20. My back-of-the-envelope calculation says it *could* be a gas explosion...

... but conditions would have to be exactly right.

A large volume of the house would have to be filled with an explosive gas-air mixture. How that could happen I can't guess. There would have to be quite a bit wrong with that furnace, starting with a plugged or disconnected flue and some sort of failure that allowed the gas to keep flowing and the air circulating even though the furnace wasn't lit. Any modern furnace has multiple redundant safety features to prevent this.

If you filled the entire house with an explosive gas-air mixture maybe you'd get an explosion equivalent to 50-250 sticks of dynamite.

From wikipedia I got a stick of dynamite = 1 MegaJoule of energy
