I'm pretty sure that even triple glazed windows will have a very low R value compared to even a 2x4 wall insulated with fiberglass so they are good sometimes bad others.

Traditional fireplaces (open fire, straight up chimney) are usually a net heat loss but better ones can be great. My airtight insert does a wonderful job of heating the house as would a woodstove. If it had an outside air supply it would be even better but it's very very hard to add one since it wasn't planned for in the first place.
