Ceramic heat emitter + lamp fixture question

I currently have my baby ball python in a 10gal terrarium with a UTH hooked up to a hydrofarm thermostat. The weather is getting chillier here in Toronto and I'm looking into ambient heating sources for the winter.
So far I have decided on purchasing a ceramic heat emitter along with a ceramic dome fixture and a lamp stand. I was wondering what the correct wattage would be for a 10gal tank. I am planning on adjusting the height of the lamp stand so that I can leave the CHE on 24/7 at the optimal temps, if necessary, I have a lamp dimmer just in case.

Have I chosen a good heating method for the winter or is there a better (although similarly priced) alternative?

Wattage will vary depending on how cold the room gets. I would get something in the 100 Watt range and use a lamp dimmer to keep it where it needs to be.

My room can get very cold during the wintertime, around 60-65F.

For my 10gal I used a 75w zoo med infrared light, I've recently switched to a zilla 75w night black heat bulb(gives off no light into the tank) both work about the same, mines raised off the top and in a ceramic wire lamp in the center of the tank, I would also get a rheostat/lamp dimmer as stated above.

a 100 Watt should be enough, a lamp dimmer will let you keep the temperatures right where you want them.
