The heated & enclosed underbellies that are common nowadays can be a problem. Hot air blows from the furnace into the underbelly cavity and straight outdoors from all the cracks and openings.

If you aren't using the tanks and water lines in sub-freezing temps, you won't need the underbelly heated.
