Thanks very much for your replies. Double-paned windows were installed throughout the two-story house two years ago. Insulated vinyl siding also. This has just been a pretty rough winter, so far.
The electrical service is probably less than thirty years old. My step-dad was a master electrician and, years ago on one of his visits here from Florida, did a thorough check of the electrical system (not for me, mind you, he had grand-kids to protect! lol). His verdict? "The guys who put that system in certainly knew what they were doing." Coming from him, that was high praise.
There are actually two circuit breakers controlling the living room. Two wall outlets (one of which has the do-dads for one terrarium plugged into it) are on a breaker that didn't trip. On the circuit breaker that was tripping, there are also two wall outlets and the ceiling lamp on it (the lamp was off at the time). The TV was on one plug in this breaker and, across the room, one terrarium with all its electronic "do-dads" was on the other plug. (The "do-dads" for both terrariums are a UTH, two CHEs, the thermostat, and two in-line dimmers -- everything all plugged into an A/C strip. The heater for both terrariums is plugged into the other space on the wall outlet near it.
While everything seems to be working well (with the heaters on the low setting), it appears that hiring an electrician to put heavier wire in the living room and leading to the circuit box is in my near future. (sigh)
