Would NOT purchase again !!!
Warrenty is lifetime, Ha ! There is a plate between the two Heat Exchangers and is NOT considered part of the Heat Exchanger is what I'm told by the dealer. Mine is leaking from one camber to the other due to a pine hole.To me the cost to repair, I might as well but a new unit and it won't be a Bosch.
