Along with the unceasing popularization of water heater, the following disaster accident also continually increases. How should the consumers select and purchase a gratifying water heater? Actually, so long as pays attention to next several spots when selecting and purchasing, regarding the consumer is also not a difficult matter, the author today comes for everybody to introduce that selects and purchases electric boiler’s several small know-how safely:

First, brand service option

The consumers must examine electric boiler’s brand and post-sale service level, famous brand goods – the quality is good, the post-sale service is also good, moreover may enjoy to visit to install, moves to machine and so on free a series of services.

Second, capacity choice:

Capacity choice main consideration family population and hot water amount used and other factors. Generally the nominal volume is 30~40 liters electric boilers, suits 3~4 people to bathe continuously the use; 40~50 liters electric boilers suit 4~5 people to bathe continuously the use; 70~90 liters electric boilers suit 5~6 people to bathe continuously the use.

Third, i/b/e/s:

1. constant voltage constant temperature function: The electric boiler outlet pipe place increases sets at the advanced magnetization thermostat, not only has solved the water temperature now hot and now cold phenomenon, but may also avoid scalding the accident.

2. magnetization function: In magnetizing the thermostat forms the magnetic field, enhances the water the activeness, has the Bulgarian key function to the human body.

3. anticorrosion removing dirty stuff function: Because electric boiler usual work under 70~80 degrees water temperature conditions, the removing dirty stuff function appears especially important.

Fourth, is selecting and purchasing, but also needs to consider the following matters needing attention:

1. viewing test: The outside surface baking varnish should even, luster be luminous, not falls off and does not have the dent or scratches, the extrusion trace seriously and so on; Each kind of switch and knob handsome appearance, the processing is fine; Calibrated dial and other handwriting should be clear.

2. takes strict precautions against the counterfeit and shoddy products: The counterfeit and shoddy products often use the adulteration trademark and packing or will assemble the brand to pretend to be the import original installation commodity. This kind of commodity common outward appearance is rough, after the circular telegram, the elevation of temperature is slow, cannot achieve the standard.

3. the appendix must be complete.

4. inspection of the attaching plug: The wiring must the reliable and complete not bad contact phenomenon.

5. circular telegram experiment and constant temperature servicing check: Looked whether the first indicating lamp lightens, the water leakage power failure instructed whether reliably. When constant temperature inspection, when temperature hypothesis certain value, achieves the setting value, the electric boiler can the automatic power failure or the transformation power. If meets the above requirements, explained that the electric boiler constant temperature performance is good, otherwise is not normal.
