central - east central Minnesota - | deeretech1989 - 5/30/2016 23:37 Would a cold water pressure washer be vulnerable to any damage if fed hot water from a hot water heater? Down at the fire station washing trucks, we use a garden hose that has super hot water, and the whole time we use the hose, (not a constant stream but it's on more than off) it never loses the heat since we got a heck of a water heater. Looking into getting a nice pressure washer for at the station. Don't want a high end heated steamer but if we could get by using a cold water pressure washer fed by the super hot water, that would work well. My only concern is that if feeding it hot water vs cold would cause any issues with seals, pistons, valving, etc. Thanks in advance for any feedback! I suggest doing it correctly - if your fire department has not funds for such . . . work with non-profit fundraising to raise the funds and purchase what you really need. Now - do not get a HIGH Pressure, pressure washer. For that type of washing, 1000 - 1200 psi is all that's needed. Get a higher water volume, lower pressure washer. 6 or 7 gals per min with 1200 psi and hot water, upto 180°F will clean the heck out of stuff. Problem with higher pressure - pressure washers, they cut. Cutting graphics off, can cut into seals and weather stripping and even paint, after repeated uses/passes. Edit for clarity
