I recently put some walnut and maple slabs in my utility room to dry out a bit, thinking I would have them kiln-dried in the spring. This room contains my gas boiler, which heats my house. Well the temperature in there is 100 degrees and humidity around 30%, so after 2 months all the lumber is down to 6% moisture content. The slabs are 1-2" thick and were cut from live trees this past fall. Anyone know enough about kiln-drying to tell me if there are drawbacks to this setup?
