Check the current notice and any approved exemption for your property. An installer saying “EPA certified” has not answered the use question.

What should you check before ordering an insert?

Get written approval of the selected model and installation approach from the responsible installer. Confirm the measured opening, required clearances, vent route, utility work and permit responsibility. Ask what happens if inspection reveals damage after the order is placed. If you are still choosing the model, the comparison of gas fireplace insert brands sets out published specs, warranties and list prices for 11 brands.

If you supply the appliance, clarify who receives it, checks shipping damage and handles warranty service. A manufacturer may address a defective part without covering every removal or finish-repair expense. Request the product warranty and workmanship terms separately, including the person to contact if the appliance fails after handover.

A bid request you can copy

Please quote the identified model with its accessories, required venting and utility work. List inspections, permits, removal, surround and finish repairs as included, excluded or unresolved. Identify allowances, possible repair work and the approval process for changes. Please confirm who handles product defects and installation callbacks.

What does installing a fireplace insert involve?

An insert is a closed appliance that slides into an existing masonry or factory-built firebox. The appliance is only part of the job. Each fuel type brings its own venting and utility work, and that work explains much of the spread between quotes.

Gas inserts: two liners, a gas line and power

Most gas inserts vent up the existing chimney through new flexible pipe, not through the old flue itself. Heat & Glo's venting guide describes two flexible 3 inch aluminum liners running side by side: one brings in outside air for combustion, the other carries exhaust out. The insert stays a sealed, direct vent system, so the fire does not pull air from the room.

The same manufacturer's installation walkthrough lists the steps in order. The crew cleans the firebox and flue, runs electrical power and mounts an outlet inside the fireplace, runs a gas line, drops the vent liner from the top of the chimney and caps it, then sets and levels the insert. Inspections come before the final hookup. Depending on where the gas source sits, the new line could be a couple of feet or fifty feet long, and it gets a pressure test before an inspector signs off. The walkthrough puts the full process at three to ten days and says plainly that it is not a DIY project.

That list is why two gas insert bids can be far apart. A house with a gas stub and an outlet near the hearth needs much less work than one where the gas line and the circuit have to cross the house.

Wood inserts: a stainless steel liner to the top

Wood inserts need a new liner too. Heat & Glo's venting guide says wood-burning inserts use a stainless steel, flexible single wall liner that runs up the existing chimney to the termination cap. The EPA installation and maintenance page calls the venting system the engine of the whole burning process. It lists the venting decisions a professional should make: sizing, height, location and protection from extreme cold, and configuration. It also names the install checks that matter most: clearances to combustible materials, protection of combustible floors, and correct assembly of the appliance and vent parts.

Electric inserts: often a dedicated circuit

Electric inserts need no vent, but they are not always plug and play. The owner's manual for one built-in or insert model, the Modern Flames Redstone, rates it at 120 volts and 1,465 watts (5,000 BTUs), with a low heat setting of 733 watts. It calls for a dedicated 15 amp (or higher) breaker. When the unit goes into an existing fireplace, the manual tells the owner to have a qualified electrician wire an outlet to the rear or side of the firebox. If no spare circuit runs near the hearth, that electrical work belongs in the quote.

Specs differ by model, so read the manual for the unit you pick. The electric insert comparison covers the appliance choices themselves.

What does EPA certification mean for a wood insert?

Federal New Source Performance Standards govern the manufacture and sale of wood stoves and certain wood-burning fireplace inserts. According to EPA's summary of wood heater rules, they cover new appliances and do not apply to devices already in use in a home. The federal rule does not force out an insert already in place, but a new one offered for sale has to meet it.

The limit dropped in 2020. New room heaters must meet 2.0 grams of smoke per hour when tested with crib wood, or 2.5 grams per hour with cord wood, according to EPA's certified wood stove page. EPA's stove buying guide compares that with older uncertified stoves, which release 15 to 30 grams of smoke per hour. To check a unit, look for the permanent metal EPA label on the back or search EPA's database of certified wood heaters.

Certified wood appliances use one of two designs. Non-catalytic units rely on firebox insulation, a large baffle and preheated air, and the baffle wears out with time. Catalytic units pass smoke through a coated ceramic honeycomb. EPA says the catalyst can last more than six seasons with proper use, but may break down in as little as 2 years if the stove is over-fired, burns the wrong fuel or is not maintained. Ask what the replacement part costs before choosing a catalytic insert.

A note on the source: EPA's Burn Wise program ran from 2009 to 2025, and the site is now a historic record that EPA stopped updating on October 30, 2025. The federal standards and the certified heater list are the parts to rely on.

California rules that apply to inserts

In California, the local air district decides which insert you can install, not only when you can burn it.

Bay Area: Regulation 6, Rule 3

The Bay Area Air District adopted amendments to Regulation 6, Rule 3 on October 1, 2025. Under its wood smoke rules, a chimney or fireplace remodel that costs over $15,000 and needs a building permit may only install a gas-fueled, electric or EPA-certified device. No wood-burning device of any kind may go into a new home or building.

The burn ban applies on any day of the year when a Spare the Air Alert is called for high fine particle pollution, including smoke from wildfires. A household that heats only with wood can be exempt only with an EPA-certified device registered with the Air District, and an open hearth fireplace never qualifies. Anyone selling, renting or leasing a Bay Area property must give a Residential Wood Burning Disclosure. The district's Clean HEET program offers up to $10,500 to replace a wood or pellet fireplace, stove or insert with an electric heat pump, or up to $1,000 to remove one without a replacement.

Southern California: South Coast AQMD Rule 445

In the South Coast Air Basin, Rule 445 limits what can be sold or installed in an existing home to four options: a dedicated gas-fueled fireplace, a U.S. EPA certified fireplace insert or stove, a pellet-fueled heater, or a masonry heater. Since March 9, 2009, new developments cannot add permanent wood-burning devices at all, apart from a limited allowance for devices lost to natural disasters.

Mandatory No-Burn alerts apply from November 1 through the end of February when fine particle levels are forecast to exceed 29 micrograms per cubic meter. As of September 2025, the low-income exemption is gone. A temporary gas or power outage does exempt a wood-burning device for the length of the outage. South Coast AQMD also says gas log sets cut fine particulates by 99 percent compared with an open hearth.

Two more California examples

EPA's summary of local rules lists two others. San Joaquin Valley Rule 4901 requires an existing wood stove to be replaced with an EPA certified wood stove when a home is sold, and only pellet, gas and EPA-certified wood stoves can be sold there. In Laguna Beach, any major remodel of a single-family home requires an existing wood fireplace to get a qualified retrofit insert, a conversion to gas only, or another approved device.

Washington and Seattle rules for inserts

Washington regulates which wood stoves and other wood-burning devices can be sold, resold, exchanged or given away. They must meet both Washington and EPA standards for certification and labeling, and the Department of Ecology says never to install a non-certified wood stove. Washington also charges a $30 fee on the sale of every wood-burning device to fund education and enforcement, according to EPA's summary of state rules.

For a gas insert in Seattle, the permits are split. An SDCI mechanical permit covers heating and venting equipment but not gas lines, which need a separate permit. The city's Fuel Gas Code page says gas piping permits are issued by Public Health, Seattle and King County. A licensed gas piping mechanic is the trade that installs piping from the meter to the appliance. Ask the installer who holds that license on the job.

Do you need a permit for a fireplace insert?

Often, yes, and the kind of permit depends on the work. San Diego's Information Bulletin 201 is a clear California example. It requires a building or combination permit for any masonry fireplace or wood-burning prefabricated fireplace. Some decorative gas fireplaces need no building permit but may need a plumbing or electrical permit. The bulletin says only a direct-vent sealed-combustion gas fireplace, a sealed wood-burning fireplace, or a sealed woodstove or pellet stove shall be installed, citing the California Energy Code. It also states that adding or replacing a fireplace requires a building permit.

Rules differ by city, so ask the installer which permits they will pull and who will meet the inspector. Heat & Glo's installation guide notes that larger cities can require multiple licenses and permits, and that a city may send a separate inspector for each category of work. For broader project pricing context, see the Renology cost index.

Is there a federal tax credit for a fireplace insert in 2026?

Not under the credit that used to cover efficient wood and pellet heaters. The IRS page for the Energy Efficient Home Improvement Credit says the credit can be claimed for improvements made through December 31, 2025. While it ran, biomass stoves and boilers with a thermal efficiency rating of at least 75% qualified for up to $2,000 per year. ENERGY STAR lists the same window: products purchased and installed between January 1, 2023, and December 31, 2025, with a credit of 30% of project cost.

Timing matters here. The IRS says the credit is claimed for the tax year the property is installed, not merely purchased. That means an insert bought in late 2025 but installed in 2026 falls outside the window as the IRS page reads today. Look at local programs instead, such as the Bay Area Clean HEET offer above, before counting on any incentive.

Chimney and carbon monoxide checks

A new liner does not fix a damaged chimney around it. EPA says fire officials recommend a professional inspection of the wood-burning appliance, chimney and vent every year. That includes looking for cracks, which can let smoke into the home or expose chimney parts to high temperatures. To find qualified people, EPA points to the Chimney Safety Institute of America for certified sweeps and the National Fireplace Institute for certified hearth technicians.

Any fuel-burning insert also raises carbon monoxide questions. California Health and Safety Code section 17926 requires owners to install an approved carbon monoxide device in each existing dwelling unit that has a fossil fuel burning heater or appliance, a fireplace, or an attached garage. The U.S. Consumer Product Safety Commission advises CO alarms on every level of the home and outside sleeping areas, and says interconnected alarms are best. Check those alarms as part of the insert project.
