WATER IS WATER, ISN'T IT?
Steam and hot air do not work in the same way as hot water at all:
- Water is one of nature’s best energy transmitters and hot air is one of the worst.
- Gravity means that the water flows downwards and reaches the plant quickly, right down to the roots.
- Hot air and steam always rise , so some of the energy (heat) disappears before it gets to the plant.
The Heatweed Method fully exploits the properties of water: Combined with sensor technology and advanced temperature control, this results in a means of controlling weeds that requires very little energy. Thanks to efficient energy transfer, a maximum of four applications a year will suffice.
A study carried out at the University of Copenhagen shows that treatment with hot water produces the lowest weed cover – even with the lowest treatment frequency. See the below table:
Above: Hot water can transfer 23-27 times more energy than hot air or steam. Here you can see pictures from studies at Ghent University 7 days and 21 days after application.

There are advantages and disadvantages to most methods. The Heatweed Method is a just choice.
