I have never lived in a house that uses propane so I have no experience other than using my grill to cook steaks. Does propane heat a house as well as natural gas. Are there any notable differences? If I have to replace this unit at some point gas is now available in the area, so I will have the option. The local utility Co. will charge me 1K to bring it into my house I would spend that if it's worth it in the long run.
