Is it right for you?
Who the ACR Woodpecker WP4 Wood Burning Stove suits best
The WP4 is the small-room specialist: 4.3kW nominal in a body just 373mm wide and 469mm tall. Snugs, home offices, small cottage rooms and bedrooms-turned-sitting-rooms are its territory, the spaces where a 5kW stove would cook you out of the room. It burns seasoned logs and compressed heat logs, and it is the most affordable woodburner in our range.
From the survey
Installation notes for the ACR Woodpecker WP4 Wood Burning Stove
The smallest chambers take it: at 373mm wide it fits openings that rule out nearly everything else we sell. A 125mm flue and 12mm hearth keep the fit simple, and it takes logs up to 30cm, so ask your log supplier for the shorter cut. In really tight rooms we pay extra attention to clearances, which is standard survey work.
An honest steer
How it compares with similar models
The WP4 LS is this stove on an integrated log store base, taller and freestanding-friendly for the same firebox. Step up to the WP5 for a full 5kW and 40cm logs if the room can take it. Honest guidance: in a genuinely small room the WP4 is the better stove, because a bigger stove run shut down burns dirty.

Common questions
ACR Woodpecker WP4 Wood Burning Stove FAQs
What room size suits the ACR Woodpecker WP4?
Small rooms, roughly up to 60 cubic metres of typical space: snugs, studies and cottage sitting rooms. Its 4.3kW nominal output is the honest match for spaces where a 5kW stove would overheat.
What fuels does the WP4 burn?
Seasoned wood logs and compressed heat blocks. It is a dedicated woodburner rather than a multifuel, and its DEFRA exemption covers wood burning in smoke control areas.
How small is the WP4 really?
Just 373mm wide, 469mm tall and 66kg, one of the most compact proper stoves on the market, which is why it fits fireplaces that rule out nearly everything else.
What logs fit the WP4?
Logs up to 30cm. Most suppliers offer a short cut, worth requesting when you order. If you want a compact stove that takes standard 40cm logs, look at the WP5.
