What is a domestic hot water heat exchanger?

A domestic hot water heat exchanger like a brazed plate type heat exchanger is the perfect solution in such a case. Heated fluid from the solar energy based water boiler is sent from one end and the colder water from the water tank flows from the other end.

Where are flat plate heat exchangers used?

They are used for radiant, domestic water heating and even for heating swimming pools and spas. However, heat exchangers, especially flat plate heat exchangers have become extremely popular owing to their compact structure and higher heat transfer rates.

How does a flat plate heat exchanger work?

A plate exchanger consists of a series of parallel plates that are placed one above the other so as to allow the formation of a series of channels for fluids to flow between them. The space between two adjacent plates forms the channel in which the fluid flows.

How do you size a flat plate heat exchanger?

What Size Should the Plate Exchanger Have? Many customers ask, “how do you know what size plate exchanger to install in your domestic hot water tank?” A simple rule of thumb is 2 to 3 people in one house will determine a 10 plate. A 10 plate heat exchange is enough for 2 and 3 people.

How efficient are water heat exchangers?

Average efficiency may be around 85% to 90%. you can calculate the performance of the heat exchanger with respect to heat transfer rate to the maximum heat transfer which is calculated theoratically. there is many papers and books deals with heat exchanger you can follow it.

How efficient are water to water heat exchangers?

They can create water heating savings as high as 80%. Commercial and industrial facilities that use city sewers for their wastewater may use water to water heat exchangers in order to cool their wastewater to meet local codes.

How do I size a hot water heat exchanger?

How do I choose a plate heat exchanger?

Main Criteria for Heat Exchanger Sizing and Selection For a gasketed plate heat exchanger, the gaskets must be compatible with the fluids in the unit. Thermal fluid characteristics and product mix. If the heating or cooling fluid is susceptible to fouling, a corrosion resistant material may be needed. Location.
