If my previous post still has not convinced you otherwise, the correct way
to connect one is to intercept the return water line from the engine to the
heat exchanger and connect in series the transfer coil in the colorifier at
that point.

I would like to install a calorifier connected to the boat engine. Could
somebody give me advise how to do it and how to avoid mistakes? My
engine is a Iveco aifo 8141 and I would like to connect a small
calorifier, preferably a flat one to fix it near the engine. Thank you!
