Domestic Hot Water (DHW) Plate Heat Exchangers can be supplied as a Plate / Gasket unit or supplied as a Brazed Plate unit. 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.
The plate exchanger will actually heat up the tank a little bit warmer than the tank is set for. So what will happen is the tank will never really turn on its coil system. The hot water tank will only turn on its coil system once you stop using your wood boiler. And that applies if your boiler is at about 180 degrees. Side arm vs plate heat exchanger for domestic hot water Dec 12, 2008 · Yep..the plate exchangers will plug pretty quick with hard water and should be cleaned yearly. The sidearms are'nt really effected by the hard water nearly at all. Plates do make faster heat but require a pump to circulate the water, where the sidearm works on convection and no pump is needed.
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. 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. Water-To-Water Plate Heat Exchanger 40 Plate A plate exchanger enables an outdoor boiler to provide domestic hot water. The plate exchanger is configured to pre-heat the water going into the domestic hot water heater. The plate exchanger allows outdoor boiler water to heat the domestic potable water WITHOUT MIXING these fluids.
