In winter heating equipment selection, heaters and air conditioners are often compared. There are significant differences between the two in heating principles and applicable scenarios, and they need to be scientifically selected according to needs.
The heater generates heat through electric heating wires or PTC ceramic heating elements, and the fan blows the hot air directly out. It belongs to "local convection heating" and heats up quickly (you can feel the warmth after turning on the machine for 3-5 minutes), but the heat coverage is limited; the air conditioner relies on the compressor to circulate Freon and release heat through the indoor unit evaporator. It belongs to "overall environment heating" and takes 10-15 minutes to increase the room temperature, but it can make the space temperature more uniform.
The heater is suitable for short-term heating in small spaces (10-20㎡), such as preheating the bedroom before going to bed and heating the office desk. Its small and portable features (some models are only 2-3kg) are also convenient for mobile use; air conditioners are more suitable for long-term heating in large spaces (more than 20㎡), such as living rooms and whole-house heating. Especially when combined with frequency conversion technology, it can maintain a stable temperature and is suitable for all-day operation.
In terms of power, heaters are usually 1000-2000W, and continuous use consumes a lot of energy (about 1-2 kWh per hour), and hot air can easily cause air dryness; although the air conditioner has a high heating power (1500-3000W), the frequency conversion model reduces power after reaching the set temperature, and has better energy consumption. Some air conditioners with humidification function can also alleviate the dryness problem.
After a power outage, a heater can be used with a battery, while an air conditioner relies on a stable power supply; bathroom heating requires a dedicated heater with a waterproof rating of IPX4 or above, and the air conditioner should be avoided in areas with high humidity to prevent short circuits.
After understanding the difference between the two, you can choose according to the size of the space, usage time and functional requirements: choose a heater for quick heating in a small area, and choose air conditioning for constant temperature heating in the whole house. Reasonable combination can improve winter heating efficiency and comfort.
