Hot water improves cleaning efficiency by dissolving grease and oil more effectively than cold water. It also sanitizes surfaces better and speeds up the cleaning process.

Consider factors such as pressure rating (PSI), flow rate (GPM), heating system type (electric or gas), temperature range, fuel type, and the specific cleaning tasks you need to perform.

Regular maintenance includes checking and changing the oil, cleaning or replacing filters, inspecting hoses and nozzles, and ensuring the heating system is functioning correctly. Always follow the manufacturer’s maintenance guidelines.

It depends on the type of fuel used and ventilation. Gas and diesel pressure washers require proper ventilation due to exhaust fumes and are typically used outdoors or in well-ventilated areas. Electric models can be used indoors with proper precautions.

The temperature can vary depending on the model, but most hot water pressure washers can heat water up to 200°F (93°C) or higher.

Nozzles come in various sizes and spray patterns. Choose based on the type of surface you’re cleaning and the nature of the dirt or grime. For example, a wider spray pattern is generally better for larger areas, while a narrow, high-pressure nozzle is suitable for stubborn stains.
