Pellet stove vs wood burner: which is right for your home?

Neither is simply better. A pellet stove is more controllable, more efficient and cleaner-burning, but it needs electricity and yearly servicing. A wood burner is simpler, works in a power cut and gives a real open flame, but it is less efficient and more hands-on.

Control and efficiency

The biggest practical difference is control. A pellet stove feeds itself from a hopper using an electric auger, and you set a target temperature on a thermostat, a timer or even an app, so it behaves much like a gas appliance: it lights itself, holds the temperature and shuts down on a schedule. A wood burner is manual throughout, you light it, feed it logs and manage the air to control the burn, which some owners love and others find a chore. If you want set-and-forget heating, the pellet stove wins clearly.

Efficiency follows from that control. Modern pellet stoves to the BS EN 14785 standard typically achieve 87 to 91 percent seasonal efficiency, because the controlled, optimised burn wastes little fuel; the stoves in our test measured between 87.4 and 90.5 percent. A modern Ecodesign wood burner is good but generally lower, often in the 75 to 80 percent range, because a hand-fed log fire is harder to keep in its optimal burn. Over a season that efficiency gap shows up in how much fuel you get through for the same heat.

Running cost

Running cost depends almost entirely on your fuel access. If you can source cheap or free seasoned logs, perhaps from your own land or a local supply, a wood burner can be the cheaper option to run despite its lower efficiency, because the fuel itself costs little. If you buy kiln-dried logs at retail prices, the maths flips: a pellet stove burning at around 90 percent efficiency usually costs less per useful kilowatt-hour, because pellets are an energy-dense, consistent fuel and very little is wasted.

The UK Department for Energy Security and Net Zero fuel price data through 2026 shows wood pellets remaining competitive with other domestic fuels per useful kilowatt-hour, while retail kiln-dried logs vary widely by supplier. Our pellet stove running costs guide works through the pellet numbers in detail. The honest summary: if you have access to inexpensive logs, a wood burner can be cheaper; if you will buy fuel at retail prices, the pellet stove's efficiency usually makes it the cheaper choice over a season.

Maintenance and effort

Both need regular care, but in different ways. A pellet stove needs the ash pan emptying every few days, the burn pot and combustion chamber vacuuming weekly, and a professional service and flue sweep once a year. It has electrical and mechanical parts, the auger, fan and igniter, that can eventually fail and need replacing. A wood burner has fewer parts to break but more daily effort: you fetch, split, season and store logs, light the fire each time, manage the air, and sweep a larger chimney, usually more than once a season for a heavily used burner.

The day-to-day effort question is really about lifestyle. A pellet stove suits someone who wants warmth at the press of a button with modest, predictable maintenance. A wood burner suits someone who enjoys the ritual of tending a fire and has somewhere to store logs. Neither is objectively harder; they ask for different things. If the idea of splitting and stacking logs appeals, the wood burner; if you would rather load a hopper once a day and forget it, the pellet stove.

Flue rules and the power question

Both must comply with Building Regulations Approved Document J and be installed by a competent person, but their flue needs differ. A pellet stove can use a smaller-diameter sealed flue, typically 80 mm, and can sometimes vent horizontally through a wall, which makes it possible to fit in homes without a chimney. A wood burner needs a full chimney or a larger twin-wall flue and cannot vent through a wall, so it is more constrained by your building. In a smoke control area both must be DEFRA-exempt models to be used legally.

One genuine advantage sits firmly with the wood burner: it needs no electricity. In a power cut a pellet stove stops, because its auger and fan have no power, unless you have fitted a battery backup, whereas a wood burner keeps burning regardless. If you live somewhere with frequent outages, or you want a heat source that works when the grid fails, that resilience is a real point in the wood burner's favour. For most homes with a reliable supply, it is a minor consideration.

Which suits you

Choose a pellet stove if you want controllable, efficient, low-particulate heat with thermostat and timer control, you will buy fuel at retail prices, and you value convenience over ritual. It is the better choice for most modern households, and our best pellet stove ranking shows the strongest current models, from the efficient MCZ Suite to the value Ravelli Holly 9. Choose a wood burner if you can get cheap or free logs, you enjoy tending a real fire, you want heat that works in a power cut, or you simply love the look and crackle of burning wood.

There is no wrong answer, only the right fit for your home and your temperament. If you are still unsure, work out your room size with our how many kW do I need guide and your likely running cost with our running costs guide, then decide. Whichever you choose, use a HETAS-registered installer and a compliant flue, because a safe, certified installation matters far more than which fuel you burn.
