The short answer is yes. But this is subjective. The Eco Weedkiller system is extremely efficient compared to other heat systems on the market which use a diesel generator to keep the water at the correct temperature.
The machine uses electricity to heat the water to the desired temperature and then keeps it hot using a specially insulated tank and keeping the water under pressure. This means there is no need to burn fuel all day to keep the water hot.
The electricity used to do the heating could be supplied from any source, including solar energy for example; which makes it possible for the product to be extremely environmentally friendly.
The output of the Eco Weedkiller is simply boiling water, which is very clean and safe fro the environment, and makes it safe to use in many areas where herbicides such as glyphosate are unsuitable or simply undesirable.
