What's more economical and efficient all round, fitting a reverse cycle airconditioning unit or oil heaters?

What area is this in because it can really make a difference.

It's to heat up the entire house - 3 bedrooms, kitchen/family room area, dining and lounge.

The ducted gas heating broke down a few days ago and I've decided not to have it fixed since it's normally the biggest household bill - gets massively expensive
