I would say keep things as simple as possible the less things to break the better.
A Dickenson diesel stove with the coil for Hydronic use and like straycat says plumb the return from the engine to the stove tank. You can run a red dot heater installed anywhere you like. and as many as you like. It is just a fan motor.
There is a learning curve to cooking on a diesel stove but once you get it down it really works great.
I live in Alaska and never have days above 75 deg or so. I run it all winter long down to-30 deg.
My Dickenson stays on all the time I am on the boat. Keeps the whole boat warm.
Once lit you never have to mess with it till you turn it off. 24/7/365
With the Hydronic you will need a small circulating pump. Less chance of a failure with that than an Espar Wallas or Wabesto All require maintenance
