I want to get a diesel fired hot box for my 4000psi 4gpm machine. How do I power the hot box? Do I need to get a generator?
Thanks

If you have a eletric start pw just get a 12v if not then get a 115v and a generator

Hotbox
A 12 Volt hotbox is usually wired into the trailer or vehical and the power comes from the alternator off the engine. A 115 Volt you plug into a generator or an outlet. Usually a cold water machine will not put out enough extra power to keep the battery fully charged while using the hotbox (the charge system keeps up with the machines needs but the hotbox will be trying to draw at the same time) so there is a chance of the battery running low on power. This results in the ignitors not burning hot enough and sooting of the coils is the result over extended use. That's why it's better to wire the hotbox into the trailer or vehical battery and run the vehical while using.

if I am correct the 13 hp or less will not charge enough to keep it all running but a 16 or higher hp will effectivly do the job ?

Try a power invertor (at least 2000 watts) hard wired directly to the battery (i.e) high power amp for car stereo. I've used it with much success. Any questions feel free to give me a call.

I would say get a generator or a long long long extension cord... Remember if you use an extinsion cord make sure it is a heavy duty one.. For a generator //Take your Full Load Amps of the Blower Motor ( Nameplate Rateing) and the name plate rateing on your Ignitor and Transformer add these together and multiply by 120 volts ... Most burners 110v draw at start up anywhere from 400 watts to 1400 watts, As for a 12 volt Hotbox.. You cant get much else out of it... I would do the 120 volt model... IMO... Now another Idea would be to have an extra deep cycle battery mounted into your truck , you will need a switch so the iverter will only use one battery but leave the other one charged... Average running time of a 600 CCA Battery at roughly 1300 watts A/C Draw is around 2.27 hours.. I still theink 120v is the way to go...

All we use are 12v Beckett Burners on our hot boxes.
Russ is right you need at least a 16 hp motor and it has to have a 20 amp + altenator on it.
The engines we use, Briggs 18hp model 350447 come with enough amperage.
Delco sells a ready to go hot box although I dont like the way the wiring is set up.
We haved ours wired to only come on when the trigger is pulled by utilizing a pressure accuated switch, which kicks in a solenoid (constant duty ss type for marine use).
They have theirs set up with a flow type switch and it runs constant ,which will kill your battery.
If you need a wiring diagram let me know and I'll take some photos and sketch something up for you.

Sure you dont have that backwards? Mine is flow actuated and only comes on when trigger is pulled.

I double checked. It's a pressure switch and it kicks in at 580 psi
Terry , How have ya been?

I'm well, I've been working a lot this year since the roundtable. I hope your doing well and look forward to seeing you at 2009 Alabama roundtable.

The heater to which you refer is available with either a pressure switch or a flow switch. In either case the blower motor and ignitor run constantly and the burner only comes on when the trigger is squeezed. This action is provided through the use of the pressure switch or flow switch and a fuel solenoid to interrupt the flow of fuel when the trigger is released.
