Plate Heat Exchanger For Domestic Hot Water

In practice both types of heat exchanger transfers energy from hot or cold fluid and ensures that the primary circuit does not mix with the secondary circuit therefore creating two completely independent separate heating or cooling circuits.

Plate heat exchanger for domestic hot water. To heat your domestic hot water two styles of heat exchangers are generally used. An extra pump is not required for a heat exchanger in my system. The colder water from the water tank or the drinking water supply passes through one end of this heat exchanger and heated fluid from the boiler jacket is passed through the other end. Then canalise directly the hot water to heat exchanger.

A brazed heat exchanger or a sidearm heat exchanger. Some installations use a small 10 or 20 plate brazed heat exchanger plumbed into the cold water supply that feeds the hot water heater. The high heat transfer efficiency for such a small physical size has increased the domestic hot water dhw flowrate of combination boilers. The water is heated instantaneously and only when required.

The small plate heat exchanger has made a great impact in domestic heating and hot water. Our packaged plate heat exchangers are designed for the instantaneous production of domestic hot water and provide a particularly good solution when plant room space is restricted. Domestic hot water dhw plate heat exchangers can be supplied as a plate gasket unit or supplied as a brazed plate unit. Turn off the other valves on the collector if hot water line is being fed from collector.

If you have 3 way or 3 way proportional valve on the heat exchangers hot water supply line make sure that valves are directly canalised from hot water to heat exchanger. A domestic hot water heat exchanger like a brazed plate heat exchanger is used here which is efficient takes up less space and is easier to maintain when compared with traditional heat exchangers. Our lok models are available with single or twin pump and can be installed for instantaneous operation or with direct storage vessels for applications which are subject to heavy peak hot water demand. Plate heat exchanger styles and options.

A hot water system using a plate heat exchanger does not store hot water. In the domestic context this is seen in the guise of combi boilers which fire up when you turn on the tap while additionally heating water for space heating.
