Heating Water in Fresh Tank

[Larry B]

Is there a good way to heat water in the fresh tank before it enters the HX's?

 

[floorguy]

DO IT LIKE THE PROCHEMS....

have one go back to the tank....or add one

Little more info on what i'm wanting to try.

I just got another large SG fresh water tank that will run from the side door to the rear doors. On the top of the tank there is a 6" diameter cap that comes off for access to the tank.

If I have a large U-shape ss line bent and put in this cap then put "T's" in the lines to the HX's that reduce down to 1/4" and run 1/4" lines to this new tube in the water tank would that heat the water enough to raise the temp of the water coming out of the HX's ?


p.s. Also would just having the SS line bent so it goes from the top to the bottom and back up be long enough or should it be longer so as to bend the U-shape tube over like a "L" so it also runs the length of the tank?

I have recirculated water through my machine back to the freshy while I set up in a house and do light cleaning under furniture. In about twenty minutes to 1/2 hour you have a hot fresh tank.

the vortex tank had stainless coils running in the bottom of it......it tapped into the radiator and circulated the fluid threw them........as you drove it heated the fresh tank......





















I still don't miss it......

How many gallons?

How many gallons?

100 gallons.

Was there a problem with that? Thats the basic idea of what I am wanting to do but split the heater lines back at the HX's not going to the radiator.

It would also only be 1/4" lines coming out of the 3/8" to get some heat in the tank.

the way that the fresh tank on the Vortex was set up it never gave me any problems.....but......it was not just a matter of hooking up a few lines...some ran threw an HX before it went into the tank and some did not....also the thermostat was taken out of the factory housing and a in line thermostat housing was hooked up so the circulation was a bit different.......this way when it was cold it would not take forever to heat the tank and/or the cab of the truck.........I see no reason as to why it could not be routed threw the heater coil lines ....other then you are going to freeze your ass off in the winter waiting for everything to warm up.........

 

[Larry B]

Think it would work better to install shut off valves and not open them untill the van gets warmed up to normal?

 

[Jim Martin]

you could....but once you get the van heated up and open the valves the cold water around the coils are just going to cool it down.....how much temp loss is hard to say..to many variables....gradual heat up may be your best bet....

I just bought a used SG, I get 240 degree water pretty much instantly, why do you need to pre-heat the water?

I'm not running a propane heater. It's direct drive with 2 HX's

 

[floorguy]

lol get a propane and be done with it

hahaha...theres one in the garage sale ifn i aint mistakin

 

[Larry B]

Nope I'm thinkin if the water is a little bit warmer when it hits the HX,s it will be fine.



Plus this guy below said ya dont need all that heat.

when I was running the vortex in this desert heat...160 was all the fresh tank would give me.in the winter I lost about 20 degrees.....the pre heated fresh tank helped out warming things up...but IMO....the only real use I got out of it was filling my chemical jugs with warm water..........I don't even run with a fresh tank now and I really cant say that I miss it all that much.......

Yeah, so is mine - no propane on the Genie, won't be none either.

 

[Larry B]

At this point I havent got the temp past 170 on the gauge.

if you are talking about while you are cleaning....then a pre heated fresh tank is not really going to help you out any way...........even with the vortex tank and being a pto unit...sitting there running all day it still never got over 160..

 

[sweendogg]

It still boggles my mind why no truckmount manufacture makes an LG or diesel burner PTO machine. No restrictive plumbing for your water pump and blower. No rerouting the vehicles coolant system. Great Heat and Great suck. Hell If it was a diesel burner and utitlized a diesel van say a sprinter, duramax chevy/gmc, or Diesel cabover.. One fuel tank...

I have an owner's manual that says something about a valve you can adjust the heat with on mine.

I was thinking if the fresh water going in to the HX system was warm that the temp on the back side of the HX would be a little higher since the water wasnt so cold going in.

 

[Jim Martin]

all it is going to do is help you get to 170 a bit faster.....

So are the guys claiming 200+ with just HX on a SG just full of shit or how is this getting done?

On my other 47 the gauge shows a little higher heat but still nothing at 200+

 

[Jim Martin]

I am getting 230 to 240 on single wand setting on the thermal wave .....no fresh water tank...the HX is capturing the heat off the blower......

 

[Larry B]

The SG dont use blower heat it's all coolant heat.

 

[Jim Martin]

then you are probably going to be better off taking sweeney's advice and adding a different heater.....a pre heated fresh tank will not help you out as much as you are hoping for.........

 

[Larry B]

What size thermostat should the motor be using?

 

[Jim Martin]

Most run around 190 degree stats
