Hot Water Setup

[flamesagent]

Question: I have a cold water pressure washer. The water flow is: Water Tank->Water Pump->Pressure Washer. Between the Water Pump and the Pressure Washer (Subaru 3100psi) I am thinking I can install some form of hot water heater in order to deliver hot/warm water to the pressure washer for output. Trouble is, I am not sure if this can be done and, if it can be done effectively, what type of outdoor water heater could I use (money is a factor). The application is for commercial mobile detailing... not for home use.

Any guidance you could give would be greatly appreciated. Thank you.

I'm looking at one of these for doing washes with hot water. might work fine for your application also.

You can add for 1000 or more.Hotsy is a good brand.Expect lots of trouble with hoses bursting. Had one for 5 years and paid 6k for one mounted in a van.

Hate to be negative but for 116.00 don't think it will do the job.Hot boxes run on diesel fuel.

Thank you, everyone, for your responses...

Kb2ehj, I did look at the water heater for the link you provided. The problem I am having is that the tankless water heaters, that can run within 30 Amps, have a low flow rate (somewhere around 1.0 GPM) but the pressure washer operates at 2.4 GPM... as I understand it, that only equates to maybe a 20% rise in water temperature on the output. Kind of pointless.

I started looking into pressure water units with heated water and, OMG, I could not believe the pricing... it's huge.

Not quite sure which way to go at this point.
