Which is the best material for the water heater liner

1. Galvanized Liner

Galvanized Liner is the first generation of electric water heater liner, zinc protective layer only 0.06 mm, easy to rust, scale and short life, has been gradually withdrawn from the market, hot-dip Galvanized anti-rust resin steel liner replaced. Hot-dip galvanizing coating of anti-rust resin liner of zinc alloy protective layer of more than 0.7 mm, the surface can be covered with anti-rust resin, but the service life is not long.

2. Stainless steel inner liner

Stainless steel liner is usually used with titanium steel plate welding, light material, strong, high temperature resistance, corrosion resistance, not easy to rust, performance is very stable, suitable for a variety of water quality, a life span of more than 15 years. But when welding there will be weld, it is easy to be chloride ion corrosion, so in the use of water may occur. Therefore, the stainless steel liner generally use high-quality imported materials, so the price is higher.

3. Enamel liner

Also known as“Glass”, “Quartz enamel glaze”, “High glaze steel”, by the enamel layer and enamel steel plate two raw materials. The porcelain glaze on the surface of the inner liner is non-metallic material, which is non-rusting and anti-corrosion. With thick steel plate to do the gallbladder, pressure-resistant, service life of 5-10 years. Its price is moderate, heat preservation performance is good, suitable for ordinary families, is the current use of more extensive electric water heater tank, and most manufacturers promise to replace more than five years, so relatively practical.

4. Copper Liner

Copper liner heat conduction, corrosion resistance, pressure resistance, good ductility, antibacterial, both environmental protection, high stability, generally used in thermal electric water heater, common in developed areas in Europe and the United States.

5. Titanium and silicon tanks

The titanium-gold and crystalline-silicon insides are one of the more commonly used insides. The titanium-gold insides are mainly made of steel plates containing titanium, the silicon compound is baked at high temperature on the base of steel plate to make it adhere to the inner and outer wall of the silicon liner, both of which have good stability and strength.

Can you fix the leak in the tank of the water heater

Water heater liner leakage is not recommended repair, replace one. The leakage of the inner liner shows that the enamel has been damaged, repair will not take long to leak. Repair needs special equipment technology, in view of the stability of repair quality, usually big brands do not allow no on-line repair capacity of the maintenance station on the tank repair, so are replacement box.

How to clean the tank of water heater

In order to ensure the safe use of electric water heater and tank life, in the long-term non-use of the case can be through the safety valve of the tank water discharge, cleaning must be cut off before the power. When cleaning, close the intake valve, open the outlet valve, remove the drain cover (while checking the consumption of the magnesium rod so that it can be replaced in time) , drain the water in the tank, then open the intake valve and rinse repeatedly for several minutes, until the discharge of clean water, the magnesium bar will be re-installed, cover the drain cover can be.

Water heater rust solution

1. Use a plastic pipe connected to the small pipe at the relief valve outlet to draw water from the tank. Turn the wrench 90 degrees from the vertical position, when the relief valve is opened.

2, remove the hot water pipe at the metal hose joint, then you will see water from the relief valve, drain the tank of water, until the relief valve mouth basically no water flow, almost all the water in the tank has been released, and with the release of water, the tank most of the scale (flocculus) has been discharged.

3. Then connect the metal hose of the cold water pipe to the hot water outlet of the water heater, open the cold water corner valve, and let the cold water flow into the tank from the hot water pipe, at this point you can see the pressure relief valve outlet continues to flow out of the water mixed with scale. Repeat this step many times, after many times of Flushing, from the pressure relief valve outlet in the water flow is very clean, that the basic clean bladder.

4, finally the water heater to the original pipeline, when the water tank filled with water can be electrified. Prevent the water heater rusting method: regular water to clean the water heater nozzle, and keep dry.

Does the tank of the water heater still work if it's rusted?

Water heater liner general normal service life of 3-5 years, due to enamel rust caused by water, indicating that the tank began to rot, should not be too long service life. For your safe use, you can purchase a new machine, or let the after-sales staff to help you change the liner (usually manufacturers will not do so, because the liner and the body is the whole of the foaming and can not be taken apart) .
