Scholar Gypsy Posted September 21, 2013 Report Share Posted September 21, 2013 (edited) I have been reading with interest recent threads on central heating systems run from the engine, all very helpful (in particular this and this). I would be grateful for advice on sourcing small single panel radiators: the smallest I can find on general plumbing websites are 400mm long x 300mm high x about 60 deep. Has anyone found any smaller than this? (apart from very expensive designer rads, which I don't want). Many thanks Simon [background: my winter project is to install a couple of radiators in the back part of the boat - the front half is amply heated by the stove. We have an unused heat exchanger on our Mitsubishi engine - between thermostat and skin tank. The calorifier is connected to the bypass circuit ie before the thermostat. So all I need to do is replace the blank end caps on the heat exchanger with normal ones, install a small pump, header tank, a mix of flexible, copper and plastic pipes (15 or 22mm - not quite sure which yet), and a few valves to fiddle with. We had this on the previous engine, with a ridiculously expensive pump made by BOLIN - still in production - but lost it when the back half of the boat was replaced. Some of the locations on the boat that I am thinking of using are quite constricted] Edited September 21, 2013 by Scholar Gypsy Link to comment Share on other sites More sharing options...

Guest Posted September 21, 2013 Report Share Posted September 21, 2013 I seem to recall that 400 mm x 300 mm were the samllest when I looked, but may well be wrong. Link to comment Share on other sites More sharing options...
smileypete Posted September 21, 2013 Report Share Posted September 21, 2013 Another compact option could be to use a car heater matrix, have a look at this thread: http://www.canalworld.net/forums/index.php?showtopic=59800 cheers, Pete. ~smpt~ Link to comment Share on other sites More sharing options...
