Heaters are more energy efficient.

When the household air conditioner is heating up, the refrigerant of the outdoor unit is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (at this time, the condenser), and the condensate is liquefied and exothermic, which becomes a liquid, and at the same time the indoor air is heated, so as to achieve the ultimate goal of increasing the internal temperature. The heater is a combination of a fan, an electric motor, and a radiator. It is suitable for various types of workshops where air recirculation is allowed and can be used for heating circulating air when the air does not contain dusty and flammable gases.

The heater is mainly composed of an air heater and a fan, the air heater dissipates the heat, and then the fan is sent so that the indoor air temperature can be adjusted. The energy efficiency ratio of the heater is less than half that of the fixed speed air conditioner of the same power and less than one-third of the inverter air conditioner of the same power.
 

1. Report

Energy efficiency of heater and air conditioner (1) Heater energy efficiency ratio: 1:1, power consumption of 1000 watts, generation of 1000 watts of heat.

(2) The energy efficiency ratio of the air conditioner: 1:3, consuming 1000 watts of electricity and generating 3000 watts of heat.

(3) For the same amount of heat, the energy consumption of the heater is three times higher than that of the air conditioner.

2. The energy consumption of different rooms is different

1. If the room is less than or equal to 20 square meters, the heater is more cost-saving

Energy (1) Heater: Suitable for heaters with an output of 1800 watts.

(2) Air conditioner: Suitable for 2hp air conditioner, heating power 1800 watts + auxiliary electric heating power 1500 watts = 3300 watts.

(3) For a room of 20 square meters, the use of a 1800W heater is right, and the energy consumption of the air conditioner is much higher than that of the heater.

2. The air conditioner in the room of more than 20 square meters is more cost-saving.

Energy (1) The energy efficiency ratio of the air conditioner is high, and the power consumption of 2 horse air conditioners is 3300 watts, which can produce 1800*3 + 1500 = 6900 watts of heat, which can increase the temperature of the whole room to 20 degrees.

(2) The heater has low energy efficiency and is suitable for local heating, which has little effect on raising the temperature of the whole room. Even if you use a heater or heater that consumes 3,300 watts, it can only produce 3,300 watts of heat, which is less than half the same power as the air conditioner.

(30) If the area is more than 20 square meters, use an air conditioner for heating, and the air conditioner will produce 3 times more heat than a fan with the same amount of electricity.

3. Heaters and air conditioners are suitable for different households

(1) The air conditioner can be turned on and off regularly, and the temperature rises rapidly, which is more suitable for households with non-fixed heating time but a certain period of time and good space tightness.

(2) The heater is suitable for small apartments or rooms, occupies a small space, is easy to move and simple to install. If the power supply to the appliance is unstable or your electricity bill is high, do not use a heater.
