What is the difference between 2 kW and 3 kW Eco Weedkiller Garden hot water devices?

  • heating time
  • Device: Garden
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.
