Twin tanking - Peugeot Boxer 350 LWB 2.5D - Minibus/camper/van

gm pipework was wrong hers a new one!

[greasemonkey]

With the updated pic, I think when you turn the tap on, it can still pull air from the return pipe. Follow it back from the tap, through the pump, and up through the HE.

I think the amount of water your heating, if you covered the bottom of the tank, with like a grid of pipes, it would heat almost as quickly as the coolant.

Seen the new one now. Cant see why that wouldn't work.

Thinking further, I wouldn't be happy bringing the coolant back that far from the syatem, so why not have the HE under the bonnet, and bring two pipes back, into a coil in the water tank. Then you need a pressure release in the system......................

what you dont know or didnt notice is on the right side of the blue tank in van (other side plywood) are 2x coolant pipes to an extra heater the van come with, its sat between driver seat and passenger seat, so easy to TEE off them and its only say 6 inches from plywoood. drill 2 holes and pipes are in!

 

[greasemonkey]

Well thats mighty handy. Is there something already fitted to control the flow in the pipes, or was it in the heater unit?
Its simple to plumb an HE in, in that case, and go with what you've got in the pic. At least with the HE, you haven't got the issue of pressure in the hater tank heating circuit.

not sure if water through that heater in cab is constant or controlled by unit? i got a switch on dash to turn fan on in the unit to circulate, the pipes both get warm if i remeber? will check it out.

need to buy an essex flange in about 15mm compression as i cant get inside that blue tank to add the heated water back into tank now...

[Rotary-Motion]

could this REALLY? be puished through a hole in a tank with no need to enter into tank? looks odd

and what is the wire for?

Yes it can, I fitted and immersion boss to my reactor like that one (just bigger).
The wire is so you don't drop anything inside the tank when you fit it.

The metal piece of the washer that goes into the tank is split, so you fold it to get it into the hole.  Not that i know any thing about it, but I had a sneaky google when you mentioned them, just so I look like I do

Heck of a price on them. Anywhere from £16 to £24.

[Rotary-Motion]

hmm bit expensive but i need one

shame bes ones are £5 but min order 50 quid isnt it?

[Rotary-Motion]

what temp could my blue water tank take? if useing the above system of engine coolant heated water/tank potentially it could go 80/90c ?

would the blue tank take this, im GUESSING! its HDPE type plastic, it did come out a camper,

[Head Womble]

It may have come out of a camper but it was probably only for cold water storage.
If it is HDPE it may have a max temp written on it.

did have a quick look, couldnt see anything...

HDPE - WIKI page = http://en.wikipedia.org/wiki/High-density_polyethylene

says 120c for short periods, BUT! been reading different pages via the net and some say as low as 65c

i have been given a 12v emertion heater element from kieth (K.H) for testing, not really looked at it yet but not sure if it has a stat in it.... or what wattage it performs at...

update...

got me a dead man switch in the system now (dont want camper part live all the time) from the split charging second battery i fitted under the drivers seat, with 27amp cables going to the new control panel door / bay compartment, also cut some doors out where cupboards are, and i measured it up so if i do get a fridge later the biggest door can be cut out for a fridge  that relay in the pics is a 250 amp jobby, there is a button on the dash control panel if pushed links both batts for cold cranking (or winch useing on 4x4's)

also got a new sink im well happy with that came out an old VW camper, bang tidy with a drainer  thx K.H. i got some goodies for you too bringing them to work today! 

and 240 sockets came out the scrap pile at chugs BBB, sockets for 240 hookup or genny powered (not inverter, be separate bit) thx chug 

and leisure battery courtesy of GM greasemonkey's buddy, cheers chap
