Just a idea for some of you with forced hot air furnaces. I changed my thermostat last year to a Lux Products CAG1500 Clean Cycle Clean Air Programmable Thermostat. You can program it to turn on the circulation blower motor on the furnace multiple times an hour to promote air circulation thru the house, and it also helps filter the air in the house since it it running thru the furnace filter. I found it help heat the house more evenly when using the pellet stove.
