Frequently Asked Questions
No, these radiators are specifically designed for closed hot water heating systems with temperatures ≤ 95°C. Steam and geothermal systems are strictly prohibited.
Cold spots at the top are usually caused by trapped air. Use a radiator key to bleed the air from the valve until water begins to flow, restoring full circulation.
Use a soft cloth, a vacuum with a brush attachment, or a mild soapy solution. Avoid harsh chemicals and abrasive scrubbers to protect the epoxy resin powder coating.
Water should comply with GB1576 standards: pH 9–12, Chloride ≤ 300 mg/L, Sulfate ≤ 150 mg/L, and dissolved oxygen ≤ 0.1 mg/L.
We offer four modes: same-side top/bottom, opposite-side top/bottom, opposite-side bottom/bottom, and 90° vertical bottom inlet/outlet.
We provide a 24-month warranty from the delivery date, offering free repair or replacement for any manufacturing defects.
