Bizlady, is this a heat pump or resistive heat?
Our house is set up very similar.
Do they have an off peak meter for the heat pump? If so, what was that meter showing for use in Dec? We tend to be home more in the winter, bake a lot more, and so use more electricity. Our heat pump use has never gone over about 1800 kwh in a month (heat pump and water heater).
Also, if it is a heat pump system, did you say you saw 'pipes'? Was this in the floor itself? Typically the systems I have seem use tubing, generally Pex I think. If you saw copper pipes, that may be something to investigate.
Also, they really should have laid down insulation under the tubing otherwise you would be heating the ground, as others have said. I would guess this would double the bill.
Any details you can provide may be helpful. Good luck!
