The primary house I lived in with my future spouse was an outdated railroad-style place that was heated by an historic “gasoline on gasoline” range within the kitchen. Within the winter months, cranking up so far as it might go meant the kitchen was roughly the temperature of the solar, and the lounge—two rooms away—was like the floor of Pluto. And after we obtained our first utility invoice, our souls briefly left our our bodies.
And compared to at this time, power was low cost again in these days. With the price of (checks notes) all the pieces rising, heating our houses has grow to be what scientists name “insanely costly.” The prices of electrical energy and gasoline have risen dramatically within the final 12 months alone, leaving many of us dealing with untenable utility payments and ice-cold houses.
If you happen to’re dealing with steep heating payments however your own home has a wood-burning fire that appeared like a pleasant amenity if you purchased it, it’s pure to surprise for those who may return a century and save some huge cash by burning wooden as an alternative of counting on a boiler, furnace, or baseboard warmth to maintain heat. In spite of everything, gasoline and electrical energy are costly, wooden is comparatively low cost, and a number of million folks in the USA nonetheless depend on wooden as their major or secondary heating technique—so heating your property with wooden is certainly viable. The query is whether or not it makes financial sense.
Twine prices
Assuming you’ve a fire that’s in good situation and may be fired up instantly, the primary query is how a lot it’ll value you in wooden to warmth your property. If you happen to dwell in a rural space and you’ve got entry to free wooden, your prices will likely be in effort and time as an alternative of cash—however think about the truth that firewood needs to be seasoned and dried. Burning damp, “inexperienced” wooden is rather a lot tougher and a lot much less energy-efficient. Seasoning firewood takes not less than a 12 months, and the wooden needs to be saved off the bottom and in a protected space the place it gained’t get moist every time it rains.

If you have to buy your wood, your costs will vary depending on local prices and how large a space you need to heat. In general, you need about three cords of firewood to warmth 1,000 sq. toes of inside area for a complete winter in chilly temperatures. A wire of wooden is a stack of wooden that measures 128 cubic toes—usually a stack that measures 4x4x8 toes. Sometimes a wire of wooden will run you an common of about $300, although costs will certainly differ relying on the place you reside.
So you probably have a 2,000-square-foot residence, you’ll want six cords of wooden (and the area to retailer it correctly) and it’ll value you roughly $2,000. That is perhaps a major financial savings over your gasoline or electrical invoice.
Effectivity
Whereas shopping for wooden to warmth your property is perhaps cheaper than shopping for gasoline or electrical energy, that’s not the entire story, because open wood-burning fireplaces are extremely inefficient.
There are two measurements right here. The primary is the combustion effectivity of the fireside, which describes the flexibility of your fire to show your wooden into warmth. However a lot of the warmth produced by your fire doesn’t make it into your own home. The total effectivity of the fireside measures how a lot warmth is definitely pushed into the inside, versus escaping up the chimney. The combustion effectivity is all the time a a lot greater quantity—the general effectivity for a conventional wood-burning fire is often about 10 p.c. You’ll be able to add glass doorways to your fire to deliver that quantity as much as a whopping 20 p.c.
Which means most of your warmth goes straight up the chimney. As the hearth heats up the air within the fireplace, the air rises, producing drafts that pulls air from the room together with it. This could truly make your room colder, which is one motive individuals are typically depicted sitting proper up near a roaring fireplace, smothered in blankets. And for those who’re utilizing your fire in only one space of the home and counting on different warmth sources for the remaining, this will truly improve your heating prices until you’ve a zoned heating system that lets you isolate the fireside space from the remainder of the home.
A hearth insert might help
If you happen to’re making an attempt to warmth only one small room with a wood-burning fire, you is perhaps okay. However for those who’re making an attempt to warmth a bigger area, the effectivity downside will wreck your firewood funds.
One resolution, for those who can afford it, is to go along with a fire insert. It is a self-contained, sealed unit that’s put in inside your current fire, usually with a stainless-steel chimney liner. These inserts burn wooden, however achieve this in a rather more environment friendly method, reaching total effectivity scores over 70% and typically even over 80%. These may be dear (starting from $2,000 to almost $5,000 or extra, not counting set up), so that you’ll should do some math round recouping your funding. However a wood- or pellet-burning insert could make utilizing wooden as a heating gasoline supply a viable possibility on your residence.
Fireplaces are cool, cozy, and even helpful—however for those who’re plotting to revamp your funds round chopping wooden free of charge and heating your property like a Nineteenth-century pioneer, crunch these numbers very rigorously. Heating your own home with a wood-burning fire isn’t a slam-dunk, in budgetary phrases.
