OP, what temperature exactly do you keep your house at in the summer and winter? Many are assuming you keep it at 50 degrees.

Now, if your house isn't actually 50 degrees (because as others have said, I don't think any heat source would overcome that), you can definitely use a heat lamp to raise ambient temperatures. Go for a blue light or infrared light because you will probably need to leave them on all the time if the area is cooler. You can use in conjunction with a UTH. Thermostat is required for UTH.

Do heat lamps and CHEs dry out enclosures? Yes. But this is also manageable with the right substrate, misting, humid hides, a room humidifier, etc.

The safest bet would be to try a practice setup of your enclosure for at least a week or two with no animal so you can determine whether your heating elements are sufficient or within the realm of being sufficient with adjustments.

And having cats and dogs is not a deal breaker either as long as you follow common sense safety precautions. Whatever you decide, best of luck!
