When it gets below freezing the Sunbeam
space heater can only keep my room a little below 60 degrees.
That's when I use the DeLonghi
oil filled radiator heater.
We've got a more modern
version of this one made by Honeywell, but its got digital controls
which means it shuts off if the power flickers.
The oil filled sections do
hold heat for a while, but from my calculations that heat is gone
within 15 minutes.
Mark,
If you just get flickers when you want the heater on, you might want to buy a "night light" that will turn on when the power goes off. That way, if your heater goes off and the light wakes you up, if it was just a flicker you can turn it back on.
