24 volt propex

[Donald360]

I noticed a 24 volt propex heater on fleabay. Is it possible (or desirable) to convert my van's 12v to 24v so that i could use this versin of the propex?

you could link two batteries in series (or is it parallel ) to give you 24 volts

Yup that's how most of the army trucks are set up for

Possible to connect 2 batteries in series to get 24V, but you would need to parallel charge them,
I wouldnt consider converting Starter, Lights, Alternator, Fans, etc to 24V.
So unless you are good at electrickery, and fancy a control pannel from a Sci Fi film dont bother.

you can do it, you need about half a dozen relays and some diodes, if you've a good idea about how it all works, you shoudl be able to do it fairly easily.

i wouldn' bother thinking about swaping the whole van to 24v just to save a few quid on a propex!

I don't know what the current draw is on a Propex ( no experience with them ) but I run a 24v webasto airtop 2000 on a maplins 140w. laptop inverter in my 12v mercedes 508d.
Everyone said it couldn't be done but it is working well within it's capabilities.(I bench tested for a month) If you know what your start up and running currents would be it may be suitable. The adapter was 1/2 price before xmas (£20 instaed of £39) so I gave it a try. The next (price wise) convertor I found came in at £65.
