1. Distinguish between types and purchase as needed. Unlike electric heaters, which rely on radiation to dissipate heat, heaters are characterized by forced convection heating, which can rapidly increase the room temperature. When you choose a heater, you should first determine the bedroom type, bathroom type or dual-use bathroom according to the purpose of the family. Type a must have good waterproof function. Secondly, in order to obtain satisfactory heating effect, pay attention to whether the heating area of the heater is consistent with the use area.

2. Look at the heating material. First of all, ordinary electric heater and PTC heater should be distinguished. The cost of electric heater is relatively low. The electric heating wire is generally made of ferrochrome wire, which is usually a small heater. The price is relatively low, and the power will be smaller. The power is set at 1000W~1800W, the heating area is small, and the price of electric heater is between 100~200 yuan. PTC heater is heated by PTC ceramic plate, which has no light and oxygen, and high safety performance. It is a relatively high-end heater material at present. The power setting is generally from 1800 W to 2000 W, the heating area can generally reach 21 ㎡ to 30 ㎡, and the product price generally ranges from 150 yuan to 700 yuan.

3. Various styles, safety first. At present, there are desktop, vertical and wall-mounted heaters on the market. Desktop heaters are small and delicate, vertical heaters have smooth lines, and wall-mounted heaters save space. The heater is generally beautiful and generous, with red, dark gray, blue and other popular colors. The shell makes the heater quite fashionable. But when purchasing heaters, we should also put safety first. Whether the machine has a protective device for overheating and overcurrent, and whether it has the function of dumping and power-off. Especially the bathroom heater must be waterproof and splash-proof, so carefully check whether there is a waterproof sign on the machine.
