Abstract

This innovative, top-quality product ensures a fully operational device that will benefit all individuals interested in a cost effective means to convert a cold water pressure washer into a hot water pressure washer. Thus the user will have the full benefit of the cleaning capabilities of both a hot water pressure washer and a cold water pressure washer.

Claims (14)

1 . A pressure water heater comprising:

a tankless water heater having an ambient water input and a hot water output and mounted to a frame of a pressure washer wherein the hot water output is connected to the pressure washer input and a pressurized water output of the pressure washer comprises a pressurized hot water; and

a hybrid electric and an LP gas tankless water heater pair comprising the ambient water input and the hot water output for the tankless water heater.

2 . The pressure water heater of claim 1 , wherein a power for the tankless water heater and the pressure washer is supplied by a DC battery mounted via a shelf on the frame of the pressure washer.

3 . The pressure water heater of claim 1 , wherein the tankless water heater is an LP water heater and a power for the tankless water heater is supplied by an LP gas tank.

4 . The pressure water heater of claim 1 , wherein a power for the tankless water heater and the pressure washer is supplied by a 120V/240V power cord with a GFI (ground fault interrupter) circuit adjacent thereto.

5 . The pressure water heater of claim 1 , wherein the LP tankless water heater and the electric tankless water heater pair are connected in a serial water flow and powered by a respective LP gas tank and a DC battery source.

6 . The pressure water heater of claim 1 , wherein the LP tankless water heater and the electric tankless water heater pair are connected in a parallel water flow and powered by a respective LP gas tank and an electric source.

7 . The pressure water heater of claim 1 , wherein a temperature setting for the hot water is determined by a preheater first tankless water heater and a second stage second tankless water heater acting in tandem.

8 . The pressure water heater of claim 1 , wherein the tankless water heater is mounted to the frame of the pressure water heater via a plurality of self tapping screws.

9 . The pressure water heater of claim 1 , wherein the LP tankless water heater is vented to a height greater than 7 feet from surface via a pipe connected to an exhaust of the LP tankless water heater.

10 . The pressure water heater of claim 1 , wherein a tandem arrangement of the hybrid electric and the LP gas tankless water heater pair comprises a common ambient water input and a common hot water output.

11 . The pressure water heater of claim 1 , further comprising a common hose bib connection between a garden hose water input and the tankless ambient water input.

12 . The pressure water heater of claim 1 , wherein the tankless water heater is mounted to the pressure washer frame via a plurality of “L” brackets.
