Morning Baffle, nice project.
Just a couple of points, will you be adding an inhibitor and antifreeze to the indirect circuit ?
Hello Ducati - thanks for interest. Yes will add inhibitor/antifreeze once I 'm happy with the installation. Have had boiler up and running and it heats up fine and quick, and also lets the hob get most of the flames so we can still cook our toast on it I have a problem though with getting the thermosyphon to work through the water cylinder, although the radiator/s heat up fine and they are at the far extent of the thermosyphon circuit. Have discovered that coil in the cylinder was very squat, convoluted and narrow bore - i.e. not at all good for a gravity system, so am having coils in cylinder replaced with bigger bore deep coil. Hope to get cylinder back tomorrow, and fingers crossed this will do the trick.
Have been troubling folks on a canal boat forum with the thermosyphon issue - see http://www.canalworld.net/forums/index.php?showtopic=41586 Was planning to give a full update here once I had got it all up and running to my satisfaction (not forgetting to let Fintray know about tarring up etc!)
cheers
