First,it decided whether the factory has a certain scale and long producing history which means that the performance of their products are constantly improving,whether they've passed all kinds of certification of quality and management,whether they have large scale automatic integrative producing system and whether they have strict inspection means which is also a quite important judging standard.
Secondly,to choose suitable varieties.Generally,electric water heaters include water-stock mode and quickheat mode.The latter one can heat up quickly,however its power is very high, so general family's ammeter can hardly afford so high a power.The waterstock mode has the features of even waterout temperture,moderate heating up power,high security factor and so on.
Thirdly, it decided by the product performance.Seeing whether the products have world advances technology and measure in high pressure resistant, hot resistant, anti-corrosion, creepageproof and heat preservation, whether they've passed multinomial secure and quality certification. Because cerdible quality doesn't depend on propaganda or lip-service, but testified by the fact of the long producing history and the excellent record of non-accidents.
Fourthly,it decided by material selection. In order to save costs and increase profits,some factories don't pay attention to proper choice of materials.They adopt ardinary plastic for product crusts and then rips occur(For the plastic facture is simple and is easy to bring rips)and the insulated material is also locally filled,not totally filled so that the price is favorable,but the quality is also at a discount.
Fordeary has a long history producing electric water heaters and has world advanced product line.They introduced enamel boilers which is durable,with multiprotection,secure and credible,with over thick heat preservation,high efficiency and energy conservation,dainty choice of material,elegant and pretty.
