I have managed to plum 1/2" copper pipe into my existing baseboard radiator system using a circulator pump @ 5.3 gallons per minute . This is attached to a pot of water { 20 gal. - I think } that sits on top of my wood stove . We boil the water and circulate through the coil . Temperature output ranges 130 - 140 degrees F ; depending on cycling interval . I also have a rocket stove set-up that provides the same function . That is able to reach 160 degree output ; but , as we know - that requires constant loading . Just like a steam engine - rolling down the tracks .
Both methods are open top pots where no pressure builds ....
Looking for a way to improve temperature output using my wood stove . That requires substantially less loading times ....
any ideas - please
thanks , c.j.
