The expansion vessel resistor is an electrical component used in some boiler expansion vessel assemblies. It plays a role in regulating or monitoring the operation of the vessel, helping to maintain proper pressure and performance within the heating system. As a specialized boiler spare part, this resistor is crucial for the accurate functioning of the expansion vessel, and replacing it when faulty can restore normal operation to your heating equipment.
