I recently placed my order for an Animal Plastics T10 with a handful of options. Due to their extended lead time right now, I have a while to place the order for my RHP from Bob at Pro-Products. I sent Bob an email about the T10 and my room setup / temperatures. I'm a little indecisive on what to go with based on his response (not his fault, mine)

So, I live in Northeast Ohio with a full 4 seasons. During the summer the A/C stays on the entire season and is set to 72. Occasionally I will drop it to 71. Winter time thermostat is set to 68 with an occasional bump up a degree or two. So the vast majority of the time the house is 68-72 degrees and Bob recommended a Pro Heat Model PH-3 75 watt 12" x 18" x 1" based on those specifics. OCCASIONALLY, the very short time or handful of days in spring and fall when windows can be open, I may forget to close them at night etc. and have a drop into the low 60s and at worst the high 50s for a short period of time. Also my thermostat can go into "ECO" mode in the winter if I am away from the house for a long time and drop to as low as 60 until I get home and go back up. Bob said for high 50's to low 60's he would recommend the Model PH-12 100 watt 12" x 24" x 1".

Looking for opinions on those with T10's and Pro Products panels and their environment & panel size. Not sure if the 100 watt is necessary based on the rarity, or if it is a good idea for the extra ability.
