hi all,
i wanna learn how all the parts on a truckmount work before i make up my mind on which one i wanna buy.so how does the heat exchanger work?i like simple machines,not over engineered.please post pics of simple machines as well.also if you build your own truckmount how could you set up a kero heater?

HX are either coolant or exhaust heated. Some machines have both.

On a coolant HX the water is heated from the coolant from the engine. On an exhaust HX the water is heated by the exhaust from the engine. My Performer has three HXs on it - 1 on the blower exhaust, 1 on the engine coolant (heli-coil) and 1 on the engine exhaust. My PC has a coolant and exhaust as well.

Imho; Don't use heat exchangers. Use oil or Propane fired heaters downline from the pump. My kero heater can make 400 degree water for pressure washing; or 275 degree hot water to clean effortlessly Chineese Restaurant carpet. I do recommend to change hoses if you use kero or anything larger than a 2ht propane.

Some units use heat from the exhaust from the engine, heat from the Coolant of the engine, and from the heat (pressure) made from the Vacuum motor Or all three (fancier models) the water is run through a exchanger radiator or metal spool/coil made of cooper tubing or stainless steel (fancier) there is a exchange of heat from a hot soure to a cooler source and since heat is attracted to cold you get a heat transfer. Hot will always be attracted to cold temperatures. you dont get things cold you take away heat .

Simply put an heat exchanger lets heat from one source transfer heat to something else.

Example:

Gas fire heats metal that then heat the air going over it = your house heats up.

Hot water passes through very narrow channels that air is passing by fast = auto radiator cools the water that cools the engine.

Your engine heat passes past metal that takes much of the heat away - this heats water that is on the other side of the metal. This heated water is then used to clean carpet! = HX w/ heat from an exhaust ! This is used for the blower exhaust as well.

So for CC the heat from one source is given off to another. These is must often done with three parts. 1st - the heat source. 2nd an item absorbs the heat (the HX) 3rd - is that which absorbs the heat.

In CC ex. are

1st - Exhaust that is hot (Blower or the engine)
2nd - Must often is Metal tubing absorbs the heat.
3rd - Water in the tubing absorbs the heat from the tubing. Water is the pumped down the solution line to the wand!

I agree with Rickie Fontenot - but you are on the right track to know the machines and then make YOUR informed choice.

so on your recoil porty you have kero heat after the pump?do you keep the kero in the van or do you ahve to take it out of the van?you would still have to leave the porty outside because of the kero gas right?how long of hose run can you get if you leave it outside?
