Overview
The Diesel Engine Hot Water HP Washer is a professional hot water machine built for use without a connection to the electricity grid. A Yanmar L70V diesel engine drives the pump, and the machine carries a double coil vertical stainless steel boiler with a stainless steel outer casing. The heavy duty tubular steel frame is coated with cataphoresis treatment, which gives it strong corrosion resistance.
This is a true diesel hot water unit: the engine runs on diesel, the burner runs on diesel, and the electrical start is powered by the battery. That makes it a genuine no electricity machine for remote sites, mine sites, farms and anywhere a power point is not available. The constant temperature control keeps the water at a set temperature rather than surging hot and cold.

Frequently Asked Questions
What does cataphoresis coating mean?
Cataphoresis is an electro coating process that gives the steel frame strong corrosion resistance. It is a common treatment on commercial machinery frames that live outdoors, and it protects the frame far better than a simple paint finish.
Why a self priming triplex pump?
The Comet ZWD self priming triplex pump draws water without needing a flooded inlet, which makes setup easier on sites where the water supply is below the machine. Ceramic pistons and a brass head are the durable choices for a pump that runs daily.
Is the boiler certified?
The listing states PED 2014/68/CE category II certification for the boiler. It also carries a safety valve, boiler thermal protection and a flame control kit, so the hot water system is protected against over pressure and burner faults.
