I am in FL. and every year there are a few days when we need a small
electric heater to help warm up the great room - no point in heating
up the rest of the house by running the furnace. Last year, I bought a
Pelonis oil filled radiator and brought it home and tried it.... we put
the built in thermostat on high and turned it on. The room itself was
not cold when I did this...the heat came on but it put out very small
amount of heat. It would not have helped on a real cold day so I
returned it to the store.

Today I went looking and was only able to find two brands. One was
Pelonis the other Honeywell and they appeared to be twins in everything
but name.

Does anyone have experience with these? Would the heater have put out
more heat if the room had been cold? Or should I be looking for a
different kind of heater? Thanks for any help.
