But it’s getting that trade price that’s the problem!

[P @ F]

I built what I built as I’m governed by weight and power needs of the 9kw , I could have gone with the thermotop c , but again I am getting the same results if not better from my China special , plus I know it inside out having built it myself

I purchased the kit myself it was just over 1000 you need a cabinet yes really but that’s how much you can get the kit for.
We used to joke that other suppliers are charging 2500 for a cabinet.

[dazmond]

Dont forget you ve got a metal cabinet, 2 decent batteries and boxes,smart split charge relay kit and electronic unit,a commercial battery charger,a digital controller with frost stat on top of that.......plus fitting and the extra bits needed to integrate into the fuel sender on top of your vans diesel tank......then theres the fitting and labour costs(drilling through the van floor for the exhaust and vent pipes.etc)..also £750 of the 4.5k I paid was VAT!

[NWH]

If you buy a heater in a cabinet fitted from a few companies that supply them you are paying for that alone,you don’t get a split charge relay and 2 batteries with it you have to pay for them.
Anyone wishing to go hot will more often than not have all of what you mentioned but maybe they’ll only have the 1 battery,they will only have to purchase the kit from Webasto and either a Grippa controller or one from stream which is called a frost stat controller,I purchased this kit so I know you can buy it for that price.

[P @ F]

And that is what puts people off doing it themselves !

[NWH]

If you can get a cabinet and you are half decent a DIY it’s not that hard to do.

if its that easy nigel why did you go for a professionally fitted system then?

[NWH]

I wanted a 9kw for 1 I wanted to spend some money on equipment for 2 and I got fed up with the smell of diesel from using a separate tank inside the van.

How about this?

That is good !
Thing is how many would you need for a 350 tank , and what ampage does a single glow plug draw ?

Pending on the ampage and time taken to heat given litres of water, might be interesting.   Use a 50ltr draw tank from main tank and have several dotted about in the tank to give a good mix.
 
Or not

You would be talking around 13amps per 150w glow plug,

[P @ F]

So you would need a few batteries then

Now I can get some real results , this is for the temp as it enters the reel

[KS Cleaning]

Now I can get some real results , this is for the temp as it enters the reel

Better getting the temp when it leaves the reel😜

[P @ F]

Yes but that is easily done with the TDS meter , what I wanted was to get the water temp during real use , as I was doing it I was opening up a valve within the middle of the system which changed pressures and flow rates .
I plan to get bottom of tank temp and entry to reel temp , in fact I could get a few others too !

[P @ F]

Now where shall I put these 

[P @ F]

As I thought , different pressure and flow rates give higher temps .
This is with the water diverting straight back to tank

[P @ F]

And this is with the pole in normal use , more restrictions give an extra 5 Celsius!
