This site is for both the United Kingdom and the United States as well as for any person from any country who would like to participate.

As far as answering your question according to what is best where you live, then hopefully people will come along who know about what is best where you live.

My thought right now is, that generally, homes with carpeted floors will retain the heat better than those with no carpets. Just my take on it right now. Perhaps someone will come along with a better explanation though. The floors in my home are almost all of wood. My home does not tend to be warm in the Winter.

Carpet does in fact offer somesort of insulating factor. Hardwoods tend to be slightly warmer than vinyls or laminates. Ceramic tile seems to me just transfers the temp of the concrete straight to your feet. Im not sure about marble but I imagine its about the same. I have installed alot of carpet and vinyl over the years some hardwood and tile as well so this is based on the differences I have noticed not on any factual data.
