Condensate return and boiler feed systems both function to return condensate to the boiler when gravity drainage is not an option. Condensate return systems collect condensation generated in a large system and pump it back to the boiler. Boiler feed pumps store and monitor the amount of condensate returning to the boiler to ensure it does not exceed the boiler's capacity. Controls help pumps run more efficiently by providing more control over the running time and duration. Replacement pumps, motors, seal kits, and switches help support maintenance and are often shared across both systems.
