We live in an older house, and have forced electric heaters in each room. The amount it would cost to plug in the space heaters runs about the same cost as heating with the forced air. We keep it pretty low though. We just put on more layers (sox, l/s shirts. ect). I spent every summer in Florida growing up and can uderstand the thin skin. But our bodies get used to the temp., and we just went to stay in a hotel a few weeks ago and were practicly sweating from them keeping it on normal heat. We even had to open a window in our room to get it to what are bodies are now used to.
