Propane Heat That Works When the Power Doesn't.
Three Lakes sits off the natural gas mains, so propane does the work here. Find the right fireplace or insert for your home, and connect with a trusted local dealer who handles the tank, the venting, and the permit.
Every Project Starts From One of These Five Situations
No natural gas lines out here—propane fills the gap.
Three Lakes is an unincorporated community tucked into the Cascade foothills of Snohomish County, at about 620 feet elevation. Winters here are mild by national standards—average lows hover around 32°F rather than the deep-freeze numbers you'd see in Duluth or Fargo—but the heating season is long and damp, stretching across a wet, gray Pacific Northwest winter that keeps furnaces and fireplaces working for months on end. There's no municipal natural gas infrastructure serving Three Lakes, so when homeowners say they want a 'gas fireplace,' what they actually end up installing runs on propane.
Puget Sound Energy provides electric service to the area at roughly 14.6 cents per kWh, and the same wooded, hilly terrain that makes Three Lakes beautiful also makes it prone to windstorm-related outages—branches and trees down on power lines are a routine part of winter here. A direct-vent propane fireplace or insert with battery-backup ignition keeps a room warm and lit even when the grid goes down, which is a real, practical reason propane fireplaces are common in this part of Snohomish County rather than just a design choice.

Frequently Asked Questions
How much does a propane fireplace installation cost in Three Lakes?
Because there's no natural gas main to tap into, most Three Lakes installations include propane-specific costs on top of the fireplace itself. A direct-vent propane insert or fireplace, including a new above-ground propane tank, regulator, and gas line run to the unit, typically falls between $5,000 and $11,500. Homes that already have a propane tank and line in place for a furnace or water heater are usually on the lower end, since the installer only needs to tap into existing service. Local dealers will walk your property and give a firm number after seeing your chimney, tank placement, and run distance.
Can I convert my existing wood fireplace to propane?
Yes, and it's a common project for older Three Lakes homes with an existing masonry fireplace. A propane insert goes into the firebox with a stainless liner run up the existing chimney, and typically costs $5,000 to $9,500 depending on the insert and whether a new propane tank is needed. If your home already has propane service for heat or cooking, the conversion is simpler and cheaper—the installer just extends the existing line rather than setting a new tank.
Do I need natural gas, or is propane the only option?
For Three Lakes, propane is effectively the standard option—there's no natural gas utility serving this part of unincorporated Snohomish County. Most homes use either a 120-gallon or 250-gallon above-ground tank, filled by a regional propane supplier on a delivery schedule or automatic refill program. Nearly every gas fireplace, insert, and stove on the market can be configured to run on propane instead of natural gas—your dealer sets the correct orifice and regulator during installation, so fuel choice doesn't limit which units you can consider.
Will my propane fireplace work during a power outage?
Most modern propane fireplaces will, which matters here—the wooded terrain around Three Lakes means Puget Sound Energy outages from falling limbs and windstorms aren't rare in winter. Units with IPI (intermittent pilot ignition) run on a small battery backup that keeps the fireplace operating normally when the grid drops. Valor units go a step further: their pilot generates its own electricity through the thermocouple, so there's no battery to remember or replace. Ask your local dealer about ignition type specifically if outage backup is a priority for you.
What's the difference between a gas fireplace, gas insert, and gas stove?
A gas fireplace is a fully built-in unit framed into a wall, typically chosen for new construction or a remodel. A gas insert drops into an existing masonry firebox and uses the chimney as its vent path, which is the common upgrade for older Three Lakes homes with a wood-burning fireplace already in place. A gas stove is a freestanding cabinet-style unit that sits on the floor, useful in rooms without an existing fireplace or chimney chase. All three can run on propane here, so the choice usually comes down to what opening or footprint you already have.
Do I need a permit to install a propane fireplace in Three Lakes?
Yes—installations in unincorporated Snohomish County require a building permit through Snohomish County Planning and Development Services, and the propane line work needs to be done by a licensed gas fitter or propane technician. Most local hearth dealers coordinate the permit, the tank setup, and the final inspection as one package, so you're not stuck managing three separate trades yourself.
Should I get a vented or vent-free propane fireplace?
Vented (direct-vent) units draw combustion air from outside and exhaust it back outside through sealed venting—they're the standard, code-approved choice everywhere, including Three Lakes. Vent-free units burn directly into the room and release some moisture and combustion byproducts indoors, which is a harder sell in a climate that's already damp for most of the year; adding more humidity into a tightly built, energy-code Pacific Northwest home isn't something most local installers recommend. Direct-vent is what you'll find installed in the vast majority of homes in this area, and it's the option local dealers will steer you toward.
How often should a propane fireplace be serviced?
Plan on an annual inspection, ideally before the wet season starts in the fall. A technician checks the burner, pilot assembly, gas connections, and venting, and cleans the glass and interior components. This runs $150 to $250 in most cases and is a much lighter lift than wood-stove chimney sweeping, but it matters just as much for safe operation—especially for units that also serve as backup heat during winter outages.
Propane vs. wood—which makes more sense for a Three Lakes home?
Wood is genuinely practical here—Douglas fir, red alder, and lodgepole pine are all common locally, and Mt. Baker-Snoqualmie National Forest cutting permits run just $5 to $20 per cord during the May-to-October season for homeowners willing to cut their own. Wood also needs no fuel delivery and works with zero electricity. Propane wins on convenience: no splitting, stacking, or ash cleanup, instant on-off operation, and (with the right ignition system) reliable heat during the windstorm outages that hit this area most winters. A lot of Three Lakes households end up with both—propane for daily convenience in the main living space, wood as backup and ambiance elsewhere.
Is my gas fireplace wasting gas?
If it was installed more than 15 years ago, probably. Older gas fireplaces keep a standing pilot light burning all the time, and that little flame can cost a couple hundred dollars a year. Newer models use pilot-on-demand ignition—the pilot lights only when you use the fireplace and goes out when you turn it off.
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.
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.
How much should I budget for a fireplace?
For an average home—covering the fireplace, the vent pipe, and basic installation—a budget between $3,900 and $5,500 gives you a lot of options across wood, gas, and pellet. By the time you add finish work, gas line, and electrical, the average complete installation lands between $5,000 and $12,000 all-in. In a remodel or new build, a good rule is to put about 2.5% of the total project cost toward the fireplace.
