Hi all. I purchased a house with a Tarm Solo Plus 60. This is my first season using it. I have been burning for about a month now and feel pretty comfortable with it. I have a question regarding chimney flue condensation. Here is my set up. The Solo Plus 60 is tied into my oil boiler and indirect fired hot water tank. I have a masonry chimney on an exterior wall with three flues. One for the oil boiler, one for the solo plus and one for a fireplace. There is also a draft inducer fan attached to the smoke pipe. I do not have any water storage. I have the boiler fan set to kick on when the temp drops below 180 F, per the instructions. When the boiler fan kicks on, the boiler temp rises to 190 F, this is also consistent with the instructions. When the wood is burning I get consistent flue temps of 550 to 600 F. This is perfect as I read in the instructions. Then when the boiler fan shuts down the flue temp drops to about 150 to 175 F. The draft inducer fan on the smoke pipe is always left on low (previous owner told me to do this). The Solo Plus is heating my house great. However, I have been noticing condensation coming from the chimney flue servicing the Solo Plus. I see it when I open the ash clean out door which is located below the smoke pipe to the Solo Plus. Over time, I have been noticing some water pooling on the floor of my chimney ash clean out. I cant tell if the condensation is also forming above the smoke pipe or if it just drips from the smoke pipe to the ash clean out. Is this normal? I am i doing anything wrong? Any advise would be greatly appreciated. Also, my cord wood is seasoned. I have tested with a moisture meter and its always between 15 and 22. Thanks in advance.
