Reply #10: All electric heaters are technically 100% efficient. [View All]

The only difference is how good or bad they are about circulating air. Just use the same heaters and get the air moving. Generally you want a good but slow churn in the room, and especially moving air up in the ceiling area down to the floor. A nice ceiling fan if you have a sturdy fixture, failing that, an aimable floor-mount.

Not that electric heat is recommended -- waste of good electricity. But sometimes us renters have litte choice.
