These powerful machines cut through the toughest industrial messes with ease, saving you valuable time and effort on any job site. Whether you need the rugged mobility of a diesel hot water pressure washer for remote work or the consistent power of an electric hot water pressure washer for workshop tasks, we have the right model to boost your cleaning efficiency and deliver substantial results.

FAQs

Common questions answered.

Five of the questions we hear most often on carpark and street linemarking gear. Full knowledge base on our FAQ page.

  • When do I need hot water?

    When the work has oil, grease, animal fat, food residue, carbon or biofilm bonded to the surface. Workshop floors, food processing, transport depots, kitchens, marina + boat wash all need hot water. Cold water washes loose dirt off but leaves the oil/grease bonded. Hot water (typically 60-90 deg C output) breaks the bond and lifts both at once.

  • Explorer G2 (petrol) or Explorer G2d (diesel)?

    G2 has a Honda GX petrol engine driving the pump + a separate diesel burner for water heat. G2d has a diesel engine driving both pump and burner from one fuel tank. Pick G2d when the site already runs diesel for other plant (consolidates fuel storage) or where the customer wants single-fuel operation. G2 is fine where petrol + diesel storage is already in place.

  • Hybrid + Hynox: when?

    Jetwave Hybrid and Hynox are electric-drive + diesel-burner. Electric drives the pump; diesel heats the water. Right for indoor work where engine exhaust isn't acceptable but hot water is still needed - food processing, kitchen, indoor workshop. Hybrid 275-20 is 4000 PSI x 20 L/min; Hybrid 200-21 is 3000 PSI x 21 L/min.

  • Burner maintenance?

    Annual at minimum. Clean and inspect heat exchanger, replace burner nozzle if worn, check fuel pump pressure. Skipping burner service results in soot build-up that reduces heat output and eventually clogs the heat exchanger - a major repair. Pump side follows standard triplex service (oil change, seal/valve check, packing replacement on schedule).

  • How do I maintain hot water pressure washers for long service life?

    After each use, flush clean water through the system and wipe down external surfaces. Inspect hoses, fittings and o-rings for wear or cracking before each use. Change pump oil per the OEM schedule (typically every 50-100 hours for petrol units). Store indoors or under cover to prevent UV degradation of hoses and seals. For seasonal storage, run a pump-saver solution through the system to prevent mineral buildup and corrosion. Replace worn nozzles before they affect spray pattern — a worn nozzle increases water consumption and reduces cleaning efficiency.

Hot Water Pressure Washers

7 hot-water units - Jetwave Explorer G2 + Explorer G2d (diesel-engine), Hybrid (electric-drive + diesel burner), Hynox (electric-drive + diesel burner). Hot-water units run a diesel-fired burner that heats the pump output - the heat breaks the bond on oil, grease, food residue and stubborn carbon that cold water cannot shift.

When you need hot water. Workshop floors with engine oil, grease, hydraulic fluid. Food processing facilities with animal fat, dairy residue, blood. Transport depots with engine grease, road grime, fuel spills. Kitchens with cooking oil residue. Marina and boat wash with marine biofouling and oil. Cold water on these surfaces washes the loose dirt off but leaves the oil/grease bonded; hot water breaks the bond and lifts both at once.

Explorer G2 vs Explorer G2d. Explorer G2 is the petrol-engine hot-water unit (Honda GX engine drives the pump, diesel burner heats the water). Explorer G2d is the diesel-engine variant - diesel drives both pump and burner from one fuel tank. Right pick for sites already running diesel for other plant where consolidating fuel storage matters. Both come in 280 (4060 PSI x 13-15 L/min) and 210 (3150 PSI x 15 L/min) spec.

Hybrid + Hynox. Jetwave Hybrid and Hynox are electric-drive + diesel-burner hot-water units. Electric drives the pump (mains 230V or 415V three-phase depending on spec); diesel heats the water. Right for indoor work where engine exhaust isn't acceptable but the work still needs hot water - food processing, kitchen, indoor workshop. Hybrid 275-20 is 4000 PSI x 20 L/min; Hybrid 200-21 is 3000 PSI x 21 L/min; Hynox 200 is 3000 PSI commercial spec.

Burner fuel + service. All hot-water units use diesel for the burner. Burner service is annual at minimum - clean and inspect heat exchanger, replace nozzle if worn, check fuel pump pressure. Skipping burner service results in soot build-up that reduces heat output and eventually clogs the heat exchanger - a major repair. The pump side follows standard triplex service (oil, seals, valves).
