Real heat for Sheboygan County's long, cold winters.
With average winter lows near 12°F and over 7,500 heating degree days a year, Plymouth homes need reliable heat. Find the right gas fireplace or insert and get matched with a trusted local dealer.
Every Project Starts From One of These Five Situations
Instant warmth for a town built on cold winters.
Plymouth sits in Sheboygan County at just under 900 feet elevation, but the Wisconsin winter doesn't care about elevation—this is a Climate Zone 6A town with roughly 7,518 heating degree days a year, a load closer to Duluth, Minnesota than to most of the Midwest. Winter lows average 12°F, and the cheese-country town known as the historic Cheese Capital of the World sees plenty of stretches where a furnace alone struggles to keep up in older farmhouses and early-1900s homes near downtown.
Most homes inside Plymouth city limits have natural gas service available through the regional utility serving Sheboygan County, which makes a direct-vent gas fireplace or insert a straightforward add for in-town homeowners. Out in the surrounding townships, where gas mains don't always reach, propane from a local supplier fills the same role. Either way, a gas fireplace gives you real, instant heat at the flip of a switch or a wall switch—useful for a zone-heated sunroom, a finished basement, or simply taking the edge off a January cold snap without running the furnace all night.

Frequently Asked Questions
How much does a gas fireplace installation cost in Plymouth?
Most gas fireplace and insert installations in and around Plymouth run somewhere between $4,000 and $9,500, depending on the unit, the venting path, and whether a new gas line needs to be run. A direct-vent insert going into an existing masonry fireplace with gas already nearby tends to land on the lower end. New construction, additions, or homes needing a fresh gas line from the meter to a new fireplace location push toward the higher end. If you're on propane rather than natural gas, factor in tank placement and line work as part of the estimate—a local retailer will walk your home before quoting a firm number.
Can I convert an existing wood-burning fireplace to gas?
Yes, and it's a common project in a town like Plymouth with a good number of homes built in the early 1900s that still have their original masonry fireplaces. A gas insert slides into the existing firebox and uses a stainless liner run up your current chimney, so you keep the look of the original hearth while gaining real, controllable heat and losing the wood handling and ash cleanup. Typical cost runs $4,000 to $8,500 depending on the insert and whether you're on natural gas or propane. Homes already plumbed for gas elsewhere in the house are usually the easiest and cheapest conversions.
Should I install a natural gas or propane fireplace?
It depends on where in Sheboygan County you're located. Homes inside Plymouth's city limits generally have natural gas service available and already run gas to a furnace, water heater, or range, which makes adding a gas fireplace simple. Homes out in the surrounding townships, where the gas main doesn't reach, typically run on propane from a local delivery supplier, either with an existing tank or a new one sized for the fireplace. Nearly every gas fireplace model on the market can be set up for either fuel—your installer just configures the correct orifice and regulator for whichever gas you're on.
Will a gas fireplace still work if the power goes out?
Most modern direct-vent gas fireplaces will, which matters here given how often winter storms in Sheboygan County knock out power for a few hours at a time. Units with IPI (intermittent pilot ignition) run on a battery backup—usually a set of AA batteries built into the control module—that kicks in automatically and lets the fireplace light and run normally even with no grid power. Valor units take a different approach: their pilot generates its own electricity through a thermocouple, so there's no battery to remember to replace. If backup heat during an outage matters to you, ask your local dealer about the ignition system on any unit before you commit.
What's the difference between a gas fireplace, gas insert, and gas stove?
A gas fireplace is a fully framed-in unit, typically chosen for new construction or a remodel where there's no existing masonry fireplace. A gas insert is built to drop into an existing fireplace opening and vent through the current chimney with a liner, which is the more common route for Plymouth's older in-town homes. A gas stove is a freestanding cabinet-style unit that sits on the floor and vents through the wall or roof, often used in a basement, addition, or a room without an existing chimney at all. Most homeowners here with an old masonry fireplace end up choosing an insert; homeowners finishing a basement or building new usually go with a stove or built-in fireplace.
Do I need a permit to install a gas fireplace in Plymouth?
Yes. Gas fireplace installations fall under Wisconsin's Uniform Dwelling Code, and you'll need a building permit through the City of Plymouth's building inspection office, plus sign-off on the gas line work itself, which has to be done by a licensed plumber or gas fitter. Most established hearth dealers handle the permit application and inspection scheduling as part of the installation, so you're not coordinating trades yourself. This is one of the practical reasons to go through a trusted local dealer rather than a big-box purchase with a subcontracted install.
Are vent-free gas fireplaces allowed in Plymouth?
Vent-free (unvented) gas fireplaces are legal to install in Wisconsin, but they come with real restrictions—minimum room size requirements, oxygen depletion sensors, and rules against installing them in bedrooms or small enclosed spaces. They release combustion byproducts, including water vapor and small amounts of carbon monoxide, directly into the room instead of venting outside. Direct-vent gas fireplaces, which draw combustion air from outside and exhaust it back outside through a sealed pipe, are the far more common and generally recommended choice for Plymouth homes—they deliver real heat without any indoor air quality tradeoffs. Ask your dealer to walk through both if you're weighing a smaller installation.
How often does a gas fireplace need to be serviced?
Plan on an annual inspection, ideally in late summer or early fall before the heating season ramps up. A technician checks the burner, pilot assembly, gas connections, and venting, and cleans the glass and interior—a much lighter job than a wood chimney sweep, but not one to skip given how hard these units run through a Sheboygan County winter. Annual service typically runs $150 to $250 through most local gas appliance service providers.
Gas vs. electric fireplace—which makes more sense in Plymouth?
Gas gives you real heat output, useful for actually taking the edge off a room during a Wisconsin cold snap, plus the option to run during a power outage if you choose an IPI or Valor-style unit. Electric fireplaces plug into a standard outlet, need no venting or gas line at all, and install for a fraction of the cost—often under $1,000 including labor—which makes them a good fit for a rental, a bedroom, or a room where running gas isn't practical. Plymouth's municipal electric utility keeps residential rates relatively affordable at just under 12 cents per kWh, which helps if you're leaning electric for supplemental ambiance rather than primary heat. For a main living space that needs to genuinely offset furnace load in January, gas is usually the better long-term choice.
What's the difference between an insert and a zero-clearance fireplace?
An insert is a fireplace that slides into a pre-existing wood-burning fireplace—if you don't have one, there's nothing to insert it into. A zero-clearance fireplace is built into a framed wall, which makes it the answer for remodels and new construction. Simple test: existing masonry fireplace means insert; blank or framed wall means zero-clearance.
Why is my open fireplace making my house colder?
Open fireplaces suck—literally. As the fire burns, it consumes air your furnace already paid to heat and pulls it out through the chimney, so the house is actually colder after the fire goes out than before you lit it. An insert fixes this: it seals the chimney, puts fixed glass across the front, and turns that hole in your house into a real heat source.
Can I install a fireplace myself?
If you're putting a fire in your house on purpose, it's best to work with an expert. Unless you're genuinely experienced in framing, gas line, vent pipe, and the national code on clearances to combustibles, have a professional do it—and ideally the same company that sells you the fireplace, so warranty, service, and liability all live under one roof.
Does a fireplace add value to my home?
On average, a fireplace adds back to the home about the same amount you spent installing it. Add the monthly savings from heating the rooms you actually use instead of the whole house—often hundreds of dollars a year—and the value case is strong before you even count what a fire does for how your family uses the room.
