1. Pay attention to the thermal efficiency of the electric heater, its level indicates the technical level of the product, and the one with high thermal efficiency, low power, large calorific value and energy saving is preferred.
2. Look at the way of heat transfer. The heat emitted by the electric heater should be fully transferred to the required place to heat the indoor air. From this point of view, it is better to choose the enhanced convection method.
3. Look at the safety of electric heaters. There should be no open flames as much as possible, with an over-temperature automatic power-off device, and no peculiar smell should be emitted. The open flame consumes oxygen in the sealed room in winter, which is easy to cause indoor hypoxia and pollute the environment, so it is not suitable for use.
4. Choose according to the living area. Generally, a room of about 10 square meters should choose 400 to 800W, and a room of about 16 square meters should choose 800 to 1500W.
5, according to the room insulation conditions. If the thermal insulation condition of the room is poor, the heating of the whole space will consume more electricity, so it is advisable to buy a heater close to the body, such as a quartz far-infrared heater with an effective distance of 1-3 meters, or a halogen far-infrared heater. If the heat preservation conditions are good and the overall space of the room needs to be heated, PTC ceramic electric heaters with fast heating and even heat generation, or electric oil heaters can be purchased.
The above is about heaters for household use. When purchasing heaters for home use, you should pay attention to the heating efficiency, and also observe whether the heat transfer method is good or not, and whether the safety is high. Only by paying more attention to these small details can you ensure that you buy one that suits you. Home heater.
