Buying Guide: Hot Water Pressure Washer Add-Ons
Key considerations help determine which heater-add-on is right for you. Start by matching heat capability to the grime you encounter most often, then weigh fuel availability, electrical access, and mobility.
- Heat Temperature: Higher temperatures melt grease faster but may require more fuel and careful handling. Units offering 194–212°F are typically versatile for many industrial tasks; check if you need steam as well as hot water.
- Power Source: Gas (propane or gasoline) models excel in mobility and heat-on-demand, while electric models simplify operation in enclosed spaces but rely on available outlets.
- Pump Type: Triplex pumps are common on heavy-duty units for durability; direct-drive pumps can be lightweight but may wear faster under high pressure. Consider the expected workload and maintenance availability.
- Portability and Setup: Gas-powered systems are heavier but offer true mobility. Electric units are easier to start and operate in controlled environments.
- Safety and Ventilation: Hot water and steam require careful handling. Ensure proper ventilation when using gas heat and follow all safety guidelines for high-temperature cleaning.
