Burner Question

Hello, What I am wanting to do is be able to use my 8gpm 3000psi Pressure Pro cold water machine with the hot water boiler of my
Hotsy 1295SS 5.6gpm 3000psi 12 Volt hot water skid.

I would put a plug/coupler on the hoses going in/out of the coil so switching from machines would be just 2 hoses, that is the easy part.

Since the Hotsy has a pressure/flow switch right on the outlet of the pump (red "T" shaped box with wire) and the adjustable thermostat with on/off switch and hour meter are on the Hotsy unit right by the pump I am thinking that it might be easier with a second thermostat controller box, flow/pressure switch, etc.... all wired up to the 8gpm pressure pro unit. The Pressure Pro did come with a 20 amp charging circuit so that part probably will not be a problem.

I am thinking that I would have to splice into the wiring from the Hotsy Control box to the burner and put "T"'s on the wiring there so you could run either control box or cut into the wiring at the burner so I can have a separate controller for the burner.

Just wondering if this has/can be done so I can use either machine with the burner. I know the wate will not get as hot with 8gpm running through it but warm water will work on some of these jobs.

Thank You.
 
Just wire up the flow switch to the burner (after the inlet from pump)so it is basically all self contained like a stand alone unit and you will be fine. A second setup will cause you to have to rewire a bunch of it every time if I understand what you are doing.

Paul, is it possible that he could change out the fuel nozzle to beef up the heater so it could handle 8 gpm's?


I thought I read somewhere that could be done. I think it was the fuel nozzle or something inside the heater could be changed to burn the higher flow efficiently.
 
The 8gpm system has a 20 amp charging circuit but the power to the burner comes from the battery that is on the Hotsy skid, that might be a problem unless I buy longer battery cables and run the 8gpm machine from the battery in the hotsy skid?

If I do that and..... move the switch to where it is inline at the coil then would that work?
 
Another thing is would the key or power need to be on at the Hotsy skid for this to work?
 
You'd have to do some MAJOR rewiring. The Hotsy engine would have to be running for the burner to work. There's a bridge rectifier and a relay in the controls that require power from the engine to function.
 
Yes that is a lot of rewiring I thought you wanted to make it a stand alone heater that you could plug into either and they were right next to each other.

You could up size the burner nozzle ant is would help but you will not likely get enough heat rise for 8 gpm.
 
Thanks for the info and help guys, I thought it might be an easy fix but that is ok, I don't want do mess with all that stuff. I will just get a hot box for the 8gpm unit later on when I have the money.

What is the max heat rise you could possibly get by up sizing the nozzles. or how much flow could it accommodate?

The 120v would make it much more convienent!........, Would I couple the cold water machine (with or without an unloader), before the micro switched unloader of the existing hotwater machine?

"Tee" the units off with ball valves

Travis that depends on the burner installed on the unit. Beckett and Wayne both make small and large frame burner housings. On the large frame, you could go as high as 3.5 gph with the large squirrel cage fan. The small frames are going to limit you on fan size.
 
Respect the tech ! ...
there's a lot you guys need to now about messing with heater adjustments !!
Don't go in there without an "education". ...:nono:
air adjustments, fuel pressure, nozzle spray-patterns, the shape n' size of the burner chamber,
and as Russ pointed out.. burner size is an issue too.

on the flip-side of the coin..
If you're not afraid of doing some re-wiring,
adding an upgrde on that Hotsy will make the ignitors last longer.
e-mal me for free info.
