Many copper water heaters on the market are often treated with copper plating on the surface, but their internal material is not copper. Therefore, when purchasing, it is important to pay more attention and carefully observe whether the cross-sectional interface of the water heater is made of copper material. Therefore, when purchasing, you can use a small knife to scrape the interface of the water heater to see how its internal material is.

1. Selection of water heater valve core:

When choosing a copper water heater, do not forget to select its valve core. The valve core of a high-quality water heater is generally made of ceramic material, which has good sealing performance and wear resistance. Therefore, when choosing a water heater, it is necessary to ensure the material of its valve core. If it is difficult to choose, it is recommended to ask the seller to provide relevant evidence and include the purchase terms in the contract for future use.

2. Touch more with your hands:

In order to ensure that the selected water heater is made of all copper material, it is recommended to touch the surface of the heater as much as possible during the selection process. After electroplating the copper material, the product feels heavy and has a high surface resistance. If the surface feels smooth, it indicates that it is not made of copper material and it is not recommended to purchase.

3. Tap to listen for sound:

When selecting a copper water heater, in order to determine whether its material is copper, you can tap its surface with your hand and listen to the sound produced by the water heater. If the sound is crisp when tapping, it is stainless steel. If the sound is dull when tapping, it indicates that it is copper material.

4. Bubble maker selection:

When selecting a copper water boiler, the quality of its bubbler should also be considered. Generally, high-quality bubblers are made of ABS engineering plastic material, which has the sound of filtering flowing water, causing more bubbles to be generated in the water flow. Water splashes will not splash, and it can also achieve energy-saving effects. If it does not have a bubbler or its material is not good, it is recommended not to purchase it.

5. Check accessories:

When choosing a fully copper water heater, it is also necessary to check the accessories. Good accessories are generally made of copper material, while accessories made of other materials, although the surface has been electroplated, will become pale and yellow in color during use, and will also turn black, affecting use and aesthetics.
