DHW and hydronic with wood stove

Hi guys, I'm about to build a wood stove that will produce DHW and heat the house with the hydronic system with radiators. I would appreciate any advice on the best hydraulic system to be adopted.
The sketch below includes a boiler being directly heated from the stove connected to an open vessel and to the radiators. Inside the boiler there is also a coil for DHW that for simplicity I have not plugged in the drawing.

This other scheme instead presents a smaller boiler connected to an accumulation tank in turn connected with the radiators. Between the heater and storage tank a natural movement should be established.

What do you think about it? Any suggestions?

It seems that images don't work, anyway these are the links:

Thank you Burra. I think the first example is simpler and it doesn't involve natural circulation but the space reserved for the boiler inside the stove can be limited.

Instead in the second example you can place a little boiler inside the stove and maybe use a very big water storage to collect hot water. Do you think this is correct? Do you know other methods?
