About Heat Exchangers

Heat exchanger is a device used to transfer thermal energy from one medium to another. Its’ design separates the mediums and does not allow them to mix, while allowing heat transfer to occur. Most of the heat exchangers used for hydronic and forced air heating can be categorized into liquid to liquid (or water to water) and liquid to air (water to air) types.

Brazed Plate Heat Exchangers

A brazed plate type heat exchanger (BPHE) consists of a series of metal plates stacked on top of each other and brazed in a vacuum furnace. A BPHE typically has a total of (4) piping connections - one inlet and one outlet for first liquid and the one inlet and one outlet for the second. The plates are connected in such a manner, that each liquid flows through its own designated channel and is separated from another liquid by a metal plate. These plates create a wall between the liquids and allow the heat transfer process to occur without mixing the two. Brazed plate type heat exchangers sold on PexUniverse have corrugated inner plates, which increase the surface area and improve the speed and efficiency of heat transfer.
These heat exchangers can be used for snow melting, solar, outdoor boiler and other heating applications.

Water to Air Heat Exchangers

A water to air type heat exchanger is comprised of a series of a supply and return copper manifold with thin copper tubes, which are finned with aluminum plates and encased into a steel frame. These units are often used with fans, blowers or other forced air equipment to move the air through the heat exchanger while water or other liquid is flowing. In hydronic heating applications, hot water is fed into the supply manifold and distributed through the copper tubes. The tubes transfer the heat to the attached, closely-spaced aluminum fins. When air is forced through the fins, it heats up, while water in the water to air heat exchanger gradually cools down and flows through the return manifold. From the return manifold, water is sent back to the boiler or other heating equipment, heated again and is recirculated back to the heat exchanger, where the process repeats.
Water to air type heat exchangers are mostly used for forced air heat applications, including indoor and outdoor wood boilers and furnaces.
