Might one expect extra maintenance or issues for a wood stove with a thermal fin heat exchanger such as the Ironstrike Grandview 230? Is it a potential of needing regularly replacement? When I search "heat exchangers" in general the term is used in other forums for appliances and talk of cleaning rods, etc., Just learned of this stove today - 2.3 cu foot firebox is nice for a small-medium stove.
