Depends in what type of heating you have, the insulation in the building, and whether the windows, doors, outlets/wall switches are leaking cold air.

Our previous home was built in 1924, had a pressure steam boiler, and had zero insulation for the first winter we owned it. It could not keep up with the outside temperatures. We had to practically sit on a radiator to get warm. Many times, when it was really cold outside, we could see our breath inside.

That spring we had blown-in insulation installed. In the attic they laid insulation bats on top of the blown-in for a higher R value. The following winter, we had to turn the heat down from where we previously had it as it was way too hot in the house. The difference was absolutely astounding.

Our current home has spray foam insulation and a new propane forced hot air boiler. It has zero issues with keeping up with the outside temperatures.
