Which uses more energy - a zoned reverse cycle aircon or a column heater?
Hi can someone help me please? Now that the weather is turning cold, I want to know which uses the most energy in a 4 bedroom, (insulated roof) house - a zoned, reverse cycle air-conditioner or a column heater in a single room. Thanks
