Frequently Asked Questions
A 2-column radiator is slimmer and heats up faster, making it ideal for small rooms or narrow spaces. A 3-column radiator has more surface area and water capacity, providing higher heat output for larger or poorly insulated rooms.
No, these are exclusively designed for closed hot water heating systems. They should not be used directly with steam, geothermal heat, or industrial waste heat without a proper heat exchanger.
To extend the service life, it is recommended to maintain the system with full water protection during the non-heating season. In freezing conditions, the system should be drained to prevent damage.
Uneven heating is typically caused by trapped air within the system. This can be easily fixed by bleeding the radiator to remove the air pockets.
ST14 low carbon soft steel provides outstanding strength and ductility, ensuring that header components do not crack during the forming process, which enhances overall corrosion resistance.
Non-oxygen-barrier plastic pipes are not suitable for these systems. We recommend using standard-compliant pipes to ensure system longevity and performance.
