For most household uses, cold or room temperature water in a high pressure washer is sufficient. Our models perform well even with cold water, require little energy, and are easy to maintain. But if you want to increase the cleaning performance, Bosch high pressure washers can be operated with hot water up to 40°C.
Hot water pressure washers, on the other hand, have a built-in boiler that allows them to heat the water up to 155°C. The high temperatures mean both the pressure and the cleaning agents can be reduced.
However, hot water pressure washers can cause burns! What’s more, they are quite expensive. Anyone wanting to buy a hot water, power washer faces high purchase costs, not to mention the huge energy costs in running the device. As such, they are mainly used in the commercial sector.
