Can anybody give me some advice about heat?My family adn i are looking to buy our first home (and we are pretty much clueless) and we have an 8 year old with cf.Although hes done relatively well from a lung standpoint i obviosly dont want to do anything to screw that up.But could anyone give us the pros and cons of gas vs. oil vs. radiator heat ? Is one better than another? Could any one of those potentially worsen lung function?
