Anyway, get an electric blanket and shut the heat off. Or like I do set it at around 62 - 65 degrees. I have one of those oil filled heaters and they work great. Using electric heat it takes the same amount of BTU's to heat a room if your using a radiator or forced air.
Just heating the bedroom with electric heat is less costly that heating the whole house by any means.

AS i stated before, there is a situation that triggers the switch to aux heat, so long as the OUTSIDE ambient temp is warm enough to allow efficient heatpump operation. Lets say you want a significant increase in temp, so you bump the thermostat setting from 64 to 68. The aux heat should kick in, as it will warm up the house much faster than the heatpump can. Once the new INSIDE temp setting has been reached, the heatpump should take over to maintain the new setting, at least until the OUTSIDE abient temp drops near freezing. Then a separate circuit switches the system back over to aux heat, usually a resistanc heater, because the air to air heatpump doesn't work effectively in freezing temps. As long as outside temps are at or below freezing, the aux heat should stay on. Otherwise the heatpump would be running constantly and barely heat the house. That's why heatpumps haven't been popular in colder climates.
