If we get an Eden Pure can we sell our house with it?

We have an old fashioned gas space heater for our living and dining rooms. We use cheap electrical space heaters for our bedrooms.

If we get a big Eden Pure and small ones for the bedrooms, then remove our old gas space heater from our home, will the Eden Pure's be acceptable as a heat source when we sell our house?

I want to be certain that we will not be hurt in the long run if we remove the old fashioned gas heater.

Thanks!
