IMO, a forced air heater is better than radiant because forced air makes the whole room feel warm. Radiant will only warm the part of you that is facing the heater.
We use a forced air heater by Vornado
. Their heaters are a little pricey, but they are very good at distributing the heat, and they are very quiet.
We rarely use our furnace. Even though the campground where we spend our winters in central Florida has metered electric, we still use the electric heater. The heater is MUCH quieter than our furnace, and we don't have to worry about running out of LP gas. With an increase in electric rates at that campground last year, heating with electric was slightly more expensive than with LP, but we still used our electric heater because of convenience and because it is so quiet.
