Electric Log Splitters: Preparing Firewood for Home, Country House and Sauna

A horizontal model pushes a log lying down onto the wedge and suits household work with 4–7 tonnes of force. A vertical model splits heavy, thick logs that are hard to lift onto a table. There are also cone (screw) splitters that work without hydraulics.

For softwood up to 25–30 cm in diameter, 4–6 tonnes is enough, while oak, beech and thick logs need 7–12 tonnes. Wet and knotty wood needs more force than dry wood. Choose the force for your wood species and diameter with some margin.

Household horizontal models usually take logs up to 37–52 cm long and 25–35 cm in diameter. The log length should match your stove or fireplace so you do not need to re-cut. Some models have a cross wedge that splits the log into four pieces at once.

Household 220–230 V models usually have a 1.5–3 kW motor, while models above 8 tonnes often run on 380 V. Check that the circuit and breaker can handle the starting current. Read how to choose tool power (W) and volt (V).

A log splitter usually works outdoors, so you need an outdoor extension cord of adequate cross-section. A cord that is too long and thin drops the voltage and can prevent the motor from starting. See how to use an extension cord safely.

Household horizontal models weigh 40–100 kg and have wheels for moving around. Cycle time (wedge forward and back) is usually 10–25 seconds and determines working speed. Check the oil level and the hydraulic system maintenance requirements.

Choose a model with two-handed operation, which keeps your hands away from the wedge while it moves. Wear gloves, glasses and sturdy footwear, and never split wood containing nails or metal. Read essential power tool safety rules and how to choose personal protective equipment.
