Could and should I use a CHE to get the ambient temperature up in the winter?

Our house isn't the newest and sometimes gets relatively chilly in the winter.
Should I use a ceramic heat emitter to get the temp up?

If yes, how high of a wattage would be enough? how much would a ~50w "bulb" heat? I'll be having a UTH too as the main heat source.

I've looked up some CHE "bulbs", and some said to only use it with a cage-like cover. could I also use a regular heating lamp dome?

Would I need a thermostat? Even on lower wattages that don't heat too hot?

I'll be getting my first snake soon, and still have many questions I need answered before i get it.
