I'm considering options for an insert that could also be tied into our baseboard heat system and hot water. Anyone have any opinions or experience with this product? http://www.hydro-to-heat-convertor.com/. It looks like the best of all worlds? Advantages and disadvantages? I would like to do some major chimney/firebox reconstruction to accommodate something like this, but if the benefits are as great as they sound it would be worth it.
