Frequently Asked Questions
They are designed for closed hot water heating systems with medium temperatures ≤ 95°C. Please note they are not suitable for steam or geothermal water systems.
Ensure water pH is between 9–12, chloride (Cl⁻) ≤ 300 mg/L, and sulfate (SO₄²⁻) ≤ 150 mg/L, as per the GB1576 standard.
Yes, they can be installed on tiled walls using appropriate heavy-duty anchors and brackets to ensure the weight of the steel is securely supported.
TRVs allow for precise temperature control in the bathroom, preventing overheating and significantly improving overall energy efficiency.
To prevent internal oxidation and maintain the integrity of the anti-corrosion layer, the system must be kept filled with water during non-heating periods.
No, we use advanced argon arc welding with double-side forming and professional polishing to ensure smooth, aesthetically pleasing weld seams.
