One more thing as a side note. This is just a discussion about heating preferences. Throwing out condecending words or phrases such as "bad choice", "bad option", or "naive" is really uncalled for. Something is only bad if its going to be harmful to the inhabitants...everything else is our opinion on what would be the best approach to handle the issue at hand. On other forums there are bloody discussions on stupid things simply because people act like their's is the only way and everyone else is just doing it all wrong. But when it really comes down to it ....its just our opinion....and nothing more.
