OK, my plan for my 6/1(s) is, as you probably know by now, to make a CHP setup. But before I go much further, I don't have any kind of cooling system for my Listers, which is not clever. So.... thinking cap on:
What if I buy an old indirect copper hot water cylinder (similar to this one:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=130290855979). I believe that has a heating coil, which I'd plumb into the Lister's water jacket, with a CH pump (e.g.:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=360135500735). Then bung some fittings onto the main tank, fill with water, and..... hopefully.... hot water!
Would that work, or would there be insufficient heatx area in the coil to sufficiently cool the water returning to the engine? I'd plan on putting several thermocouples in place to monitor temps; i.e. top & bottom of engine water jacket; inside tank.
Of course, plan B (if required) would be to use the main tank as the coolant source, and I could probably arrange it to thermosyphon in that case; and mabe use the coil to extract heat instead.
Please do bear in mind - this is just a bodge-it job, for now. I need some kind of water system to run the engine(s) for any length of time, there's no question of any of this being a permanant install - unless it works *really* well, of course!
