Heating system is safer than a fireplace/space heaters

I live in a part of the country that gets very extreme winter weather for most of the year. It’s very cold and miserable and if you don’t have a way to properly warm up your home, you might not survive. So I’ve been trying to think of ways to efficiently warm my home without having to spend a ton of money. I know the most cost effective way to heat your home is to use space heaters and a fireplace, but they are not very safe. I have a few young children and I want to make sure that my home is safe and not a fire hazard. I’m tempted to go out and buy a few space heaters, one for the bedrooms and living room, but I can’t have a space heater in my child’s bedroom without being scared they’re going to knock it over and cause a fire. So I decided to call a local HVAC company and get their opinion on the best way to efficiently keep my home in the winter months. I hope they can give me some good advice because I don’t want to spend a ton of money to keep my home, I am a single mother and I can’t afford a fancy heating system like the people in the houses around me. I struggle with money and want to make sure that I am making the best financial decisions. I am torn because all I want to do is get a space heater but now it’s not the best option
