Reliable Gas Heat for Kenmore's Lake Washington Homes.

Most Kenmore gas fireplace and insert installations run $4,500 to $10,500, depending on the unit, the venting path, and whether new gas line work is needed. Converting an existing open masonry fireplace to a direct-vent gas insert—a common project in Kenmore's older lakeside neighborhoods—tends to land on the lower-to-middle end when a gas line is already nearby. New construction or a fireplace added where none existed, requiring framing, venting, and a fresh gas line run from the meter, sits toward the higher end. A local retailer will give you a firm number after seeing your home.

Yes, and it's one of the most requested projects among Kenmore homeowners with an older masonry fireplace that mostly sits unused. Because the mild Puget Sound climate rarely requires wood as a primary heat source, many of these fireplaces were built for occasional use and are good candidates for a direct-vent gas insert that reuses the existing chimney with a stainless liner. Expect the conversion to run in the $4,500 to $9,000 range locally, with the final number depending on whether the home already has a nearby gas line through Puget Sound Energy or needs new line work run to the hearth.

Either works, but natural gas is the more common setup in Kenmore. Puget Sound Energy provides natural gas service through most of the 98028 zip code, so if your home already has a gas water heater, range, or furnace, adding a fireplace typically means tapping into an existing line. Homes outside PSE's gas footprint—more common toward the edges of North King County—usually run propane instead, with a tank supplied by a local propane provider. Most gas fireplace models can be configured for either fuel; your installer sets the correct orifice and pressure regulator for whichever you have.

Most modern direct-vent gas fireplaces will, which matters in a place like Kenmore where December and January windstorms off Puget Sound regularly knock out power for a day or more. Units with intermittent pilot ignition (IPI) run on a small battery backup that kicks in automatically when the power drops, so the fireplace lights on demand just like normal. Valor's gas fireplaces take a different approach—the pilot's thermocouple generates its own electricity, so there's no battery to remember at all. Ask your local retailer which ignition system a given model uses if outage performance matters to you.

A gas fireplace is a fully built-in unit framed into a wall—the right call for new construction or a remodel without an existing chimney, which describes a lot of the newer townhomes and infill going up around Kenmore. A gas insert slides into an existing masonry firebox and uses the chimney you already have, which suits the older lakeside homes with a rarely-used wood fireplace. A gas stove is a freestanding unit that sits on the floor on its own hearth pad, useful when you want supplemental heat in a room without any existing fireplace opening at all.

Yes—the City of Kenmore Building Department requires both a building permit and a gas line permit for a new gas fireplace or insert installation. The gas line work has to be done by a licensed gas fitter, which is part of why most homeowners let their hearth retailer handle it end to end rather than coordinating separate trades. Most local installers fold the permitting directly into the installation quote, so it's rarely something you have to manage yourself.

Vented (direct-vent) gas fireplaces draw combustion air from outside and exhaust the byproducts back outside through a sealed pipe. Vent-free units burn gas directly into the room with no outside venting at all. Washington is one of the states that restricts vent-free gas appliances, so direct-vent is effectively the standard—and the practical—choice for a Kenmore installation. It's also the better fit for a moisture-prone marine climate like this one, since direct-vent units don't add extra humidity to the indoor air the way vent-free units do.

Plan on an annual inspection, ideally before the fall rains set in. A certified technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior—a much smaller job than chimney sweeping but just as important for safety, especially on units that see heavy fall-through-spring use in Kenmore's damp climate. Local gas appliance service providers typically charge $150 to $250 for this visit.

Wood-burning fireplaces are genuinely uncommon here—the mild marine climate and regional air quality guidance around wildfire-smoke season mean most Kenmore homeowners weighing a new install are really choosing between gas and electric, not gas and wood. Gas delivers real heat output and the look of an actual flame, and it works during power outages with battery-backup ignition. Electric fireplaces cost far less to install—often under $1,500—plug into a standard outlet, and produce zero emissions, but at Puget Sound Energy's residential rate of roughly 14.6 cents per kWh, running one as a primary heat source costs more per BTU than gas over a full winter. For a den, bedroom, or rental unit, electric is often the simpler answer. For a main living space where you want real heat and ambiance, gas is usually the better long-term investment.

Yes—with an asterisk. Fireplaces are hot and TVs don't like heat. Either put a mantel between them to deflect rising warmth, or choose a fireplace with heat-management technology that creates a cool zone on the wall above—the wall stays around 125 degrees, barely warm, while the room still gets full heat. If you like clean lines and don't want a mantel, heat management is the answer.

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.

Yes—by creating a comfort zone. A furnace heats every square foot of the house just to warm the one room you're in; a gas fireplace on low burns roughly a sixth of the gas a typical furnace does. Set the furnace around 55–60 degrees as a baseline, then heat the rooms your family actually uses. Families who heat this way commonly save $20–$60 a month.

It's a visit where a hearth professional measures your space, confirms the model you picked actually works in your home, and walks the specs—framing, gas line, venting, finish work—before anything is ordered. Some details you just can't know until you see the house. Never make a down payment without one; it's the single most-skipped step that burns buyers.
