What buyers said once the tank was on site — every review left on our Alibaba store, in their own words.
The enamel hot water tank from LVJIA is built on the Enameled panel system at our own plant in Dezhou, Shandong. A hot water cylinder fails from the inside, and it fails because of two things: scale and the corrosion that follows it.
An enamel hot water tank is a bolted tank whose steel panels are fired with a glass glaze at high temperature, so the surface meeting the water is chemically glass rather than metal. It does not rust, it takes no coating and it adds no taste, and the glaze is fused into the steel rather than painted onto it. Panels come in 3 × 1 m; 2 × 1 m; 1.5 × 1 m; 1 × 1 m; 1 × 0.5 m; 0.5 × 0.5 m, and the tank is rated for water between 4 and 100 °C.
Heating hard water precipitates calcium onto the hottest surface, and on bare steel that scale keys into the rough oxide and traps water underneath, where corrosion then starts. A fired glass surface is smooth and non-porous, so scale has far less to grip and tends to flake off as the cylinder cycles rather than bonding to the wall. A sacrificial magnesium anode protects the small areas around fittings, and replacing it periodically is effectively the whole maintenance schedule.
The panel is pressed from 2 to 4.5 mm steel depending on where it sits in the wall, then enamelled on both faces so the outside is protected as well as the inside. Assembled, the wall section measures 12 mm. Panels bolt together on a sealed joint, and because the glaze is inert the same tank handles potable water, fire reserve and mildly aggressive process water without a change of specification. LVJIA runs the enamel line at Dezhou under ISO 9001.

Storage temperature is rated to 100 °C. Domestic cylinders are commonly 100 to 500 litres, with the anode positioned for access from the inspection port.
| Tank height | Panel thickness | Typical use |
|---|---|---|
| Up to 1.5 m | 2 mm | Shallow or roof tank |
| 2.0 m | 3 mm | Standard sectional tank |
| 3.0 m | 4 mm | Deep tank, high static head |
| 4.0 m and above | 4.5 mm | Maximum height, braced |
Every enamel hot water tank is filled and held at full head before it leaves the factory, and no joint is allowed to weep. The plant is certified to ISO 9001 and the inspection certificate ships with the order; the full set is on our certifications page. The same specification is published on our Made-in-China storefront, where LVJIA is an audited supplier with a 5.0 store rating on Alibaba, 100% on-time dispatch and a response time under one hour.
Pricing for the enamel hot water tank starts at US$200 per m³, falling to US$180 from 10 and US$150 from 50, FOB Tianjin or Qingdao. The minimum order is one set and lead time is within 15 working days from Dezhou, Shandong. Check the anode every two to three years in hard water areas; replacing it is what determines the cylinder life.
Send the capacity you need and the space you have, and LVJIA returns an arrangement drawing with the panel schedule before you commit to anything. Our engineers answer specification questions directly through technical help, and the rest of the range sits on the Enameled water tank page.
Elsewhere in the enamelled range there is the insulated enamel water tank for insulated storage, the glass fused to steel tank for general-purpose duty, the enamel fire water tank for fire reserves and the enamel corrosion resistant tank for aggressive process liquids.
