1. Infrared radiant heater (commonly known as small sun) is very suitable for local heating. If you are easy to cool in the office, this kind of very economical heating method is very suitable for you. And that's hot when it's on. As long as it's facing the direction of the light, you can immediately feel the heat. When buying, try to choose products with dark light technology, and the larger relative effect of the reflector is better.


2. If you want to heat up the house quickly, you can consider the electric heating. It doesn't matter if you can't remember the appearance. The heaters in the figure below are all of this type. Because electric heating has forced air circulation, it can make room temperature rise very quickly. And the volume is relatively small.


▲ various types of electric heater

When buying, it is suggested to choose PTC ceramic, which has higher efficiency and lower temperature attenuation. Also pay attention to whether there is filter cotton at the air inlet. If not, it is better not to buy it, because machines without filter cotton are easy to let dust fluff into the machine, which is easy to cause machine failure and danger.


▲ European type fast heating furnace

3. There are also heaters of the above shape, but in fact, there are about three types according to the heating principle. It is recommended to buy convection heater, which is also called European fast heating furnace. It uses the natural convection way, when the work is very quiet, the bedroom and the living room which put in the home are very suitable.

When buying, try to choose the one that uses the dry burning electric heating pipe instead of the electric heating wire. It has high efficiency and long service life with metal heat dissipation parts. At the same time, we must pay attention to the use of three-phase plug when purchasing the metal shell products to ensure the use safety.

4. There are two other kinds, one is the electric heating oil heater that we are familiar with, and the other is a relatively new electric heating membrane heater.

Because of its good moisturizing effect, the electric oil heater is very suitable for use in the bedroom, and there is no noise when it is used. After shutdown, the heat divergence will last for a period of time. It's just that the weight is heavy and the heating is a little slow. These disadvantages need to be taken into account when purchasing.

The shape of electric membrane heater is changeable and light, so it is very convenient to move. However, at present, most of the electric membrane heaters are made in small factories in China. The product quality is uneven, the heating effect is not ideal, near hot and far cold, not recommended. If you want to try, try to choose domestic first-line brands.





How to choose the right power according to the indoor conditions?

Please refer to the following table according to the environment, expected heating rate and housing area:



It should be noted that the storey height in the above table is calculated according to 2.8m, and the higher part is increased according to the actual proportion. The actual life style, north-south orientation, adjacent situation of the house, region, heater brand and model will lead to differences in actual use effect, and the table content is only for reference.





1. The infrared radiation type heater should not be too close to the human body to avoid scalding because of its concentrated heat. Do not stare at the heater for a long time when using it. The infrared penetration may cause damage to the eyes.

2. Generally speaking, the heater has noise. People who are sensitive to noise should avoid this kind of noise. Do not block the air outlet when using, and regularly clean the filter cotton to prevent safety failure.

3. European type fast heating furnace also needs to be careful not to block the air inlet and outlet to avoid potential safety hazards.

4. Due to the heavy weight of the electric heater, attention shall be paid to the safety during the handling to avoid personal injury or oil leakage caused by external force damage.

5. The power of heater, European type fast heating furnace, electric heating oil heater and electric heating membrane heater are all high. Try to avoid using patch panel or other electrical appliances on the same socket.

6. Due to the low air humidity in winter in the north, the room will become drier when using the heater. It is recommended to use it together with the humidifier to ensure the health of human respiratory tract. And keep a good humidity, at the same temperature, the human body with high humidity can feel more warmth.

7. At present, most of the household sockets are 10a, and the actual maximum power can bear is 2200W. Appliances over 2200W usually need 16A plug. Please pay attention when purchasing. Do not use mobile socket for heaters over 1500W, and do not use other electrical appliances on the same socket. When purchasing heaters with metal shell, be sure to select the plug with ground wire. Once leakage occurs, the harm can also be minimized.
