Thanks to the efficient burner technology with 43 kW heat output, our HG 43 water heater can transform all high-pressure cleaners into efficient hot water cleaners.
The cost-effective solution for upgrading existing cold water cleaners: our HG 43 hot water heater is compatible with all high-pressure cleaners on the market, regardless of whether they are Kärcher machines or not. Age and performance are irrelevant here. Using hot water for high-pressure cleaning saves on cleaning agents, significantly increases the cleaning speed and improves cleaning results, especially when removing greasy and oily dirt and deposits. In addition, the working pressure can be reduced to protect sensitive surfaces while maintaining the same cleaning performance. The technically advanced burner technology with 43 kW output ensures high efficiency with low emission values. Our proven safety technology with safety block with pressure switch, water shortage protection and integrated Soft Damping System to protect the heating coil from vibrations ensures a long service life. All machine components are designed for long-term use, while a stable tube frame also enables use under tougher conditions.
