°Hi all, It has been many years since I was in school, so my phisics is very rusty. I have a wood boiler that was made for me, that burns my access waist wood. The boiler gets my water to 155°, and maintains it. I have a "kiln" room that is fully insulated, no windows, insulated doors and a heat exchanger in the room. I need to get the internal temperature of the wood, Oak, to 175° to ensure it is dry and down to around 6% humiditey. I was told that a room can get warmer then the air being pumped in. Is this corect? If it is, any idea what temp the room can get. If this is not correct, any idea how to calculate the water temp required to get to 175°? Sorry if this is a stupid question, but I can't seem to find an answer.
