BeZe BOILER HOSES, Boilers are devices used in solar hot water systems to heat the final usage water by heating the water in solar collectors and circulating it through flexible metal hoses in a tank, functioning as a serpentine. Using flexible boiler hoses as serpentine in boilers offers several advantages, such as increased efficiency due to the higher surface area compared to steel pipes, ease of installation due to their flexibility, and the high resistance of stainless steel to corrosion and scaling.
