Because in the winter the cellar is warmer than the house,
- it gets heat from the earth.

Is this a good idea or daft?

You will simply make the cellar colder and then heat will
transfer from the house.

I don't think it is a good idea. Outside, ideally on a
South or South West aspect sheltered from North/Easterly
winds would be ideal.

If you had any land then installing at one end of a closed
polytunnel might work too, but if you had any decent land
then a ground source heat pump might be a better bet,
depending on your location and soil type. Nice sticky
clay is best (AFAIK).
