 | Tests have proven that Kärcher Classic hot water pressure washers use 25+% less fuel than standard models—thanks to these exclusive design features:1: Heat is both absorbed and 'bounced' off a firebrick floor retaining the heat longer in the heating chamber; 2: A double-pass coil forces water to pass through the heating chamber twice for added heat-transfer efficiency; 3: Outside air serves as an insulation blanket and is pre-heated prior to being injected into the flame for optimum combustion. |
