Frequently Asked Questions

In practice, the difference relates to the requirements of the fuse in the property's outdoor socket and to the time in which 25 litres of about 4°C water are heated to 100 Celsius degrees. The fuse size found in the outdoor outlet affects how efficient you can use the device. If you have an outdoor socket with a 16 A fuse in your house, you can use either version. The heating time of the 3 kW version is about 1-1.5 h, compared to the 2kW version which is about 1.5-2 h. Connecting a 3 kW-powered device to a 10 A fuse socket burns the fuse and the heating of the appliance does not work. If you are using an extension cord to heat the appliance, it must comply with the requirements and are suitable for outdoor use. When used with a 3 kW device, the extension cable must be at least 3 x 2.5 mm² in wires. If a 2 kW device is used, an extension cord of 3 x 1.5 mm² of wires is sufficient. The extension cable should indicate the size of the wires, e.g. 3G2.5 mm², which means 3 x 2.5 mm². If you are not sure that your extension cord is appropriate, contact your dealer for advice. Never work with the appliance when the power cord is switched on. Never use a damaged extension cord.

The treated plant loses its “posture” and falls against the ground. For large-leaved plants, you may notice the smell of a “cooked plant,” and the soil may steam slightly. Using these simple observations, you can achieve professional-level weed control in yards and gardens.

n chemical-free methods, repeated treatment of unwanted weeds is the key to a good result. As a rule of thumb, 2–4 treatments per growing season are recommended, depending on the desired outcome. Since the soil is healthy, new plants will grow from seeds, but with regular treatment, the workload decreases annually and remains manageable. Timely treatment is the key to easy weed management.

Only fresh water should be used for weed control. Natural water sources are also usable, as long as care is taken to prevent debris from entering the machine. Using a filter or strainer is essential.

The Eco Weedkiller hot water device cannot be used with seawater, as seawater damages both the soil and the device, and its use is therefore prohibited.

It is impossible to answer this definitively. The treated area depends on the type of surface (gravel, paving, field soil, etc.), the amount of weeds present, and the types of weeds. Simplified, it is possible to treat a completely weed-covered area of 8–10 square meters with one tank.

A good result is obtained with 2-3 liters of water per completely green square meter

Nearly all plants can be killed with 100°C water. It is only a matter of water quantity needed to complete the task.

Hot water treatment is the only chemical-free method that also affects the plant’s roots. Standard treatment destroys the root system as well.

Boiling water is an unfamiliar threat to plants, for which they have not developed protection. Plants do have a natural ability to survive, for example, forest fires. Fires destroy above-ground parts, but most roots and seeds survive, and growth resumes soon.

Boiling water from a kettle produces better results. A steam cleaner’s ability to transfer energy is negligible for weed control.

A pressure washer is designed to remove dirt with high pressure. The water exits as very small droplets to adhere to dirt. Small droplets release heat quickly into the air and cannot transfer enough heat to plants, let alone their roots. High pressure also disturbs the surroundings and can, for example, blow sand out from between paving stones. The heat control of a hot water pressure washer is also implemented differently, and the temperature does not stay boiling hot with sufficient precision.

With the Garden (3 kW) unit, 25 liters of water reaches +100°C in just over an hour. With the Garden (2 kW) unit, 25 liters of water reaches +100°C in under two hours, if the water is taken directly from the tap (initial temperature usually around +4–8°C). You can use the waiting time to do other garden work, read a book, or play with your children.
