Looking to build the above for my China made log stove ,we a re moving in to a narrow boat soon and would be handy to have. A back boiler for rads  was wondering if anyone has done similar ? I'm in 2 options
1 simple box pipe in pipe out
2 box with baffles to divert the water to make Shure it all gets heated ?
What are your opinions pls this will be a pumped system at to the location of stove n pipes ect

I fitted a similar design,
                            But ploppet it on top of the stove, then wrapped it in 2L2. The stove top was dimpled so i used a copper plate between the bottom of the boiler and the top of the stove. It only has to heat on rad 900mm x 500mm it has a small expansion pipe/vessel above the rad..The whole thing did not take long to install, it was an experimental venture but it is still there 2 years later. Grin
  It is basically the same design as yours made our of a 500mm x 150mm Box iron with a 4mm wall. It works really well on gravity alone.
   It captures quite a lot of heat from the straight up flue..

Nope, no baffle.
           Just in the low end and out the high end.  I did design  💓 shaped one that had half the water capacity and can semi circle the top exit flue.. it reacts quicker. the bigger one still heats the rad for 30 mins after the stove has gone out.

   This stove runs a separate c/h boiler.

One stove top boiler design , is shaped like the aforementioned heart and topped off with a stainless steel meal cover heavily insulated internally. It looked brilliant, except that one was tempted to try lift it off to see what was for dinner.

I have done this many times all very successfully. The biggest was an old oil boiler with the oil burner removed and a woodstove added instead. The other pictures are items available commercially but they also work very well. The advantage of the chimney heater is that it dosn't cool down the firechamber, also its only 80.
