This circulator relay is a critical component in maintaining efficient boiler operation. When the relay fails, symptoms may include continuous pump operation, failure to circulate hot water, or inconsistent heating performance. Regular replacement of worn relays helps maintain system efficiency and prevents unnecessary pump wear.
