And, of course, never leave a portable space heater unattended for fire safety reasons. Also, be careful not to overload your circuit breaker by heating with multiple portable space heaters. A space heater should never be used as a substitute for a permanently-installed heating system. A heat pump is a forced-air heating and cooling system. In the winter, the heat pump extracts heat from the cool outside air and transforms it into warm air from the furnace.
Heat pumps can deliver heating at less than half the cost of electric furnaces.
Since the temperature of the air from a heat pump is not as warm as the air supplied from an electric furnace, the heat pump needs a larger stream of air to deliver the same amount of heat as a furnace. Therefore, it is very important that all supply vents be kept open. Room vents should be kept open and furnace filters cleaned or replaced regularly. Your heat pump should also receive a tune-up once a year by a qualified service mechanic to keep it operating at its peak efficiency.
