Description
Silent, fully electric hot water device for professional weed control. The Pro SP is a fantastic addition to comprehensive garden maintenance. It can be used, for example, in residential gardens, special park sites, and traffic divider areas.

With Eco Weedkiller Pro SP you can treat 100-150 green square metres daily
Eco Weedkiller Pro SP has a 300-litre water tank. 2–3 litres of hot water are needed per square metre in areas with 100% greenery coverage, for the treatment to be successful. This means that 300 litres of water is enough for 100–150 green square metres. Hot water both stores heat energy and acts as an agent to transfer it all the way to the roots. That is why it is crucial to use the recommended amount of water to achieve effective, lasting results.
Utililize the pre-heated water or heat the water with solar energy
Customer feedback shows that people want to use their existing heat sources to warm the water. The Pro SP series can flexibly utilise preheated water at temperatures 5–80 degrees Celsius. The traditional devices based on diesel-run heaters cannot offer the same advantage. The heating is powered by electricity, but you can choose the method for generating the energy needed, which helps reduce environmental impact.
Freedom to move
The device does not need to be connected to an electricity network or a water supply during operation. You can work wherever you wish. Eco Weedkiller Pro SP to perform very short spot treatments, for example dandelion control on lawns or planting areas, while maintaining a consistent water temperature. The device retains its heat for at least 6 hours after the power supply is disconnected.
Virtually silent to use
Pro SP is nearly silent in operation; only the hiss of the nozzle lets the user know that the water is hot enough for weed control. This makes Eco Weedkiller Pro SP an excellent choice for locations where noise could be disruptive, such as parks or schools.

Root cause
Our devices destroy weeds and invasive species down to the roots with hot water – completely without pesticides. Hot water is an unfamiliar threat to plants, one they have not developed protection against. Eco Weedkiller devices always produce 100 °C water, and thanks to their technology, the water remains hot until it reaches the root, destroying it with the thermal energy it carries.
How does Eco Weedkiller work?
Fill the device with normal tap water
Wait for the water to heat up to 100°C
Apply water to the unwanted plants
Remove the dead plants as needed
Repeat 3-4 times yearly to destroy the roots
