<br> recent years, household electric heater as a people must have one of the small household electrical appliances, more selling in the market. .When winter comes, electric heaters will become popular in many households purchase goods. .<BR> <BR> However, in many varieties, which actually buy it? .<BR> <BR> <BR> <BR> Type heater quartz heater: also known as infrared heater is a common product, the use of electric wire heating, inspired by the far infrared quartz heating tube. .Style with a long tube, short tube, vertical, horizontal and so on. .Advantage is that style lightweight, fast heating, heat evenly, and water proof, easy maintenance; drawback is due to radiation heating, heat transfer from the close, electric wire more easily deformed, quartz tube, such as careless, easily broken. .<BR> <BR> Far-infrared ceramic heater: heat through the heating filament to stimulate goblet glass-ceramics far infrared light waves to form issued by body heat. .Similar structure and the quartz tube. .PTC ceramic heater: used as a heating element PTC materials, the use of forced ventilation air conditioning principles to accelerate the flow of hot air to achieve the effect of indoor heating. .Advantage is warming faster, smaller, durable, no fire, safety. .Used in the power range, adjustable heat, more affordable, more applicable to the bedroom. .Convection heater <BR> <BR>: also known as heaters, fan heaters. .Is attached to the heater on a small fan, enhanced thermal diffusion, but also make the hot air temperature and body heat away, it is not suitable for use in the bathroom. .The heater has the advantage of better insulation, noise-free operation, more suitable for living, dining and bedroom. .<BR> <BR> Oil-filled electric heater: this is oil heat heater. .Work, heating oil around the tubes is heated, and then cycle along the heat pipe, heat through the wall surface and heat the indoor space. .The advantage is good sealing performance, insulation, all right; disadvantage is slow from the heat than the costs of electricity, relatively poor economy for the bedroom and bathroom. .<BR> <BR> Purchase method <BR> 1. .Note that the thermal efficiency of electric heating, the low level of marking technology products to high thermal efficiency, low power, heat, saving energy is preferred. .<BR> 2. .View of heat transfer. .Heater should be given the full transfer of heat to the required place, heated indoor air. .From this consideration, the better selection of enhanced convection. .<BR> 3. .See the safety of electric heater. .No open flame as far as possible and with automatic over-temperature power devices, and should shed no odor. .Flame sealed room in the winter consumption of oxygen, oxygen and pollution likely to cause the indoor environment, and therefore should not be optional. .<BR> 4. .According to room size selection. .General living room 10 square meters, should use 400 to 800W, 16 square meters living room, optional 800 to 1500W's. .<BR> 5. .Insulation under the living room conditions. .Poor conditions such as room insulation, heating the whole space will be a higher power, it should close the heater to buy, such as the effective distance of 1-3 meters in the far infrared quartz heater, infrared heater or halogen. .Such as insulation conditions are good, to be the overall space heated room, optional heating faster, even heat ceramic heater PTC, or Oil-filled radiator heater. .Into the autumn and winter, electric radiator again into the Langfang people's lives. .This winter indoor auxiliary heating tool because of its cheap so that more and more people willing to accept. .<BR> <BR> Reporter recently visited Langfang several appliance stores, in Hualong electrical appliances, electric heaters are placed in prominent locations around the full circumference advice from time to time, buy consumers. .Named Li told the reporter, "a room at home for the elderly and children need special care, electricity, heating just want to keep the indoor temperature is higher in some places more." In addition, the price is cheaper and flexibility has become a strong consumer purchase .the main reason. .<BR> <BR> According to sales staff, this year (2005) paid great attention to energy-saving electric heating, small size, many products have added support in the upper, dry winter clothing and footwear for consumers, but mainly in the 300 yuan price .to a thousand dollars or more or less, and there have been new products debut. .<BR> <BR> However, with colored electric heating, the public should pay attention to understand the buying or common sense, in order to choose a safe, affordable, energy efficient electric heaters have after-sale protection. .The industry covers the following aspects need attention. .<BR> <BR> <BR> Look for the brand to buy <BR> <BR> electric heating market so far, into the brand-name products is still limited, but some unknown products are emerging, in which the phenomenon exists in the mixed .If there are problems in the quality of products or OEM products. .<BR> <BR> Mostly in the form of these products on the copy brand-name products, but only in the panel and packaging a new look, confuse consumers. .Therefore, when consumers buy electric heaters, or should first do some research, look for brands or products at reasonable prices. .Do not just stare <BR> <BR> <BR> <BR> <BR> current price, the market price war has spread to the sale of electric heaters, consumers can benefit from it. .But at the same time, some manufacturers for the pursuit of market profits, production and manufacture of electric heating used inferior parts to reduce costs, and electric heating products for consumer ignorance, but possible to buy goods with low prices as a .the main criteria. .<BR> <BR> Each commodity has its inherent cost, if too low, is tantamount to suicide operations, then consumers should be cautious about its quality. .<BR> <BR> According to industry sources, the price is too low Youting it is possible to change the internal connection to ordinary wire; case with ordinary steel plate; not put heat protection device; internal parts shoddy; film and film .no strong connection between; some even reduce the number of pieces such as fever, so that the electric heating will be a security risk. .<BR> <BR> <BR> After-sales service after-sales service commitment is the key <BR> <BR> market competition has become one of the key household appliances, electric heating as well. .<BR> <BR> General, the well-known brand of after-sales service will be maintained for 3 years or so, and substandard products are often difficult to home repair and even manufacturers are not. .Consumers have to the other brand-name electric heating maintenance repair points. .<BR> <BR> In addition, consumers need to watch out when the electric radiator to see the connection with the film is solid, with or without thermal protection devices, heat number of pieces in the end how much film. .<BR> <BR> It is understood the market better internal wiring of the electric heating wire in aviation, oil heater is 0.6 mm in the normal case, the choice of double insurance Ex-Oil Heater.
