Please tell me the functional differences including the pros and cons of a pressurized or non pressurized gasifier boiler?
Thanks for all of the feedback and links, lots of clarity now!Please tell me the functional differences including the pros and cons of a pressurized or non pressurized gasifier boiler?

Non pressured in most cases will require a heat exchanger between the boiler and the rest of the system .
Non pressured does not have the potential of a catastrophic steam explosion that a pressured boiler has .
No comparison between a domestic hot water heater , no real skill involved in its operation .Pressurized boilers will run in the 15-25 psi range. If a pressurized boiler is a time bomb waiting to explode should we consider a domestic hot water heater a potential weapon of mass destruction? Nah...
That is correct , the foam insulation prevented heat loss and possible freezing .So you've got an electric hot water heater for your expansion tank?
.
There is actually a schematic for a similar setup in my boiler manual, I think it's pretty common in Europe. Would also make it a lot easier to incorporate or add a solar drain back system too.
Without pressure don't you need a different pump (circulator) to get the water to the higher heat emitters? Say like on the second floor?
