The primary house I lived in with my future spouse was an previous railroad-style place that was heated by an historical “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 once we obtained our first utility invoice, our souls briefly left our our bodies.

And compared to in the present day, power was low-cost again in these days. With the price of (checks notes) all the pieces rising, heating our properties has change into what scientists name “insanely costly.” The prices of electrical energy and gasoline have risen dramatically within the final yr alone, leaving many people going through untenable utility payments and ice-cold properties.

Should you’re going through steep heating payments however your home has a wood-burning fire that appeared like a pleasant amenity once you purchased it, it’s pure to surprise when you 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 any case, gasoline and electrical energy are costly, wooden is comparatively low-cost, and a number of million individuals in the USA nonetheless depend on wooden as their major or secondary heating technique—so heating your private home with wooden is unquestionably viable. The query is whether or not it makes financial sense.

Twine prices

Assuming you’ve got a fire that’s in good situation and might be fired up instantly, the primary query is how a lot it’ll price you in wooden to warmth your private home. Should you stay in a rural space and you’ve got entry to free wooden, your prices might 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 so much tougher and a lot much less energy-efficient. Seasoning firewood takes at the least a yr, 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 must purchase your wooden, your prices will differ relying on native costs and how massive an area you want to warmth. Generally, you want about three cords of firewood to warmth 1,000 sq. ft of inside house for an entire winter in chilly temperatures. A twine of wooden is a stack of wooden that measures 128 cubic ft—usually a stack that measures 4x4x8 ft. Sometimes a twine of wooden will run you an common of about $300, although costs will certainly differ relying on the place you reside.

So in case you have a 2,000-square-foot dwelling, you’ll want six cords of wooden (and the house to retailer it correctly) and it’ll price you roughly $2,000. That may be a big financial savings over your gasoline or electrical invoice.


Whereas shopping for wooden to warmth your private home may be 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 power of your fire to show your wooden into warmth. However many of the warmth produced by your fire doesn’t make it into your home. The general effectivity of the fireside measures how a lot warmth is definitely pushed into the inside, versus escaping up the chimney. The combustion effectivity is at all times a a lot greater quantity—the general effectivity for a standard wood-burning fire is usually about 10 %. You’ll be able to add glass doorways to your fire to convey that quantity as much as a whopping 20 %.

Meaning most of your warmth goes straight up the chimney. As the hearth heats up the air within the fireside, the air rises, producing drafts that pulls air from the room together with it. This will really make your room colder, which is one purpose individuals are usually depicted sitting proper up near a roaring hearth, smothered in blankets. And when you’re utilizing your fire in only one space of the home and counting on different warmth sources for the remaining, this will really improve your heating prices except you’ve got a zoned heating system that means that you can isolate the fireside space from the remainder of the home.

A hearth insert may also help

Should you’re attempting to warmth only one small room with a wood-burning fire, you may be okay. However when you’re attempting to warmth a bigger house, the effectivity downside will spoil your firewood finances.

One answer, when you can afford it, is to go together with a fire insert. It is a self-contained, sealed unit that’s put in inside your current fire, usually with a chrome steel chimney liner. These inserts burn wooden, however accomplish that in a way more environment friendly method, reaching general effectivity scores over 70% and generally even over 80%. These might be expensive (starting from $2,000 to just about $5,000 or extra, not counting set up), so that you’ll need to 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 choice in your dwelling.

Fireplaces are cool, cozy, and even helpful—however when you’re plotting to revamp your finances round chopping wooden without cost and heating your private home like a Nineteenth-century pioneer, crunch these numbers very rigorously. Heating your home with a wood-burning fire isn’t a slam-dunk, in budgetary phrases.
