Hey hows it going? I've had the same problem, keeping my coolside temp up. Today I just picked up a couple of the ceramic heaters and while they are pricey ($40 @ Petsmart) they work great! I keep my house 70-72 and was using the red infrared bulbs but they only keep the temp around 75* max and they dry out the air big time. I've got the ceramic heaters on a rheostat so I've got them set to full blast now and I'll start lowering the stats to obtain a cool side temp of about 80*. They're awesome get one!
