- 3 kW Device: Heats 25 litres of water (from 4°C to 100°C) in 1 to 1.5 hours. It requires a heavy-duty 15-amp power supply, making it ideal for larger New Zealand lifestyle blocks or commercial landscaping.
- 2 kW Device: Takes 1.5 to 2 hours to heat the same amount of water. It is tailored for standard residential gardens and plugs safely into any standard New Zealand 10-amp household wall outlet.
Yes, absolutely. Eco Weedkiller relies entirely on pure, regular water heated to a precise 100°C to eliminate invasive weeds. There are absolutely no added chemicals, toxic glyphosates, or chemical surfactants. This makes it a 100% natural, chemical-free weed control solution that perfectly protects your garden soil, native New Zealand plants, and local ecosystem.
You will know the application is successful by a few distinct, immediate signs:
1. Wilting foliage: The targeted weeds will instantly begin to droop and wilt as the cellular walls collapse from the thermal shock.
2. Sizzling sound & steam: You will hear a characteristic sizzling sound from the nozzle, and steam will rise gently from the treated soil zone.
3. The “cooked organic” aroma: A distinct, natural scent of boiled vegetation will briefly fill the air around the application site
For standard seasonal maintenance, we recommend treating your problem areas 2 to 4 times per growing season depending on weed density. While the 100°C water penetrates deep to destroy existing root zones, tough or deeply established invasive species may require a fast follow-up application. Over time, consistent thermal treatment completely exhausts the weed seed bank in the soil, meaning you will need to spray less and less each year.
You can use standard, clean tap water straight from your regular garden hose or outdoor tap. Because our systems heat the water to a precise 100°C, it is best to use clean water free from heavy debris, sand, or grit to ensure optimal performance and protect the internal components. There is no need for specialized distilled or filtered water—standard New Zealand town supply or clean rainwater tank water works perfectly.
The volume of water required depends entirely on the size and density of the weed growth you are treating. Our standard Eco Weedkiller home unit holds 25 litres of water per tank. On average, a single 25-litre tank gives you roughly 20 to 25 minutes of continuous treatment time, which is plenty of capacity to clear regular household driveways, gravel paths, patio pavers, and garden borders.
Eco Weedkiller is highly effective against a broad range of common New Zealand weeds, invasive grasses, and stubborn moss. It easily eliminates property invaders like clover, dandelions, plantain, chickweed, thistles, mallow, and docks. Because the 100°C water delivers instant thermal shock, it is perfect for safely clearing unwanted growth out from gravel driveways, cobblestones, pathways, and garden borders.
Yes, absolutely. Unlike manual weeding or line trimming which only removes surface growth, the 100°C water acts as a powerful thermal conductor. It travels straight down the plant stem and saturates the soil to cook the root cells entirely. By destroying the root zone, the weed is unable to absorb nutrients or photosynthesise, successfully killing the plant permanently from the inside out.
No, standard pressure washers or steam cleaners cannot achieve the same permanent results. While steam might look hot, it loses its thermal energy the instant it leaves the nozzle and hits the cold air, only killing the surface leaves. Pressure washers can also blast away paving sand and damage grout. Eco Weedkiller works by delivering a high volume of steady, solid 100°C liquid water directly into the ground, ensuring the heat stays hot enough long enough to fully cook and destroy the root system.
No, standard pressure washers are not designed for effective weed control and can actually cause property damage. Most pressure washers use cold or lukewarm water, which only blasts away the top of the weed while leaving the root system completely intact to grow back. Furthermore, high-pressure water can erode asphalt, crack aged mortar, and blast out the jointing sand between your paving stones. Eco Weedkiller uses low-pressure, solid 100°C liquid water that gently saturates the soil to cook the roots without damaging your hard landscaping or surfaces.
- The heating time depends on the specific model you choose and your initial water temperature:
- 3 kW Unit: Takes approximately 1 to 1.5 hours to heat a full 25-litre tank from cold tap water to the required 100°C.
- 2 kW Unit: Takes approximately 1.5 to 2 hours to heat the same volume of water.
