Sorry I cannot offer any help of this subject, but I am curious as to what temperature the engine cooling water must reach to be of any use in heating a calorifier.
My Bukh DMV10 engine runs at 60 deg C which is within the official engine spec and is the temperature rating stamped on the thermostat housing and is consistent with the reading on the temperature gauge. I tested the thermostat in a saucepan of water to confirm it opens and closes correctly. The system is open vented so is not expected to reach high temperatures under normal working conditions.
If a calorifier is to be fitted then I assume you would need a much hotter engine with probably a pressurised cooling system like on a vehicle. I do not intend to try fitting one on my boat but cannot see how it would ever work if I did.

Our BMC 1.5 seems to run at a nice solid 80, rising a bit when you really push upstream against the flow on the eastern arm on the Severn at Gloucester.
Once the thermostat opens it works a treat - but I suspect 60 would be a bit too cool
