True or False: Bottom blow down valves are used for both steam and hot water systems.

Bottom blow down valves are indeed used in both steam and hot water systems. Their primary purpose is to remove sediment and impurities that accumulate at the bottom of a boiler. In steam systems, these valves help maintain the quality and efficiency of steam production by ensuring that contaminants that can affect boiler performance are regularly flushed out. In hot water systems, similar issues can arise, as sediment can lead to corrosion and reduced heating efficiency. Regular blow down procedures contribute to the maintenance and longevity of the boiler in both types of systems, highlighting the importance of this component in overall boiler management.
