Frequently asked questions
The Eco Weedkiller products utilize hot water to eliminate weeds by targeting chloroplasts within the leaves. When exposed to temperatures above approximately 76 degrees Celsius, these cells, responsible for photosynthesis, burst or congeal. This process prevents the plant from converting light into energy, effectively starving it. The plant typically dies within 72 hours, with the effects of the heat treatment often visible within minutes of application.
Eco Weedkiller technology heats water using electricity and then maintains its warmth in an insulated tank. The device can keep the water at over 100 degrees Celsius for at least eight hours after being disconnected from the power supply. This design allows for use without continuous connection to an electricity network or water supply, providing mobility for weed treatment in various locations.
Yes, Eco Weedkiller systems are considered environmentally friendly, particularly when compared to other heat systems that continuously burn fuel. These machines heat water electrically and maintain its temperature using an insulated, pressurized tank, eliminating the need for constant fuel combustion. The electricity can come from renewable sources like solar, and the output is simply boiling water, making it safe for environments where chemical herbicides are undesirable.
Find out more about Weed Prevention strategies hereEco Weedkiller products, using hot water for weed control, are effective in a wider range of weather conditions than chemical alternatives. The hot water is not subject to drift like chemicals, allowing for use in moderately windy conditions if safely controlled. While effective in rain, very cold weather might require more water for optimal results. This versatility makes it a reliable tool for year-round weed management.
Since the product delivers water at over 100 degrees Celsius, there is a potential risk of deforming thin plastics or causing scalding if it contacts skin. It is crucial to conduct a risk assessment for all application areas to minimize or mitigate these risks. Despite these considerations, these products have been safely used on various ancient and modern surfaces without incident.
No, you do not need a licence to use hot water to kill weeds.
The Eco Weedkiller products are virtually silent in operation. There is no engine, so all you hear is the water funning onto the surface and a small hiss, indicating it is at the correct temperature (over 100 degrees Celsius).
There are versions with a 300 litre and 600 litre storage tanks as well as a small Garden version with a 25 litre water tank. Using water allows great penetration into the soil, allowing successful treatment of perennial plants with more established root systems in many situations. The rule of thumb is that 2–2.5 litres of hot water is needed per square metre in areas with 100% greenery coverage. This means that 300 litres of water is enough for 100–150 green square metres.
Notes. Prior to heat weed control solutions it is recommended all sites are cleared of detritus.
The trigger must be pulled in order to deliver the hot water. So the machine cannot use hot water accidentally. However, there is a filling mode, a heating mode and a working mode, which must be correctly selected so that the correct task can be carried out by the machine.
