So ymmv but thats been my experience. Now back to watching youtube videos about how to install hot air ducts to deliver the hot air from the miners in the basement up to the rest of the house. It's getting COLD in northeastern PA!

Does S4 heat up your house as good as S1s and S3s? If so, it should be good for the winter months. Summer months will be another story with AC and fans blasting.
