Would the filling of a tank volume with low density foam, sponge type,
help to reduce thermal losses ?

It would help a little - but probably not significantly. Surrounding
the tank with insulation would probably be the most cost-effective
loss reducer.

 What do you mean? Prohibit circulation? Then how do you want to get the heat
in the tank?

 Well the heat exchanger needs circulation to get the heat inside the tank...
heat does not diffuse very well without circulation (that's why insulation
works - very small gas bubbles with few - the less the better -
circulation).

Much easier and cheaper anyway if you put the tank in external insulation -
the more the better, as Morris also said.
