Hotsy 843 Hot Water Pressure Washer – 4 GPM, 2000 PSI, 230V 1-Phase, Oil-Fired Heat

The Hotsy 843 Hot Water Pressure Washer is a heavy-duty industrial cleaning machine built for facilities, shops, fleets, manufacturing plants, food processing operations, equipment maintenance departments, and other demanding applications where reliable hot water cleaning power matters.

Delivering up to 4 GPM at 2000 PSI, the Hotsy 843 combines electric pressure-washer operation with a powerful oil-fired heating system. This combination gives operators the cleaning power of hot water without relying on a gasoline engine to drive the pressure washer—making it an excellent solution for fixed facilities and commercial environments with access to 230V single-phase electrical power.

Industrial Hot Water Cleaning Power

Cold water can remove loose dirt, but hot water makes the difference when cleaning grease, oil, hydraulic fluid, heavy grime, and other stubborn contaminants.

The Hotsy 843 uses a high-output 381,000 BTU/hr oil-fired burner to rapidly heat the incoming water, helping detergents work more effectively and allowing operators to tackle difficult industrial cleaning jobs faster.

For businesses that clean every day, that can mean less time spent fighting grease and more productive cleaning per shift.

Slow-Speed 1725 RPM Motor Built for Long Service Life

At the heart of the Hotsy 843 is a heavy-duty 5 HP, 230V single-phase electric motor operating at just 1725 RPM.

The slow-speed motor works with Hotsy's belt-drive pump system to provide smooth, dependable operation while reducing the high-speed wear associated with lighter-duty pressure washer designs.

This makes the 843 especially well suited for businesses that need a pressure washer for frequent or continuous commercial and industrial use.

Belt-Drive Hotsy Triplex Pump

The Hotsy 843 utilizes a rugged crankshaft-style triplex pump with a belt-drive system designed for demanding professional applications.

Rather than building this machine around maximum advertised PSI alone, Hotsy combines approximately 4 GPM of water flow with 2000 PSI working pressure, providing an excellent balance for washing equipment, vehicles, machinery, floors, production areas, and other heavily contaminated surfaces.

Built for Real Industrial Environments

The Hotsy 843 isn't a lightweight consumer pressure washer dressed up for commercial use.

Its rugged steel cabinet and industrial chassis are designed around everyday professional operation. At only approximately 28 inches wide, the machine can maneuver through many standard commercial doorways while still providing the durability expected from a full-size Hotsy hot water pressure washer.

Solid rubber tires, front swivel casters, and integrated forklift slots make positioning and transporting this substantial machine easier around warehouses, service facilities, plants, and maintenance departments.

An integrated float tank helps maintain consistent water supply to the pump while providing additional protection for the pressure washer's internal water system.
