Hi,
If it is a choice between oil filled and radiant I prefer radiant. However I use oil filled when sleeping.
I won't buy a heater that has computerized controls as if the power fails for a second or two that type does not restart.
I use (in no particular order):
oil filled
radiant
electric heated carpets
fan based resistance heaters
a heat strip in the air conditioner
heater bars
heating pads
dual window fan to blow warmed air into the cabinets (it replaces the return air grill on the propane furnace)
I am able to heat 100% electrically with a peak demand of about 6000 watts.
