The Volcano Hotbox is a diesel fired heat exchanger that connects to your pressure washer and as water circulates around the heater coil, it heats up (the temperature can be set via a thermostat to up to 140 C). The Hotbox is compatible with all pressure washers up to 3000 psi / 200 bar and up to 21 litres per minute (pressure washer is not included).
