Heatwave® Thermo 2
Diesel-fired Heatwave® Thermo 2 water heater for two operators — fitted in Ultimate window-cleaning and pressure-washing van systems.

Hot water cleans better than cold water. A Streamline® Heatwave® water heater reduces cleaning times, as hot water cuts through dirt, snail trails, fly spots and spider webs more easily than cold water.
Heatwave® systems use diesel from the vehicle’s fuel tank or a separate remote tank that can be filled with red diesel for economy. The Thermo 2 can be retrofitted to a pure-water system.
