We purchased a brick house built in 1950. It is located on the shore of Lake Michigan in WI. My question: would the house be more comfortable in the winter if the basement was heated? Would that help maintain the temperature of the rest of the house? Does it make it more efficient to heat the basement? It is just a basement, but it does have a space heater.
It is always most efficient to heat the area that you want heated. Hot air does rise, that is why radiant heat is so popular. Since your home was made 50 years ago you still may have the old or no insulation. One of my houses is 70 years old and when the plaster walls were torn down, the exterior walls were void of insulation. I hope this answers your question.
