Karcher HWE 860 Booster Heater | 3.070-030.0

Introducing the Karcher HWE 860 Booster Heater, a powerful addition to your cold water pressure washer, designed to significantly enhance its cleaning capabilities through the power of hot water. This robust inline heater features an emission-free electrically heated boiler system, making it an excellent choice for indoor environments such as production and manufacturing facilities where maintaining air quality is essential.

The Karcher HWE 860 boasts a substantial internal boiler capacity of 55 litres. This allows for an initial cleaning phase with water heated up to an impressive 85° C, providing the necessary power to tackle even the most stubborn and ingrained soiling. This initial high-temperature burst is ideal for areas with heavy contamination.

Once the initial 55-litre volume of high-temperature water is utilised, the Karcher HWE 860 continues to deliver a consistent supply of hot water. The powerful electric heating element ensures a continuous hot water flow of up to 51° C when operating at flow rates of up to 700 litres per hour. This sustained heat output provides ongoing cleaning effectiveness for larger areas or prolonged tasks. It is important to note that the continuous output temperature may gradually decrease if the water flow rate exceeds 700 litres per hour.

Engineered for seamless integration with compatible Karcher cold water pressure washers, the HWE 860 unlocks a new level of cleaning performance. The emission-free electric heating system makes it particularly suitable for indoor use in factories, workshops, food processing plants, and similar enclosed spaces where exhaust fumes from combustion-based heaters would be unacceptable.

By investing in the Karcher HWE 860 Booster Heater, you can maximise the potential of your pressure washer, achieving superior cleaning results indoors. The combination of a significant initial volume of very hot water and a capable continuous flow of heated water ensures effective and efficient removal of grease, oil, and persistent grime, all within a clean and emission-free operating environment.
