Russ,
Do you think the heat had a dramatic effect on the cleaning result?

Hi Ash

Who knows? all i can say is that all the time the Airflex is truck mounted i can use the zeta which means i have temperature control from 0 - 90deg C and i am using the pump on the zeta which is designed to run at up to 1750 psi thus saving wear and tear on the airflex.
And i haven't got to bugger about with inline electric heaters

How many power leads did you run

Hopefully I'll be running a Propane water heater as of tomorrow... Providing the thing turns up...

Nice thinking outside the box ...
can you get the pressure lower than 500
was the zeta the lowest priced diesel heat exchanger washer you came across ...

colin day ...  Little giant ?
wondered why they are not used more over here ... is  bottled propane expensive here compared to the states perhaps ?

The stuff ain't cheap. I have static caravans which use the stuff and lately it's been around £35 for the 19kg bottle

You can lower the pressure as low as 250 psi, really depends on what jets you have on your wand, the zeta is really nice because its compact and it can run on diesel, bio diesel, heating oil.
i run two extension leads:

The first runs vacs 1 and 2
the second runs the zeta and vac 3

Plus... it costs about £1000, now thats a grand for a really good pump which will out perform and last longer than most pumps in a portable, and you get a very efficient heat exchanger.
Plus... you can use it for washing your van... steam cleaning engines... hard surface cleaning... its pretty versatile!

I have now included some pics just to show how i have installed the machines into my van, its a project which is no way finished but it works...

Didn't turn up

I'm not sure how much gas it'll guzzle to be honest.

I like the idea of the Zeta.

Hi Colin

Check this out...

The Zeta has a 5ltr fuel tank and uses approx 3 ltrs of diesel per hour, that's running the burner constantly for an hour which is impossible due to the thermostat cutting out at 90 deg C.
With using propane your running costs will almost certainly be higher, plus you are still using your portables pump system.

How much is the propane system? The Zeta is £899.99 + VAT and that comes with a hose and lance for washing the van!

My machine runs on red diesel, bio diesel, heating oil, paraffin.....

Nice set up.

Makes an excellent weeder that!

On the zeta ... if you are set to minimum pressure/flow
you have dual output connections ... if you fit a regulator to one side with a hose flowing  back to the water tank ... and connect the wand to the other output , would that allow you to adjust pressure below 250 ...    ??

I have duel outputs for exactly that purpose, you can crack open the output valve so you can return hot water back to the tank.you can also use this to fill your pump sprayers with hotwater which is handy if using powdered pre spray chemicals.
You only need to bleed off a little to lower the pressure to 250 psi... ideal for cleaning upholstery.

The Zeta has a flow switch which activates the diesel solenoid, if there isnt enough output flow the burner wont fire up.

This return pipe to the water tank is the best way to lower the pressure and still have the burner working.
There is a possibility that the flow switch may have some adjustment... will look into that.

john yes, but you would be preheating the water..... which after a while would become to hot for the pump, but that's what i do to control the psi and heat spikes with my heater.

Russ alter the position of the regulator to 45degrees instead of vertical

Hi Mike

As you can see i am not returning water back to the tank for this demo so the regulator wasn't in operation as i would be quite happy to use the wand at 450 psi for carpets.
Like i said i will be looking at adjusting the flow switch on the machine so i can get lower pressures with heat.

Having a second output is dead handy for hot running water !
