If it heats radiators then it can heat a calorifier.
There is no difference between the two devices other than where the heat goes.
A radiator is a water to air heat exchanger. A calorifier is a water to water heat exchanger.
Anything capable of doing one of those things is capable of doing the other.
if your calorifier does not have enough coils that's a different story so either a new calorifier with extra coil or a Morco.

Is your calorifier twin coil? I suspect not if its not already connected to the Alde. If not then that will need replacing as well if you dont go for an instant water heater. Alde still supply parts for their machines so everything is fixable and they can heat water as well as radiators. Modern heaters do mostly work with copper after all unless you buy a very expensive stainless steel calorifier then they are made of copper. Cost is creeping well above £3k by the sound of it

Uxbridge boat centre do (or at least did) single double or triple coil calorifiers. To order, horizontal or vertical.
You could replace the existing one.
Or maybe valve appropriately and use the Alde on the same coil as the engine.
Not sure how practical that would be as not tried it but probably doable.
I think you said you put a new Beta Marine unit in the boat and they usually have a separate calorifier takeoff which does not cause any problems if it is not being used.
Years ago I saw some stainless steel calorifiers in a scrap yard. Nice compact size but I was not engaged enough to work out they were gold dust.
ETA I do feel that getting the Alde working and routing it through the calorifier is the correct solution here.
It's a fairly expensive way to heat water but bottled gas is incredibly practical and if the unit is already installed then it seems a bit naff to rip it out.

Great idea I wonder what it is like in practice. Flue length?
From the description:
"It can be used both hot and cold water."
That's incredibly clever. I suppose the idea for the cold water is "do not light the fire". Who'd have thought that such useful functions would come so easily?

Maybe link it to a shower with a thermostatic tap?

That would be a wise precaution as using 75 degrees C water for showering is not for the faint hearted.
Damhikt.

I would guess the imagined usage is in connection with some sort of glamping scenario. It would take up a fair bit of space in a boat. And it's not what you might call pretty to look at.

Is glamping popular in Bulgaria?
I had the misfortune to be in close proximity to a glamping site this summer when passing through an upper Thames lock.
I really could have done with a machine gun to clear the catastrophically irritating middle class VW Touareg driving humanoids.

Are you not in favour of yurting?

Not at all. Too annoying.

I have long suspected you are a yurtisct.

My first priority was to heat water without engine running.
The Alde does not and never has heated the water.
I'd therefore prefer to replace with a modern system which does heat the water ... whether that's a new modern boiler, or the old Alde with a new calorifier I shall see and be advised.

Thinking outside the box you could get an immersion heater in your calorifier to use the extra power, over and above what is needed for the batteries, to heat the water OR get a full solar water heating system
