Landa's EHW hot water pressure washer creates instant hot water spray without an open flame or hazardous fumes. The unit runs quietly. Two models range in cleaning power from 3.5 to 4.2 gpm and from 2,000 to 3,000 psi of pressure. Both models operate on 460-volt, three-phase electrical power. The company backs the washers with a seven-year warranty.
