A few weeks ago we installed Gas heating and a Gas stove. Propane Gas prices have fallen significantly due to fracking up north, Gas now represents a significant savings in our area over fuel oil per BTU. Our old oil burner furnace needed costly maintenance, and our old electric range had developed burner problems, so we replaced both.
A 96% efficient unit, the new furnace looks like a computer inside; a giant circuit board dominates the interior. Much smaller as well, sidewalls were fabricated larger than the actual unit so the old ductwork matches up. Concerned such a small furnace wouldn't have the gusto to push through our old 4" ductwork, it actually works better than the old furnace did, with more airflow and more consistent heating throughout the house.
Best part of the install is the Gas stove; it cooks quickly with even heat and much more control than the old electric.
