The pump/heat exchanger return tube is a critical part in the circulation system of a boiler. It connects the pump to the heat exchanger, allowing the return flow of water or heating medium. This component must be durable and correctly sized to ensure proper flow and heat transfer. Replacing a worn or damaged return tube can restore efficiency and prevent system failures. It is a common spare part for heating technicians and DIY enthusiasts maintaining gas or oil boilers.
