Many families are buying supplemental space heating units in an attempt to use heat only where it is needed and thus lower the total heating bill. lf you turn down your central heat thermostat and place such a unit in a room where the family spends most of their waking hours, heating bills may be reduced. Such savings appear to be significant, but each family first needs to carefully consider the safety risks and their energy savings potential as well as the lifestyle changes that might be necessary.
