Where is an open feed water heater typically located?

An open feed water heater is typically located above the feed water pump. This positioning allows for gravity flow of the heated water back to the boiler, utilizing the principles of thermodynamics to maximize efficiency. By being installed at a higher elevation than the feed water pump, the open feed water heater can ensure that the heated water can flow downward by gravity into the boiler without requiring additional energy input from the pump.

This setup also facilitates the mixing of the condensate with the feed water, improving the overall thermal efficiency of the system. Including the heater in a higher position helps maintain the necessary pressure and temperature conditions for effective heat exchange, which is crucial for optimizing boiler performance and reducing the risk of pump cavitation.

The placement impacts the operational dynamics of the entire system such as ensuring adequate delivery of heated water to the boiler while maintaining system pressure and efficiency.
